Programming the scanning memory
To add a channel to the scanning memory, select the channel and then
press and hold the SCN key until the display shows MEM at the top.
To remove a channel from the scanning memory, select the channel and
then press and hold the SCN key until the MEM sign disappears from the
display.
Low power operation
The radio can be operated in low power mode. In this mode battery life
time is dramatically increased. Up to the first second of a received call
might be lost if this mode is selected. Refer to
SLEEP on page 18.
Continuous Tone Coded Squelch System
On channels where it is allowed, you can set up selective squelch
opening by sub-tone detection (CTCSS), using the configuration mode
(see
CTCSS on page 21). Please note that if the radio is operating with
CTCSS on a channel, it is impossible to receive a normal signal on that
channel. For this reason, be very careful not to use CTCSS programmed
channels in emergency situations. Channels programmed with CTCSS will
have a clear identification in the service field, e.g. "CTCSS 22", while
selected. Not all channels are allowed for CTCSS use.
For maritime channels CTCSS is automatically disabled when
•Product is turned off
• A new channel is selected
For private channels, the feature will remain until manually removed.
