•
Select the CTCSS/DCS tone with the UP/DN buttons
•
There are 38 CTCSS and 99 DCS tones to choose from
•
Briefly press PTT to confirm.
Advantage: Enables selective reception of certain stations
within a channel.
Disadvantage: All remote stations must also be equipped with
CTCSS/DCS. Lower reception sensitivity and thus lower range.
5.5.3. Manual squelch
Turn the SQ squelch control to suppress the channel noise. The
further you turn the control, the stronger a received signal has
to be to open the squelch.
Usually, the squelch is set to just barely mute the speaker.
Advantage: Manual squelch can be set so that only close
range stations can be heard.
Disadvantage: Manual setting is required. If the squelch is
mistakenly set too high, it decreases the reception sensitivity
and thus the range.
5.6. AM/FM mode selector
AM or FM modulation can be selected
by pressing the AM/FM button.
The current setting is displayed on the
LCD screen.
If a channel from 41 to 80 (only
available in region mode d) is set, the
device switches to FM mode regardless
of the setting on the lower channels.
