r Setting the squelch threshold
If function S
q
L is called up, the following displays appear :
left LC display (7) S
q
L
right LC display (8) 00 to 200 Standard value 100
sensitivity (HI < -> LO)
Using the MHz switch (9) the squelch threshold can be altered
upwards or downwards in steps of 10 and using the kHz switch (10),
you can be altered upwards or downwards in steps of 5. The set value
is stored by pressing the STO key (3).
r Setting the sidetone level
Call up the SIdE function using the MDE key (4). The following displays
appear :
left LC display (7) SF 2
right LC display (8) 00 to 63 Standard value 32
(LO level HI)
Using the MHz switch (9) the sidetone level can be altered upwards or
downwards in steps of 10 and using the kHz switch (10), you can be

Operating Instructions
The various modes are comprehensively described, toghether with the
setting of the equipment configuration in the service mode, in the
Annex to the General Operating Instructions.
r Transmit/receive mode
Set the frequency of the local ground station in the preset display and
press the exchange key (5). Rotate the VOL control (1) to the centre
position.
NOTE
If the error message E2 appears in the left indication
during operation, the synthesizer is not latching and
further R/T operation is no longer possible. The VHF
transceiver must be checked in the next service station.
Operate the transmit button and call the ground station. Hold the
microphone close to the lips for optimum speech transmission.
NOTES
The green LED (6) indicates transmit mode. During
transmission a protective circuit prevents a frequency
change or frequency channel change even if the
frequency selector switch (9, 10) is rotated. The keying
functions on the control panel are also inhibited.
Where there is acoustic feedback during transmission the
side tone volume on the VHF transceiver must be turned
down (refer to Service Mode for adjustment).
