Warranty

This product manufactured by JAC is warranted to be free of defects in workmanship or performance for 2 years from

the date of installation by an approved JAC dealer or agency. This warranty covers the cost of all materials and labour

to repair or replace the unit, but does not include the cost of transporting the defective unit to and from JAC or its

designated warranty repair centre, or of removing and replacing the defective unit in the aircraft. This warranty does

not cover failures due to abuse, misuse, accident, or unauthorized alteration or repairs.

THIS WARRANTY IS VOID IF THE PRODUCT IS NOT INSTALLED BY AN AUTHORIZED JAC DEALER. If the on-

line warranty card is not completed, the product will be warranted from the date of manufacture.

Contact JAC for return authorization, and for any questions regarding this warranty and how it applies to your unit(s).

Installation Procedures

WARNING

: Loud noise can cause hearing damage. Set the headset volume to minimum before

conducting tests, and slowly increase the volume to a comfortable listening level.

CAUTION

The power input circuitry of the unit may be damaged if the installation does not conform to the

wiring instructions in this manual.

WARNING

: The messages are intended only to supplement, NOT replace, airframe messages such

as ‘low rotor RPM’, ‘engine out’ or ‘decision height alerting’. The message audio feature is intended

for use as a secondary alerting system where another device provides the primary annunciation.

2.4.1

Installation Limitations

Those installing the JA37-300, on or in a specific type or class of aircraft, must determine that the aircraft installation

conditions are within standards. The JA37-300 may be installed only by following the applicable airworthiness

requirements.
