RePlACINg THe BATTeRy
To install or replace the ANR battery, open the battery door by sliding the door in a downward
motion until it unlatches and lift up as shown in diagram A.
Slide the 9-volt battery in with the larger battery contact on the bottom. If you put the battery in
upside down, it will not activate. See diagram B.
Battery life is dependent on the ambient noise in the aircraft, but should provide a minimum of
20 hours of continuous use.
CAUTION:
Bias voltage supplied to the microphone must come from voltage and resistance
ranges specified below. Voltages supplied in excess of those stated in the specifications can
cause microphone failure and void the warranty. The mic audio signal is present between the
ring and barrel of the mic plug; tip is reserved for transmit keyline.
