Scanning Features
• I f a signal is received, the scan is paused, allowing you to transmit
and receive on that channel. The radio will automatically resume
scanning a few seconds after the last reception or transmission.
• P ress the PTT switch while the unit is scanning to jump to the home
channel (the home channel is the channel the radio was on at the
time scanning was activated). You can then transmit and receive on
that channel. The radio will automatically resume scanning a few
seconds after the last reception or transmission.
• W hen the unit has stopped on a busy channel, press the
'skip' over the busy channel and continue scanning.
TIP:
The Scan mode will reduce the overall battery life because the
Standby (battery saver) feature is overridden. You should avoid scanning
if the batteries are running low and you need to conserve power.
Memory Function
The Memory function enables and disables the current channel to be
memorised into the scanning list. When the channel is memorised with
the 'M' icon on the LCD, scanning will include the channel. When the
channel is deleted from the scanning list, the channel will be skipped
upon scanning. All channels are saved to Memory during manufacture.
To add or remove a channel from the Memory, press and hold the
SCAn/MeM key.

1. CTCSS CODE SELECTION
The Continuous Tone Coded Squelch System (CTCSS) is a Squelch quieting
system that allows groups of users to share the same channel without
disturbing each other. It uses 1 of 38 low frequency tones to open and
close the Squelch on the radio. The CTCSS codes do not prevent others
from hearing your transmission. They simply provide you with a quieter
channel by preventing you from hearing transmissions that are not using
the same code as you and are therefore not directed at you.
note:
To communicate with other UHF radios using CTCSS, all radios
you wish to communicate with must be switched to the same channel
and have the same CTCSS code selected. If you wish to receive
signals from UHF radios that are not using CTCSS you will need to
either disable CTCSS on that channel or set the CTCSS code to '
described in the following 'note'.
