TO SCAN
Briefly press
F
followed by . The
icon will flash and the channel numbers will
change as the radio scans through the channels. To change the scan direction while
scanning, briefly press or .
To stop scanning, briefly press
F
followed by . The
icon will stop flashing and
the radio will return to normal operation.
SCANNING FEATURES
• If a signal is received, the scan is paused allowing you to transmit and receive on
that channel. During this time the
icon will continue to flash to show that the
scan is still active. Once the channel has been inactive for 5 seconds the scan will
automatically resume.
• Pressing the
PTT
switch while the radio is scanning will jump to the working
channel allowing you to transmit and receive on that channel (the working channel
is the channel the radio was on at the time the scan was activated). During this time
the
icon will continue to flash to show that the scan is still active. Once the
working channel has been inactive for 5 seconds the scan will automatically resume.
• If the scan is paused on a busy channel that you don’t wish to listen to, press the
or keys to ‘skip’ over the channel and continue scanning.
TIP:
The Scan mode will reduce the overall battery life because the Standby (battery
saver) feature is overridden. If the battery is running low you should avoid scanning to
conserve power.
CTCSS, DCS AND SILENT MODE
CTCSS (Continuous Tone Coded Squelch System) and DCS (Digital Coded Squelch) are
similar Squelch quieting systems that allow groups of users to share the same channel
without disturbing each other. The CTCSS system uses 1 of 50 low frequency tones
to open and close the Squelch on the radio. The DCS system is similar to CTCSS but
uses 1 of 104 digital codes to control the Squelch. When CTCSS or DCS is enabled on
your radio, only signals that are using the same code as your radio will be heard in the
speaker and the Squelch will remain closed to all other signals.
NOTE:
CTCSS and DCS codes do not prevent others from hearing your transmission.
CTCSS/DCS tones are switched off by default. To use CTCSS/DCS you must first enable
a suitable CTCSS/DCS code using the Menu (see Menu options for more details).
Your choice of CTCSS or DCS will largely depend on which is currently being used by
other radios in your group. If neither system is currently in use, you can make your
own choice. There is no difference in performance between the two systems. Once a
CTCSS or DCS code has been enabled, the display will show (for CTCSS) or
(for DCS). You can now make selected channels ‘quiet’ by enabling Silent mode on
those channels.
To activate or deactivate Silent mode on a channel
1. Select the required channel.
2. Press and hold the
SQL
key. The selected CTCSS or DCS code will be displayed
on that channel.
