Talk Around
Press (or Press and hold) the assigned
Programmable
key to
activate the Talk Around feature when you are operating on du-
plex channel systems (separate receive and transmit frequencies,
utilizing a “repeater” station). The Talk Around feature allows
you to bypass the repeater station and talk directly to a station
that is nearby. This feature has no effect when you are operating
on “Simplex” channels, where the receive and transmit frequen-
cies are already the same.
When the “TA” function is activated, the “
” icon will be indi-
cated on the display.
Note that your dealer may have made provision for “Talk Around”
channels by programming “repeater” and “Talk Around” frequen-
cies on two adjacent channels. If so, the key may be used for one
of the other Pre-Programmed Functions.
Add/Del
The Add/Del feature allows the user to arrange a custom Scan.
Press (or Press and hold) the assigned
Programmable
key to
delete/restore the current channel to/from your scanning list.

-SKIP-
” will appear on the
LCD for one second after pressing the
Programmable
key.
When you restore a current channel, “
-STOP-
” will appear on the
LCD for one second after pressing the
Programmable
key.

Your Dealer may have pre-programmed Auto-Dial telephone
number memories into your radio.
To dial a number, press (or Press and hold) the Dealer-assigned
Programmable
key for Speed Dialing, then press the number
key (0 - 9) corresponding to the telephone number memory you
wish to send. The DTMF tones sent during the dialing sequence
will be heard in the speaker.
TX Save Off
Press (or Press and hold) the assigned
Programmable
key to
disable the Transmit Battery Saver, if you are operating in a lo-
cation where high power is almost always needed.
The Transmit Battery Saver helps extend battery life by reduc-
ing transmit power when a very strong signal from an apparently
nearby station is being received. Under some circumstances,
though, your hand-held radio may not be heard well at the other
end of the communication path, and high power may be neces-
sary at all times.

Programmable
key to
disable the Noise and Tone squelch. Again press (or Press and
hold) the assigned
Soft
key to resume normal (quiet) Noise and
Tone squelch action.
Low Power
Press (or Press and hold) the assigned
Programmable
key to
set the radio’s transmitter to the “Low Power” mode, thus ex-
tending battery life. Press (or Press and hold) the assigned
Pro-
grammable
key again to return to “High Power” operation when

check each channel for the presence of a signal, and will stop on
a channel if a signal is present.
To activate scanning:
Press (or Press and hold) the assigned
Programmable
key.
The scanner will search the channels, looking for active ones;
it will pause each time it finds a channel on which someone is
speaking.
To stop scanning:
Press (or Press and hold) the assigned
Programmable
key.
Operation will revert to the channel to which the
CH
knob is
set.
Follow-Me Scan
“Follow-Me” Scan feature checks a
User-assigned
Priority Chan-
nel regularly as you scan the other channels. Thus, if only Chan-
nels 1, 3, and 5 (of the 8 available channels) are designated for
“Scanning,” the user may nonetheless assign Channel as the
“User-assigned” Priority Channel via the “Follow-Me” feature.
Press the assigned
Programmable
key to activate “Follow-Me”
scanning, then turn the
CH
selector knob to the channel which
you want to designate as the “User-Assigned Priority Channel”.
When the scanner stops on an “active” channel, the User-assigned
Priority Channel will automatically be checked every few sec-
onds.
Dual Watch
The Dual Watch feature is similar to the Scan feature, except
that only two channels are monitored: the current operating chan-
nel, and the “Priority” channel.
To activate Dual Watch:
Press (or Press and hold) the assigned
Programmable
key.
The scanner will search the two channels; it will pause each
time it finds a channel on which someone is speaking.
To stop Dual Watch:
Press (or Press and hold) the assigned
Programmable
key.
Operation will revert to the channel to which the
CH
knob is set.
