RCU6512
DV17551.03 Issue 03 June 2020
Excessive pulses on the DC bus of the aircraft may cause damage on electrical
circuits of any installed instrument.
Do not turn on the device during engine start or shutdown.
Do a voice communication test before starting any operation.
•
Notice that, if the communication test is carried out close to a ground station,
the results can be positive even if the antenna cable is broken or short-
circuited.
o
Caution!
Then a communication might not be possible at a distance of 5
to 10 km and above.
•
Speak always loud, clear and not too fast for optimal voice communication.
•
Keep the microphone always close to the lips otherwise a special
suppressing circuit in the VHF COM will not be capable to suppress normal
noise.
•
Use only microphones or headsets which are applicable for specific
installations.
o
In aircraft made of wood, synthetic materials or in gliders or helicopters,
incoming radiation can affect the integrated amplifier of the microphone
(feedback), then the ground station receives a whistling and/or heavy
distortion.
