Programming Tips
• Do not program a weather frequency into one of the channels, since weather channels
transmit continuously. Use the Weather Search feature to select the weather information band.
• Group similar services into a bank. For example, program police frequencies in channels 1
through 10 and fire/emergency into channels 51 through 60, and so on.
• Put the frequency that you listen to the most or the most important frequency into a
Priority channel.
• To quickly program a series of channels, start with the lowest number channel.
For example, when you are programming five new frequencies into Channels 4 through
8, start with Channel 4. After you finish programming a channel, press MAN or HOLD/s
to go to the next higher channel.
• Write down your programmed channels and frequencies and put in a convenient place in
case of accidental reprogramming.
• If you want to download frequencies using the SmartScan feature, go to page 59
in this manual.
• Frequencies are rounded off according to the step of each channel.
• When you are overwriting a tagged channel with a new frequency, the previous alpha tag
will be deleted. You must re-enter the alpha tag.
• When programming frequencies, a 2 second delay is set automatically but can be changed
in the Channel Data menu.
Deleting a Stored Frequency
To delete a stored frequency:
a. Select a channel.
b. Press 0.
c. Then press E.

Squelch (SQ) Mode
The scanner can be set to the following SQ modes.
• Carrier SQ mode (default setting)
The scanner will stop on any transmission or squelch opening, regardless of whether any
sub-audible tone has been programmed for the channel or search range.
• Tone SQ mode
The scanner will stop on any active frequency for which either no sub-audible tone has
been programmed or for which the user-programmed sub-audible tone is also active.
• Tone Search mode
During any transmission, the scanner will begin searching all possible sub-audible tones,
one of which may also be in use. The scanner counts up through the CTCSS tones and
instantly determines any possible DCS tone. See Page 83 for a listing of the tones that the
