Set any 4-digit numerical code using the kHz (10) (steps of 1) or MHz
(9) (steps of 10) switch. Store the numerical code by pressing the STO
key (3).
NOTE
As soon as a password is given a 0 appears in the bottom
line when the service mode is called up. The numerical
code must then be input using the MHz (9) or kHz switch
(10) and press the STO key. If the VHF transceiver
detects a false numerical code, it automatically switches
to the last mode. If the password is to be erased or
changed, this is done by calling up the service mode using
the old password. The SF 15 function is then chosen and
either a 0 is entered everywhere or the changed
numerical code is entered.
r Setting the dynamic mike input sensitivity
Call up function SF 9 using the MDE key (4). The following displays
appear :
left LC display (7) SF 9
right LC display (8) 00 bis 63 Standard value 32
(LO sensitivity HI)
The dynamic mike input sensitivity can be changed upwards or
downwards using using the kHz (10) (steps of 1) or MHz (9) (steps of
10) switch. The set value is stored by pressing the STO key (3).

Operating Instructions
GENERAL INFORMATION
The VHF transceiver AR 3209 enables voice communication on
760 channels in the 118.000 MHz to 136.975 MHz range with a channel
spacing of 25 kHz. It complies with the requirements of ICAO Annex 10
valid from 01.01.1995.
The VHF transceiver is designed with sufficient mechanical strength to
enable it to be fitted in an aircraft without any limitations. There is no
restriction within the verified environmental classes on fitting in the
instrument panel or centre console or operating console, or fixed
mounting in the fuselage, of all types of aircraft including helicopter.
