Scanning the Stored Channels
Press SCAN/MAN until SCAN appears to continuously
scan through all channels with stored frequencies.
If the scanner finds an active frequency, it stops and
displays that channel and frequency number, then
it automatically begins scanning again when the
transmission on that frequency ends.
n
Notes:
• Press e or d to reverse the scanning direction.
• Press •/DELAY to set the scanner to remain on
the current channel for two seconds after the
transmission ends.
• To set the scanner to remain on the current channel,
even after the transmission stops, press SCAN/
MAN at any time during the transmission so MAN
appears and SCAN disappears (see “Monitoring a
Stored Channel” below).
• Press L/O to lock-out a channel.
Turning Channel-Storage Banks On and Off
To turn a channel-storage bank on or off, press the
bank’s number key (1–0, using 0 for bank 10) during
scanning. The channel-storage banks are on when
they have a bar underneath them and off when no bar
appears underneath them.
n
Notes:
• The scanner does not scan any of the channels
within the banks you have turned off.
• You cannot turn off all banks; there must be at least
one active bank.
• You can manually select any channel in a bank, even
if the bank is turned off.
• When you turn on a bank during scanning, the
scanner moves to the selected bank and scans it.
• If no transmission is found, the scanner continues to
scan through all selected banks.
Monitoring a Stored Channel
You can continuously monitor a specific channel without
scanning. This could be useful if you hear a transmission
on a channel and do not want to miss any details, even
though there might be periods of silence.
1. Press SCAN/MAN until MAN appears.
2. Enter the channel number (1–200).
. Press SCAN/MAN again.
Clearing a Stored Channel
To remove a frequency stored in a channel.
1. Press SCAN/MAN to stop scanning.
2. Press the number keys to enter the channel number
(1–200).
. Press PGM. PGM appears.
4. Press 0 then ENT. The frequency number changes
to 000.000
0
to indicate the channel is cleared.
. To clear another channel, use the number keys to
enter that channel number then press PGM again.
Or, repeatedly press PGM until the desired channel
number appears. Repeat Step 4.
Listening to the Marine Bank
Press to search the marine bank. MAr appears about
two seconds, then the scanner starts searching from
marine channel 16. To change the search direction,
press e or d.
Press PSE to stop searching. SRCH disappears and
MAN
appears.
• To change the channel manually, press e or d.
• To select a channel directly, enter the two-digit
channel number. See “Marine Service Bank” on page 6
for a list of channels.
• To lock-out a frequency, press L/O.
Press PSE again to restart the marine bank search.
