Adjusting the Squelch

Open the squelch by turning SQUELCHclockwise to position 8 or 9. You should hear a steady sound

~\ (scanning stops).

Now turn SQUELCHcounterclockwise slowly until the sound disappears. This is the threshold point at which scanning starts. At the squelch threshold, an incoming signal just slightly stronger than the noise will open the squelch.

When squelch is open, you can hear the broadcast (scanning is stopped). If squelch is set too tight (that is, too far counterclockwise from the threshold point), a stronger signal is required to open the squelch.

If squelch is set on a point clockwise from the threshold, you hear a constant sound (noise, if no signal is present); the scanner does not scan.

Programming Tips

You can program 1 frequency per channel.

. Channel! is the fixed priority channel. Program the most important frequency, or the one of major interest, into Channel!.

.

.

To quickly program a series of channels, start programming at the lowest number channel you want to program. For example, when you program five new frequencies into Channels 4 through 8, start with Channel 4. After you

complete the programming in 1 channel by pressing ~, press~ to step up to the next channel to be programmed.

If you make an error during programming, or the frequency is out of range,

IIEIIappears on the channel display.

.

During numeric entry, if you know that you pressed the wrong number,

 

press ~

twice. This cancels the entire numeric entry, and displays the

 

current channel number.

.

Above 406 MHz, the frequency steps are in 12.5 kHz increments. To enter

 

a frequency such as 450.4875, press each key in sequence. You will not

 

see the last digit entered in the display (even when reviewed). However, the

 

correct frequency is stored in the scanner.

.

Once you have programmed a channel, you cannot erase the frequency in

 

that channel. . However, you can change the frequency in a specific channel

.

by programming a new frequency over the existing one.
