General information
Carrying case and transceiver together form a portable VHF station. The
easily-portable VHF station can be used, for example, for mobile and fi-
xed operations on airfields or landing strips. It an also be used in hot air
balloons, for ferrying aircraft or or recovery of gliders.
The carrying case contains the battery, speaker, antenna socket, the
way diode connecting socket for the microphone or microphone speaker
and the voltage converter. A microphone/speaker, a headset or a helmet
(ultralight) can be connected to the 5-way diode socket. The built-in bat-
tery is a maintenance-free rechargeable 12 V/ 2.2 Ah drylead battery.
The battery can be charged via the external d.c. socket. The charging
voltage can be varied between 10 V and 32 V. The charging time for a
heavily discharged battery is approximately 8 hours. The nominal opera-
ting time for the portable VHF station is approximately 6 hours at a key-
ing ratio of 1:10 normal radio traffic) and transmitter output power of 5 W.
Reception is then still guaranteed for a further 2 hours.
The portable VHF station contains a monitoring stage for the battery vol-
tage which is activated whenthe unit is switched on. If the battery voltage
drops to between 11 V and 10.5 V the indicator begins to flash.
The portable VHF station is ready for operation after the antenna is scre-
wed in place and microphone speaker plugged in.
When the ILL button is pressed, the panel lighting in the AR 4201 - ( ) co-
mes on for approximately 10 to 20 seconds.
