Operating Instructions

In the service mode the portable VHF station operates indepen- dent-ly of the settings on the control panel, on the frequency which was last set as the active frequency. Wenn the PTT-Key is pressed in the service mode, the display indicates in the top line the active frequency

The user can interlock his equipment configuration settings with the aid of a password. The portable VHF station is delivered from the factory without a password. Section SF15 “Entry of password for in- terlocking the equipment configuration” describes how to enter a password.

oSetting the squelch threshold

If function SF 1 is called up, the following displays appear :

The scan function is terminated by pressing the STO key. The portable VHF station then begins to operate again in the channel selection mode the CS in the bottom line goes out and CH appears. Exit from mode 2 is accomplished in the same way as described in the channel selection mode.

oMode 3 (indication of supply voltage)

The supply voltage is continuously measured. Indication occurs only in mode 3. The mode is selected by briefly pressing the MDE key once or several times (corresponding to the previous state) the active frequency on which the VHF station is ready for operation is shown in the top line and the measured voltage is displayed in the bottom line.

The active frequency (top line) can be changed using both frequency selector switches. A storage operation is activated using the STO key. This procedure is described in Mode 1.

Exit from mode 3 is achieved either by pressing the MDE key or the exchange key. When the exchange key is pressed the active frequency is stored as a preset frequency and a direct change to mode 1 occurs. This means that in mode 1 the previous active frequency is available as a preset frequency.
