Warranty and Repair
Calibration
Before leaving the factory, all GRAS products are calibrated in a controlled laboratory environ-
ment using traceable calibration equipment. An individual test certifi cate is included with each
product. The calibration information is also stored in the built-in TEDS.
Warranty
All GRAS products are made of high-quality materials that will ensure life-long stability and
robustness. The 67AX is delivered with a 5-year warranty. Damaged diaphragms in microphones
can be replaced. The warranty does not cover products that are damaged due to negligent use,
an incorrect power supply, or an incorrect connection to the equipment.
Service and Repairs
All repairs are made at GRAS International Support Center located in Denmark. Our Support
Center is equipped with the newest test equipment and staff ed with dedicated and highly skilled
engineers. Upon request, we make cost estimates based on fi xed repair categories.
If a product covered by warranty is sent for service, it is repaired free of charge, unless the
damage is the result of negligent use or other violations of the warranty. All repairs are delivered
with a service report, as well as an updated calibration chart.
GRAS Sound & Vibration continually strives to improve the quality of
our products for our customers; therefore, the specifi cations and
accessories are subject to change.
