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 20.
Continuous Tone Coded Squelch System
Selective squelch opening by sub-tone detection (CTCSS) can be enabled,
using the configuration mode (see CTCSS on page 23). Please note that if
the radio is operating with CTCSS on a channel, and a carrier is received,
it may not be recognized in the loud speaker if the matching sub-tone is
not detected. For this reason, be very careful not to use CTCSS
programmed channels in emergency situations. For the same reason
transmitting is prohibited (reporting "BUSY") if a (silent) carrier
containing any sub-tone is active on the channel while pressing PTT
.
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.
