2) When you press the PTT switch on the
Speaker/Microphone, it disables the internal mi-
crophone, and vice versa.
If the Busy Channel Lockout feature has been
programmed on a channel, the radio will not trans-
mit when a carrier is present. Instead, the radio
will generate short beep three times and indicate
“*CH Busy *” on the display (16-key and 4-
key versions). Release the PTT switch and wait
for the channel to be clear of activity.
If CTCSS or Digital Coded Squelch (DCS) Lock-
out has been programmed on a channel, the radio
can transmit only when there is no carrier being
received or when the carrier being received in-
cludes the correct CTCSS tone or DCS code.
Automatic Time-Out Timer
If the selected channel has been programmed for au-
tomatic time-out, you must limit the length of each
transmission. While transmitting, a beep will sound
10 seconds before time-out. Another beep will sound
just before the deadline; the “TX” indicator will dis-
appear and transmission will cease soon thereafter.
To resume transmitting, you must release the PTT
switch and wait for the “penalty timer” to expire.

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 sta-
tion and talk directly to a station that is nearby. This
feature has no effect when you are operating on “sim-
plex” channels, where the receive and transmit fre-
quencies are already the same.
When the “TA” function is activated, the “ ” icon
will be indicated on the display.
Note that your dealer may have mode provision for
“Talk Around” channels by programming “repeater”
and “Talk Around” frequencies on two adjacent chan-
nels. If so, the key may be used for one of the other

TX SAV E DISABLE
Press 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 reducing transmit power when a very strong sig-
nal from an apparently nearby station is being re-
ceived. 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 necessary at all times.
ENCRYPTION
Press the assigned Programmable key to toggle the
Encryption feature “On” and “Off.”
FM SCAN
The FM Scan feature checks a User-assigned Prior-
ity Channel regularly as you scan other channels.
Thus, if only Channels 1, 3, and 5 (of the 8 available
channels) are designated for “Scanning,” the user may
nonetheless assign Channel 2 as the “User-assigned”
Priority Channel via the “Follow-Me” feature.
To activate FM Scan, first select the channel you want
to designate as the “User-Assigned Priority Chan-
nel” and press the assigned programmable key. Then
rotate the CH Selector knob to recall to the “Scan-
ning Start” channel which has been programmed by
your dealer to activate the scanner. When the scan-
ner stops on an “Active” channel, the User-assigned
Priority Channel will automatically be checked ev-
ery few seconds; if activity is found on the User-as-
signed Priority Channel, the radio will switch between
it and the Dealer-Assigned Priority Channel, if any.
