Operating Instructions

oTransmit/receive mode

Set the frequency in the preset display and press the exchange key. Rotate the VOL control to the centre position.

Operate the transmit button and call the other station. Hold the microphone close to the lips for optimum speech transmission.

NOTES

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.

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

CAUTION

If excessive feedback noises are experienced during transmission, the sidetone volume must be turned down on the transceiver (refer to manual 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.
