Mxx The memory number displayed before the
arrow is the first channel of the block of memories to be
scanned. Pressing the
wheel to modify this (spin-wheel legend is From).
Mxx The memory number displayed after the arrow
is the last channel of the block of memories to be scanned.
Pressing the soft-key allows the spin-wheel to
modify this (spin-wheel legend is To).
SQUELCH Sets the minimum signal level that will
stop the scan (if HOLD is enabled) or unmute the audio
(if MUTE is enabled). When the scan is active the squelch
level will be recalled from each memory channel as it is
monitored. If the squelch level is changed with the spin-
wheel then the new value will be stored back into the
memory automatically.
SCAN The soft-key legend Scan is followed by a
bullet which indicates if scanning is active. If the bullet is
filled (i.e. scanning enabled) then the receiver will switch
to the next channel when the delay and hold conditions
permit. The soft-key toggles scanning on and off -
additionally scanning will be turned off if menus other than
SCAN or SCAN SETUP or the S-meter are selected on
the display. Pressing

MUTE The soft-key legend Mut is followed by a
bullet. If the bullet is filled (i.e. muting enabled) then audio
will be silenced when squelch is active (reversed
S displayed). The

EXCLUDE The soft-key legend Excl is followed
by a bullet. If the bullet is filled (i.e. memory channel
excluded) then this memory will not be checked during
the scanning cycle. The first channel in the block of
memories to be scanned will not be excluded, even if it is
so marked. The soft-key toggles exclude on and
off for the currently selected memory channel.

Note: It is possible to use the infrared controller
key to manually advance the scan to the next channel,
but this does not check for excluded memories or for the
end of the scan block (it just recalls the next memory as
the key normally does). It is possible to jump
outside of the scan loop by using this key and left to its
own devices the receiver will work round all of the
memories until it returns to the loop. If this occurs it can
be simply fixed by pressing the
Example: To scan memory channels from 5 to 9 with
memory 8 excluded. It is assumed that useful frequencies
have been stored in these memories. In this example the
frequencies are all intermittent communication channels,
so the receiver is set to stop and monitor a channel when
it finds a signal:-

and make sure that the bullet after Excl is not filled.
Press the soft-key if necessary.
Step through each memory up to 9 using the spin-
wheel making sure that none are excluded, except
for number 8 which we want to omit from the scan.
2. Select the SCAN SETUP menu - use the

the scanning memory block.
If the start channel number Mxx is not set to 5 then
press the soft-key and use the spin-wheel to
set the block start to 5. The legend From will appear
over the spin-wheel indicating that the block start is
being changed.
If the stop channel number Mxx is not set to 9 then
press the soft-key and use the spin-wheel to
set the block end to 9. The legend To will appear over
the spin-wheel indicating that the block end is being
changed.
3. Press the soft-key (if Dly is not above the spin
wheel) and then use the spin-wheel to set the scan
delay to 5.0s - the value is displayed at the top left of
the LCD.
Make sure that the Hold bullet is turned on (press the
soft-key if necessary).
Note: This scan speed (5 seconds delay) is rather
slow for the present application, but it will be easy to
see what is happening, and it will also be possible to
adjust the squelch levels while the scan is running.
Once everything is set the scan delay can be reduced
to about 1 second for this example.
