Description
"LOW BATT" appears after the supply voltage
of the transceiver dropped below the
threshold defined in the Installation Setup.

have a reduced performance. Below 10 volts
the speaker output is switched "OFF"!
Possible reasons for indication:

- Power interrupts,
- General problem of power supply,
- Wrong (too high) adjusted threshold in
Installation Setup (refer to LOW BATTERY TRH
