Scanning
Scanning sequentially checks all saved
channels for activity. You must save
frequencies into channels to scan. The scanner
does not scan empty channels or unsaved
frequencies.
You can increase the scanning speed by
locking out channels with continuous
transmissions, such as a weather channel, or
turning off entire banks. Turning off a bank
prevents the scanner from scanning any
channels within the bank. You cannot turn off
all banks. There must be at least one active
bank to scan.
To scan:
1. Press
SCAN. The scanner checks all
unlocked channels in the active banks. To
change the scan direction, press S or T.
2. To stop on a channel, press PSE.
3. To lock out a channel, when the scanner
stops on the channel, press L/OUT.
4. To turn off a bank, press the bank’s
number so the bank’s number disappears.
To turn on a bank, press the number key
so the bank’s number appears.
Locking Out Channels
You can increase the scanning speed by
locking out channels with continuous
transmissions.
To lock out a channel:
1. Press
MAN.
2. Enter the bank and channel number or
use S or T to select the channel.
3. Press L/OUT.
“lo”
changes to
“LO.”
4. To unlock a locked-out channel, press
L/OUT again.
To review all locked out channels:
1. Press
MAN.
2. Repeatedly pressing FUNC and then
L/OUT to view each locked-out channel.
3. To unlock a channel, press L/OUT.
“LO”
changes to
“lo.”
4. When you finish reviewing locked-out
channels, press MAN.
Note:
You can manually select any
channel in a bank, even in turned-off
banks.
Priority Scanning
In addition to the 1,000 programmable
memory channels, your scanner has one
Priority channel. When Priority is turned on,
the scanner checks the Priority channel every 2
seconds. This lets you scan without missing a
transmission on the Priority channel.
Note:
Priority scanning does not
operate for trunking transmissions.
Priority check can seem random during
peak hours.
