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

2 F/C key
Switching between the indication of
F
requency and
C
hannel 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
a
utomatic
s
quelch
c
ontrol (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

). 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
