To Lock out a frequency,
quickly press L/OUT while the frequency is displayed.
To Review or Unlock frequencies,
press FUNC then L/OUT and you will see the first locked frequency, the group (gx), and the 1 MHz segment (xxx)(?), and L/Out xxx of xxx in the
display. Press
to step through the locked out frequencies. To unlock a frequency, press CL. Press FUNC then L/OUT to exit.
To Clear All locked out frequencies in All groups,
press FUNC then L/OUT and you will see the lockout list. Press FUNC then 6. Clear entire list? Press 1 to clear all, any other key
aborts appears in the display. Press 1 to unlock all frequencies. List cleared briefly appears in the display then No Lockout. Press FUNC then L/OUT to exit.
Note: You will have to turn the Delay and/or Attenuator back on after clearing the list(??).
To turn the Attenuator on or off for all groups,
press ATT.
To turn the Delay on or off for all groups,
press DELAY.
To Copy a frequency into a channel,
quickly press FUNC then PGM. Then see
Frequency Copy
.
To Copy a frequency into the priority channel,
quickly press FUNC then PRI while the channel is displayed. The display will flash twice and the frequency will be copied into the priority
channel.
To exit
, press

Scanning Conventional Banks
Contents
The scanner won't scan unless frequencies are first programmed into the channels. See
Programming Conventional Frequencies
.
Press SCAN
to start scanning.
Select any combination of banks to scan
by pushing the number keys that correspond to the banks. Numbers appear at the top of the display showing the currently selected banks. Banks that
show . (dots), are turned off. The scanner scans through all the channels in the bank and moves to the next bank. The cursor blinks on the bank number when the scanner scans the channels in
that bank. If the scanner finds an active channel, it stops on it. When the transmission ends, the scanner resumes scanning. If it is a long transmission, (such as a Ham rag chewing) and you want
to move on, press SCAN again to resume scanning. The scanner won't scan channels that are locked out or have 0 as the frequency.
If the scanner picks up an unwanted partial frequency,
turn SQ clockwise to decrease the scanner's sensitivity and mute the scanner so it will continue scanning.
To listen to a weak or distant frequency,
turn SQ counterclockwise to increase the scanner's sensitivity.
To change the scan direction,
press
or
.
To turn banks on or off while scanning,
press the number key, 09 that corresponds with bank you want to turn on or off. You cannot turn off all banks. One bank must always be active.
To Pause on a channel,
quickly press MAN while the channel is displayed. Press SCAN to resume.
To Lock out a channel,
quickly press L/OUT while the channel is displayed. See
Lockingout Channels
.
To turn the Delay on or off for a channel,
quickly press DELAY while the channel is displayed.
To Attenuate a channel,
quickly press ATT while the channel is displayed.
To Store the CTCSS or DCS tone,
quickly press ENT while the tone is displayed. Code Stored briefly appears in the display. See
Programming Tone Codes
.
To
change the Receive Mode
of a channel,
quickly press MODE while the channel is displayed.
To set a channel as the Priority Channel,
quickly press FUNC then PRI while the channel is displayed. See
Priority Scanning
.
To exit scanning,
press MAN.
Changing Receive Modes
The scanner is preset to the most common AM or FM receive mode for each frequency range. The preset mode is correct in most cases. However, some amateur radio transmissions and trunked
systems do not operate in the preset mode. If you try to listen to a transmission when the scanner is not set to the correct receive mode, the transmission might sound weak or distorted. See also
Understanding CTCSS/DCS
.
To change the Receive Mode of a channel,
select the channel in manual mode by entering the bank number and channel number (Ex: 001) then press MAN to advance to the channel. Press
MODE until the desired mode is found.
Note: You cannot change the receive mode of a nontrunked channel to MO, ED or LT.
Or, if the scanner is scanning
and stops on an active channel, quickly press MODE to change the mode.
Using the Attenuator
Contents
To reduce interference or noise caused by strong signals, you can reduce the scanner's sensitivity to these signals. There are two attenuator modes in your scanner. One is normal attenuator
mode in which you set the attenuator for each channel (and channels in search SR02), each search group (in search banks SR3 and SR5), each search band (SR4 and SR6), or a Tune search.
The other is global mode in which applies global attenuation (on or off) to every channel or search regardless of the channel or search attenuation setting.
To turn the Attenuator on or off for a single channel while scanning,
quickly press ATT while the channel is displayed or select the channel in manual mode by entering the bank number and
channel number (Ex: 001) then press MAN to advance to the channel. Press ATT. att turns to ATT in the display when the channel is attenuated.
To turn the Attenuator on or off for Search,
press ATT during the search. att turns to ATT in the display when the search is attenuated.
To toggle the Global Attenuator Mode on or off,
while searching or scanning, press FUNC then ATT.
To toggle Global Attenuation on or Global Attenuation off,
Press ATT while Global Attenuator Mode is active.
ATG appears in the display when global attenuation is on for all channels/searches.
atg appears in the display when global attenuation is off for all channels/searches.

Priority Scanning
You can program one additional conventional frequency, a stored conventional channel, or a weather channel as a priority channel. The Priority feature lets you scan through the channels and
still not miss important or interesting calls on a specific frequency. When a channel is selected as the priority channel and priority is turned on, the scanner checks that channel or frequency every
2 seconds, and stays on the channel if there is activity until the activity stops even if the bank for the channel is turned off. The priority feature also works in Search and Manual modes.
The Priority feature does not work properly while trunking an EDACS or Motorola system. (It may seem to work at first but will jump off IDs when the feature checks the priority channel while
receiving certain trunked transmissions, especially EDACS, if you can tolerate that. Or, it will not check the priority channel at all during some trunked transmissions).
To Program a channel as the priority channel in manual mode,
enter the bank number and channel number then press MAN to advance to the channel. Press FUNC then PRI. You will see
Priority Channel blink twice on the bottom line.
Note: You cannot program a channel which has a receive mode of MO or ED as the priority channel.
To Program a channel when the scanner is scanning
and stops on an active channel, quickly press FUNC then PRI before it continues scanning again. You will see Priority Channel blink twice
on the bottom line.
To Program a frequency as the priority channel,
in manual mode, press PGM then PRI. Enter the frequency you want to use as the priority channel then press ENT.
To Program a Weather Channel as the priority channel,
press WX. Select the weather channel you want to use as the priority channel then press FUNC and PRI. You will see Priority Channel
blink twice on the bottom line. Press MAN or SCAN to exit. If you program a weather channel as the priority channel, the scanner goes to the priority channel only when the scanner detects the
weather alert tone. See
Receiving SAME Weather Alerts
.
To turn on the Priority Feature,
press PRI. When the priority channel is active, Pch will appear on the top line to the left of the channel or frequency.
PRIon appears in the top line if a AM or FM channel is programmed as the priority channel.
PRIct appears in the top line if a channel in CT mode is programmed as the priority channel.
PRIdc appears in the top line if a channel in DC mode is programmed as the priority channel.
PRIwx appears in the top line if a weather channel is programmed as the priority channel.
To turn off the Priority Feature,
press PRI.
Locking/Unlocking Channels
You can keep the scanner scanning by locking out channels that have a continuous transmission (such as a weather channel).
To Lock or Unlock a channel,
select the channel by entering the bank number and channel number (Ex: 001) then press MANUAL to advance to the channel. Press L/OUT. lo changes to LO in
the display if the channel is locked out.
To Lock out a Channel if the scanner is scanning
and stops on the channel, quickly press L/OUT before it continues scanning again. The scanner will lock out the channel and automatically
resume scanning.
