Control elements and connections

1 Channel switch/SET button

Rotary switch for selecting the channel or  depending on the menu  for modifying the parameters

or the corresponding values.

The channel switch also has a pushbutton function (SET button): By briefly pressing the button,

the radio set switches to the next ten channels. If the button is pressed for more than 2 sec., the

radio set switches into the Settings menu. If the FUNC key is pressed prior to pressing the SET

button, the Memory menu is activated.

2 F/C key

Switching between the indication of Frequency and Channel on the display. In F mode, the

activated channel (e.g. 80CH) is displayed on top with the corresponding frequency (26,955) in

MHz underneath. In C mode, the activated country code (e.g. D for Germany) and the activated

channel (e.g. 17CH) are displayed.

3 ASC key

Switches the automatic squelch control (ASC) on and off. The ASC controls the squelch depending

on the field strength and the signal-to-noise ratio of a received transmission. A manual readjustment

of the squelch at different receiving locations is not necessary. For this reason, the manual squelch

is deactivated in this case.

4 TSQ key

Switches the selected tone squelch method on and off, the display shows CTC or DCS (the

requested method is adjusted in the Settings menu under S01 and S02). All TSQ methods can

only be activated in FM. As long as they are active, manual squelch and ASC are deactivated.

5 EMG key

Direct access to channel 9/19 (emergency key). By pressing the EMG key once, the radio set

switches over to channel 9, by pressing the key once again, channel 19 is activated (for this, the

type of modulation is used which was activated last for the corresponding channel). By pressing

the EMG key for the third time, the radio set returns to the initial channel.

6 DW key

Switches the dual watch function on and off. When the dual watch function is activated, the radio

set is ready-to-receive on two channels and automatically checks whether a signal is present on

one of both channels.

7 SCAN key

Switches the scanning function on and off. (The scanning type and delay time can be modified

in the memory menu under SCN and SCT).
