a)
the enter key ( 6 ),
b)
the PTT key ( 12 ),
c)
the call tone key C ( 5 ), or
d)
the menu key
( 11 ).
13) VOX function
While the VOX function is active, the unit switches automatically
to transmit mode when the sound level at the microphone ( 9 ) is
above a certain threshold. If the volume level at the microphone
( 9 ) remains below this threshold for a certain time, which is
called the VOX delay time, the radio switches back to receive
mode. Thus, you can communicate without having a hand at the
unit.
If the squelch is open because of a received signal the VOX func-
tion is disabled. The following instructions show how to activate
the VOX function and how to work with it:
Depress the menu key
( 11 ) three times until the VOX symbol
( = VOX ) flashes in the LCD. Now, the VOX sensitivity needs to
be set. To increase or decrease the VOX sensitivity, use the up-
and down-keys
▲
( 3 ) and
▼
( 4 ).
The bar meter in the lower right corner of the display, which nor-
mally indicates the volume level, shows the current VOX sensitiv-
ity. The pitch of the confirmation tone does not depend on the cur-
rent VOX sensitivity. At the ends of the adjustment range two high
signal tones are audible. If the VOX sensitivity is set to the lowest
possible value, so that no bar is visible, the VOX function is deac-
tivated.
To return to the normal receiving mode, press :
a)
the enter key ( 6 ) once,
b)
the PTT key ( 12 ) once, or
c)
the menu key
( 11 ) twice.
a)
the enter key ( 6 )
b)
the call tone key C ( 5 ), or
c)
press the menu key
( 11 ) another three times.
The table of the CTCSS frequencies can be found on page 15.
11) Channel scan function:
If the channel scan function is activated, the unit runs through all
channels, until it has found an occupied one. In this case, the
squelch opens, and the unit stops on that channel. To start the
channel scan function press the scan key S ( 13 ). The scan sym-
bol (= SCAN ) will appear on the bottom of the display. The scan-
ning stops on every occupied channel. It continous searching 4
seconds after the signal has dropped below the squelch thresh-
old.
To deactivate the scan function and to stay on the actual channel,
press the :
a)
scan key S ( 13 )
b)
enter key ( 6 ).
12) Dual watch function
This function allows you to monitor two channels at a time. The
following instructions show how to activate the dual watch func-
tion:
First, select the first survey channel. Then, press the menu key
( 11 ) four times until the dual watch symbol ( = DW ) starts blink-
ing in the LCD. Now, select the second channel with the keys
▲
( 3 ) or
▼
( 4 ). The dual watch symbol ( = DW ) appears con-
stantly and the receiver switches twice per second between the
two selected channels. If one of the two selected channels
receives a signal, the receiver remains on that channel until the
signal ends, before it goes back to switching back and forth
between the selected channels.
To deactivate the dual watch function, press :
