Standard Limited Warranty Terms & Conditions
Effective for products invoiced on or after 10 October 2026.
Macnman Technologies Pvt. Ltd. (“Macnman”) builds industrial IoT devices for monitoring, automation and long-term field operation. This Standard Limited Warranty is the only warranty Macnman gives on its products. It sets out what is covered, what is not, and how to make a claim.
By purchasing, installing or using a Macnman product, the customer accepts these terms.
Warranty at a Glance
| Item | Warranty period |
|---|---|
| Macnman hardware: enclosure, PCB, electronics, RF and communication modules | 2 years |
| Optical, ultrasonic and other detachable sensor probes | 12 months |
| Gas sensing elements, soil probes and pH probes | 6 months |
| Rechargeable batteries | 6 months |
| Repaired or replaced products and parts | Remainder of the original period |
| Non-rechargeable batteries, consumables and wear parts | Not covered |
| Third-party accessories, software and platforms | Not covered by Macnman |
All periods run from the date of Macnman’s invoice. This table is a summary; the sections below set out the full terms and prevail if the two differ.
1. Scope
This Limited Warranty applies only to Macnman-branded hardware supplied by Macnman or by a Macnman-authorized distributor. Macnman products are designed and sold for commercial and industrial use.
It does not cover:
- Software, applications, dashboards or cloud platforms not supplied by Macnman
- Third-party sensors, modules, accessories or peripherals, including those supplied alongside a Macnman product (power adapters, antennas, SIM cards and similar). These carry only their original manufacturer’s warranty, if any
- Products not manufactured or supplied by Macnman, or bought second-hand or from an unauthorized seller
- Samples, prototypes, demo and evaluation units, units supplied free of charge, and custom or OEM designs. These are supplied “as is” unless Macnman agrees otherwise in writing
Macnman is not responsible for interoperability or compatibility issues arising from components, applications, network servers or integrations that Macnman has not approved in writing.
2. Warranty Coverage
Hardware Warranty (2 Years)
Macnman warrants that its hardware will be free from defects in materials and workmanship for two (2) years from the date of Macnman’s invoice, when installed and operated as described in the product’s user manual and datasheet.
The hardware warranty covers:
- Mechanical enclosures
- PCB and internal hardware assemblies
- Electronic components
- RF circuitry and communication modules
This warranty covers manufacturing defects only.
Batteries and Sensor Probes
Batteries and sensor probes are excluded from the 2-year hardware warranty. They are covered for the shorter periods below, counted from the same invoice date:
- Optical, ultrasonic and other detachable sensor probes: 12 months
- Gas sensing elements and cartridges (such as H₂S, NH₃, CO, CO₂, CH₄ and O₂): 6 months
- Soil probes: 6 months
- pH probes: 6 months
- Rechargeable batteries: 6 months
- Non-rechargeable batteries: no warranty
Where a product’s datasheet states a different period for one of these items, the datasheet period applies.
The following are normal behaviour and are not defects:
- Gradual loss of battery capacity, and battery life shorter than the datasheet estimate
- Sensor drift, loss of sensitivity, and the ageing or depletion of a sensing element
- The need for periodic cleaning, recalibration or replacement of a probe
Embedded Firmware
Firmware installed by Macnman is supplied “as is”. Macnman does not warrant that firmware will be uninterrupted, error-free or suited to a particular application.
If the firmware shipped with a product stops the hardware from working materially as its datasheet describes during the hardware warranty period, Macnman’s only obligation is to make reasonable efforts to provide a corrected version.
Repaired or Replaced Products
A repair or replacement does not extend or restart the warranty. A repaired or replaced product or part is covered only for the remainder of the original warranty period.
How the Warranty Period Is Counted
- The period starts on the date of Macnman’s invoice to its direct customer. For products bought through a distributor, this is Macnman’s invoice to that distributor.
- The period is not extended by storage, late installation, non-use, time in transit or time spent in the RMA process.
- A claim must be reported to Macnman before the period ends.
3. Remedies
If Macnman’s inspection confirms a defect covered by this warranty, Macnman will, at its sole option:
- Repair the product, using new or refurbished parts
- Replace it with a new or refurbished product of equivalent function, which may be a newer compatible model
- Refund the price paid to Macnman for the affected unit, less reasonable depreciation for use, where repair or replacement is not reasonably practical
Replaced products and parts become the property of Macnman. Service is subject to component availability.
Warranty service is carried out at Macnman’s service centre. It does not include:
- Removal of the product from site, or reinstallation
- Site visits, travel, access equipment or labour at the installation site
- Re-commissioning, reconfiguration or recalibration after return
- The cost of any substitute product or service
On-site service is available on request at Macnman’s prevailing rates.
These remedies are the customer’s sole and exclusive remedies for any defect in a Macnman product.
4. Transferability & Responsibilities
This Limited Warranty is non-transferable and applies only to:
- Direct customers purchasing from Macnman
- OEM and distributor partners with valid commercial agreements
End users must contact the distributor from whom they purchased the product.
Distributors, resellers and agents are not authorized to change or extend this warranty on Macnman’s behalf. Any additional promise they make is their responsibility alone.
Customers are responsible for:
- Confirming that the product is suitable and compatible for their application before deployment
- Installing, operating and maintaining the product as the user manual and datasheet describe
- Informing end users about correct installation and integration
- Maintaining backups of data and device configuration
Macnman is not liable for any data loss resulting from installation, servicing, firmware updates or device failure.
5. After-Sales Service & RMA Handling
Conditions for a Claim
Macnman accepts a warranty claim only when all of the following are met:
- The defect is reported in writing to support@macnman.com within the warranty period, and within 15 days of the defect first appearing
- Valid proof of purchase is provided
- The serial number label, QR code and warranty seal are intact and legible
- The product has been paid for in full. Macnman may suspend warranty service while any payment for the product is overdue, and the warranty period continues to run during that time
- An RMA Number has been issued by Macnman before the product is shipped
Products sent without a valid RMA Number may be refused and returned at the customer’s cost. An RMA Number is valid for 30 days from the date of issue.
RMA Request and Approval
Required details:
- Product model
- Serial number / QR code / MAC ID
- Purchase invoice
- Fault description
- Installation images (if applicable)
- Logs or data (if applicable)
Before shipping, the customer must back up all data and settings and remove SIM cards, memory cards and accessories that were not requested. Macnman may reset a returned product to factory settings and update its firmware, and is not responsible for data, SIM cards or accessories sent with it.
Shipping & Logistics
- Customer → Macnman: The customer bears shipping, packing, insurance and handling. Risk of loss or damage stays with the customer until Macnman receives the product.
- Macnman → Customer: For approved warranty claims, Macnman pays standard return shipping within India. For destinations outside India, the customer bears international freight, insurance, customs duties and taxes in both directions.
- All other cases: For out-of-warranty, excluded and no-fault-found cases, the customer pays shipping in both directions.
Inspection & Service
Macnman inspects every returned product. Macnman’s findings on the cause of a failure, and on whether it is covered by this warranty, are final.
If no fault is found, or the failure is not covered, Macnman will return the product unrepaired or offer a paid repair. A diagnostic fee may apply.
If the customer does not approve a quotation, make payment or arrange return within 60 days of Macnman’s written notice, Macnman may recycle or dispose of the product without liability.
Out-of-Warranty Repair Charges
The repair cost will be communicated in advance and approved by the customer before repairs begin. Parts replaced in a paid repair are warranted for 90 days from the date of return shipment. The rest of the product is not.
The full return procedure is described in the Return / Replacement / RMA Policy.
6. Warranty Exclusions
What Is Not Covered
The warranty does NOT cover:
- Accidental or physical damage, including drops, impact and excessive vibration
- Cosmetic damage that does not affect function, such as scratches, dents, fading, UV discolouration and label wear
- Operation or storage outside the datasheet limits for temperature, humidity, pressure, supply voltage or load
- Incorrect power supply, reversed polarity, over-voltage, surge, electrostatic discharge, lightning or faulty earthing
- Water or dust ingress caused by incorrect gland, cable entry or sealing, or by an opened enclosure. The ingress protection rating applies only when glands, seals and covers are fitted as the manual describes
- Damage from chemicals, fertilizers, salt, corrosive materials, insects or rodents
- Improper installation, wiring or mounting, misuse, neglect, or use other than as intended
- Use of unofficial accessories, antennas, batteries or power adapters
- Software, platforms, network servers, gateways, SIM or carrier services, and network coverage not provided by Macnman
- Damage due to incorrect firmware flashing, or failure to install an update that Macnman has advised
- Wear-and-tear and consumable items such as cables, connectors, glands, seals, desiccant and mounting hardware
- Loss or damage in transit, including damage from inadequate packaging on return
- Theft, vandalism, loss, and force majeure events such as fire, flood, storm and earthquake
- Use in life-support, safety-critical or other applications where failure could cause injury, death or environmental harm
Wireless range, battery life, accuracy and similar figures in Macnman datasheets are typical values measured under stated test conditions. Results at a customer site depend on the installation and environment, and a variation from those figures is not a defect.
What Voids the Warranty
The warranty on a product ends immediately if:
- The product is opened, modified, repaired or serviced by anyone other than Macnman or a person Macnman has authorized in writing
- A warranty seal is broken or tampered with
- The serial number label or QR code is removed, altered or made illegible
- Non-Macnman firmware is installed, or the bootloader or security protections are altered
7. Software & Firmware Updates
Macnman may release firmware updates to enhance product performance, but is not obliged to do so.
Customers are responsible for:
- Keeping the device updated
- Ensuring correct firmware installation
Improper flashing or installation of non-Macnman firmware voids the warranty.
8. Technical Support
Remote technical support by email is available during the warranty period at no additional cost. It is provided on a best-effort basis and covers the operation of the Macnman product itself.
The following are not included and are chargeable:
- Site visits, installation and commissioning
- Custom integration, payload decoder or dashboard development
- Configuration of third-party platforms, network servers or gateways
- Training
Post-warranty technical assistance may be subject to service fees. Guaranteed response times and extended cover are available under the AMC / Extended Support Policy.
9. Modifications to Products
Any modification, repair or opening carried out by unauthorized personnel voids the warranty.
OEM partners must follow Macnman’s RF, PCB and integration guidelines to retain module warranty.
Macnman may change the design, components or specifications of its products at any time. It is not obliged to apply such changes to products already sold.
10. Disclaimer of Other Warranties
To the maximum extent permitted by law, this Limited Warranty is the only warranty Macnman gives. It replaces all other warranties, conditions and representations, whether express, implied or statutory, including any implied warranty of merchantability, satisfactory quality, fitness for a particular purpose or non-infringement.
No statement by an employee, distributor or agent, and nothing in a datasheet, brochure, proposal or website, creates a warranty or extends this one.
Macnman products are not fault-tolerant. The customer is responsible for the design of its overall system, including any redundancy, alarms or backups its application requires.
11. Limitation of Liability
To the maximum extent permitted by law:
- Macnman’s liability for a defective product is limited to the remedies in Section 3.
- Macnman’s total liability arising from any product, on any legal basis, will not exceed the amount actually paid to Macnman for the affected unit.
Macnman is not liable, whether in contract, tort (including negligence) or otherwise, and even if advised of the possibility, for:
- Loss of profit, revenue, business, contracts or goodwill
- Downtime or operational interruptions
- Data loss, missed alerts or failed notifications
- Loss of or damage to crops, stock, goods, equipment or property monitored or controlled by a product
- The cost of substitute products, removal or reinstallation
- Third-party claims
- Indirect, incidental, special, punitive or consequential damages
See also the Legal Disclaimer & Limitation of Liability.
12. Force Majeure
Macnman shall not be liable for warranty obligations delayed or prevented by events beyond its reasonable control, including:
- Natural disasters
- War or terrorism
- Epidemics
- Government actions
- Labor strikes
- Supply chain disruptions and component shortages
- Carrier, power or network outages
13. Compliance with Laws
Customers must ensure that the installation and operation of Macnman devices comply with all applicable laws and industry standards in their country or region, including radio, electrical, safety and export regulations.
14. Indemnification
Customers agree to indemnify and hold Macnman harmless from any claims, losses, costs or liabilities arising from:
- Misuse, improper installation or unauthorized modification of Macnman products
- Use of a product in an application for which it is not intended, including safety-critical applications
- The customer’s own systems, integrations or services
- The customer’s breach of applicable law or of these terms
15. Governing Law & Disputes
This Limited Warranty is governed by the laws of India.
The parties will first try to resolve any dispute through discussion. If it remains unresolved, the dispute will be settled by arbitration in Pune, Maharashtra, in English, under the Arbitration and Conciliation Act, 1996. Subject to that, the courts at Pune have exclusive jurisdiction.
Where the law of a customer’s country gives rights that cannot be excluded or limited by contract, those rights are not affected. In that case Macnman’s liability is limited to the minimum that law allows.
16. General Terms
Order of precedence. Where a quotation, proforma invoice or written agreement issued or signed by Macnman states a different warranty period or different warranty terms for a specific order, that document applies to that order. Terms printed on a customer’s purchase order do not apply. If this policy and another Macnman policy differ on a warranty matter, this policy applies.
Severability. If any clause within this warranty is found invalid by law, the remaining clauses shall continue to be enforceable.
No waiver. If Macnman does not enforce a term on one occasion, it may still enforce it later.
Warranty policy updates. Macnman reserves the right to modify or update this Warranty Policy at any time without prior notice. Products invoiced before the effective date above remain covered by the warranty terms that applied on their invoice date.
