Operating Instructions

oScan function

If the scan function is activated in the equipment configuration, pressing the STO key changes from the channel selection mode to the scan function. In the scan function, the frequency appears in the top line of the display and the associated channel with the preset CS is shown in the bottom line.

In the scan function, either all the occupied storage channels or a required range of storage channels can be scanned. The scanning range is specified in the service mode. The various storage channels are scanned in short intervals. If the microprocessor finds a carrier in one of the channels, it holds a short on this channel and checks whether an evalua- table signal is present. If no evaluatable signal is present, it switches to the next channel and then reverts to the short intervals (milliseconds ran- ge).

In the event of an evaluatable reception signal being received the portable VHF station remains on the storage channel until an evaluatable reception signal is no longer present. After a hold time 0 to 60 seconds (can be set in the service mode) the scanning of the storage channels at short intervals begins again. The set squelch level is the criterium for an evaluatable reception signal, regardless of whether the squelch is activated or not.

If the portable VHF station is equipped with channel priority, this function can be switched ON or OFF in service mode SF 18

NOTE

If an adequate signal is required on the priority channel with option channel priority switched ON, the portable VHF station automatically leaves the SCAN mode and is ready for transmission and receive on this chan- nel. For return to the SCAN mode, again press the STO key.
