Channel selection
There are three ways to select a channel. First, by using the numeric
keys. Second, by using the up or down arrows to move to a higher or
lower number. And third (only for channel 16), by pressing 16.
3.6.1
Channel selection by numeric keys
Press the numeric keys in sequence until the desired channel
number is shown on the display:
If available in your VHF system, a private channel can be selected
by pushing the keys Shift and P before the numeric keys. The
display then shows the letter P in front of the channel number.
3.6.2
Channel selection by up and down arrows
First, press CH to display the current channel. Then use the up or
down arrow to locate the channel you require. Finally, press CH
again to exit the selection process.
3.6.3
Channel selection by quick select key 16
Pressing 16 switches to channel 16 at any time.
3.7
Squelch control
The squelch setting is for suppressing background hiss during a call.
Never use a higher squelch setting than is necessary.
3.7.1
Setting the squelch level manually
First, press SQ to display the current squelch setting (below SQ on
the display). Then use the up or down arrow to adjust. Finally,
press SQ again to exit the selection process. If you press the up or
down arrow for more than 4 seconds, the squelch level goes up or
down automatically.
3.7.2
Setting the squelch level automatically
Your VHF DSC can automatically optimise the squelch level. To do
this, press Shift, SQ.
3.8
Adjusting the volume
The volume can be adjusted by pressing the up or down arrow from
00 (muted) to 15 (loudest). Once the unit is switched OFF and back
ON, the volume will revert to the default setting described below.
The Volume has a default setting for both the loadspeaker and the
earpiece which can be independently adjusted from 00 (muted) to 15
(loudest).
To adjust the loudspeaker:
1.
Press Shift, Func.
2.
Press the up or down arrow twice to display GENERAL.
3.
Press right arrow to display ILLUMINE.
4.
Press up arrow to display SOUND.
5.
Press right arrow to display EARPIECE.
6.
Press up arrow to display LOUDSPEAKER.
7.
Press right arrow to display NORM.
8.
Now use the up or down arrow to increase or reduce the setting.
9.
Once you are satisfied you have keyed in the required setting,
press Shift, Func to exit.
If the loudspeaker is active, its setting is always shown on the
display. Only when the handset is off its rest and the speaker is not
set to be active is the volume level of the earpiece shown.
When setting any level using the up or down arrows, holding the key
down for more than 1 second will progress automatically until the
limit is reached.
3.9
Muting the loudspeaker
If the loudspeaker is active, pressing PTT automatically mutes it, and
releasing PTT reactivates it.
To mute the loudspeaker without pressing PTT, press Shift and the 8
key (which also carries a speaker symbol). To reactivate the
speaker, press Shift and 8 again. When the loudspeaker is muted,
the display includes the appropriate icon.
3.10 Setting the transmitter power
The transmitter power is either 25W (the default) or 1W: there are no
intermediate settings. To change the TX power level, press Shift,
Power: when the power is 1W, the indicator light will register this.
Please note that some channels are programmed to operate only at
low power, i.e. 1W.
3.11
Dimming the display
The handset features a display backlight, a keyboard backlight and
lights for the five indicators (CALL placed on handset, TX, 1W, US or
BI, and ALARM). The brightness of all of these can be adjusted in
four levels from 3 down to 0. The default setting is 3. To reduce the
level, press Shift and then hold down the 7 key (which also says
DIM). The level is indicated in the display and reduces every second.
Subsequently, pressing any key will return the brightness to level 3.
