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 channelby 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 12.5kHz 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 storedin 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.
. If you want to manua~y er~e all the
.
memory, fIrst turn off the scanner.
Then, press and hold. MANUAL,(]), and CD simultaneously while you turn
the scanner back on. The channel display shows IILI!, and all memory is
erased.
