NOTES
l
The triangle in the top line of the display indicates transmit mode.
During transmission a protective circuit prevents a frequency chan-
ge or frequency channel change even if the frequency selector
switch is rotated. The keying functions on the control panel are also
inhibited.
l
If the error message E2 appears in the top line during operation, the
synthesizer is not latching and further transmit / receive operation is
no longer possible. Than the portable VHF station is to be send the
next service station
If excessive feedback noises are experienced during transmission, the
sidetone volume must be turned down on the transceiver (refer to manu-
al of the installed transceiver).
Set the correct reception volume using the VOL control whilst the other
station is answering.
Switch on the squelch (muting) (press SQL key again). Weak reception
signals and reception noises are suppressed. The switch-on threshold
of the squelch can be set in the service mode.
