Warning and Failure Indications
Display Contents
Description
LOW BATTERY
IC
118.005
Appear in 3-second
cycle
"LOW BATT" is indicated if the supply voltage of the
transceiver is below the threshold defined in the
installation setup.
The transceiver is still operable but may have a
reduced performance depending on supply voltage.
Possible reasons:
Accumulator capacity problems (gliders),
Power interrupts,
General power supply problems,
Setting for low battery threshold too high
STUCK PTT
IC
118.005
Appear in 3-second
cycle
"STUCK PTT" is indicated after 120 seconds of
continued transmission. The transceiver goes back
to receive mode even if the PTT line is still active
(GND).
For initiating a new transmission, the PTT line needs
first to become inactive (open).
Possible reasons:
Transmission lasts more than 120 seconds.
PTT-key is stuck.
PTT line permanently grounded (short circuit in
installation).
TX HOT
IC
118.005
Appear in 3-second
cycle
"TX HOT" is indicated if the internal device
temperature exceeds +90 °C.
Transceiver is still operable. Performance of
transmitter is reduced.
Possible reasons:
Very hot environmental temperature, long
transmissions times and insufficient airflow
conditions.
FAILURE
IC
118.005
Appear in 3-second
cycle
The transceiver has detected an internal failure
during normal operation.
Depending on failure reason, the device may still be
operable with degraded performance, or not
operable at all.
Possible reasons:
Specified environmental conditions
HW or SW failure inside the transceiver.
Contact maintenance shop for assistance.
