THE WARRANTIES AND REMEDIES CONTAINED HEREIN ARE EXCLUSIVE AND IN 

LIEU OF ALL OTHER WARRANTIES EXPRESSED OR IMPLIED, INCLUDING ANY LIABIL-
ITY ARISING UNDER WARRANTY OF MERCHANTABILITY OR FITNESS FOR A PARTICU-

DAMAGES, SO THE ABOVE LIMITATIONS MAY NOT APPLY TO YOU.

To obtain warranty service, call the GARMIN Customer Service department (913/397.8200) 

for a returned merchandise tracking number. The unit should be securely packaged with the 
tracking number clearly marked on the outside of the package, and sent freight prepaid and 
insured to a GARMIN warranty service station. A copy of the original sales receipt is required 
as the proof of purchase for warranty repairs. GARMIN retains the exclusive right to repair or 
replace the unit or software or offer a full refund of the purchase price at its sole discretion. 
SUCH REMEDY SHALL BE YOUR SOLE AND EXCLUSIVE REMEDY FOR ANY BREACH 
OF WARRANTY.

NOTE: The GTX 320A owner accepts all responsibility for obtaining 
the proper licensing before using the transponder.

NOTE: The coverage you can expect from the GTX 320A is limited 
to “line of sight”.  Low altitude or aircraft antenna shielding by the 
aircraft itself may result in reduced range.  Range can be improved 
by climbing to a higher altitude.  It may be possible to minimize 
antenna shielding by locating the antenna where dead spots are 
only noticed during abnormal fl ight attitudes.

CAUTION: The GTX 320A should be turned off before starting or 
shutting down aircraft engine(s).
