Repair & Calibration


Repair within the warranty period

The warranty period of the product will be one year from the date of purchase of the product.
If a problem occurs within the warranty period, we will repair it free of charge except in the following cases.

<Cases in which repair is charged even if within the warranty period>

  • Failure caused by fall, submersion or other accident caused by careless handling
  • Failure due to incorrect operation not in accordance with the instruction manual
  • Failure caused by not observing storage and usage conditions specified in the instruction manual
  • Failure caused by disassembly, repair, or modification
  • Problems caused by products other than the Company’s products
  • Failures due to natural disasters or fire

All repairs outside the warranty period will be charged.
The Company will not provide repairs in the following cases.

  • Products whose serial number has been removed
  • Products with remarkable damage due to battery leakage, submersion, strong impact, etc.
  • Products that have been discontinued seven or more years ago
    (The support period is set as a guide to seven years after the end of sales, taking into account the availability of parts for repair and so on.)
  • Products that have been disassembled, repaired or modified by the customer

Warranty after repair

The warranty period of a repaired product will be three months following the return of the repaired product.
If the failure recurs at the same location and with the same symptoms within 3 months after delivery, we will repair the product again at no charge. However, in the event that failure recurs due to the customer's negligence, or failure occurs in another place or with other symptoms, repair will be charged.

For products other than Leader brand products, a delivery record from the Company is required for support.
