Appearance about every 5 seconds.
The transceiver has detected an internal failure during normal
operation.
Depending on failure reason, the device may be still operable
with degraded performance or not operable at all. Possible
reasons for indication:
- Out of specified environmental conditions
- HW or SW failure inside the transceiver.
Contact maintenance shop for assistance.

3.3 Safety Instructions
The following instructions must be followed for safe operation of the portable VHF station:
A speech test is to be performed before startup and it should be noted that if the speech test is carried
out close to the ground station the results may be positive even if the antenna cable is broken or
short-circuited. In this case at a distance of 5 to 10 km communication might not be possible.
Use a loud voice for speech communication and hold the microphone close to the lips. Otherwise cabin
noise can be intrusive and make understanding difficult.
Use only microphones or headsets which are suitable for use in aircraft.
For power supply voltages below 10 V the speaker output of the transceiver is automatically switched
off, without dedicated notification of the user!
For power supply voltages below 10V pilots have to use the headphone output.
Depending on settings of installation setup “LOW BATT” may be indicated if supply voltage drops be-
low predefined threshold. If this threshold is adjusted in range 10.2 … 10.5 V this “LOW BATT” warning
may be used as an indication, that pilot should connect his headset, because speaker may be switched
off soon.
