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.

Mode 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 se-
lector 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 ex-
change 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 pre-
set frequency.
