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.

ARTSTM (AUTO RANGE TRANSPOND SYSTEM)
This system is designed to inform you when you and
another ARTSTM-equipped station are within com-
munication range.
During ARTSTM operation, when the radio receives
the correct ARTSTM signal, a short beep will sound
and the “In” (meaning “In Service”) notation will be
displayed on the sub-LCD. If you move out of range
for more than two minutes, your radio senses that no
signal has been received; three short beeps will sound,
and “Out” (“Out of Service”) will be displayed on
the sub-LCD. If you subsequently move back into
range, as soon as the other station transmits, a short
beep will sound and “In” will be displayed again on
the sub-LCD.
: Except on Non-LCD version.
DTMF PAGING SYSTEM
This system allows paging and selective calling, us-
ing DTMF tone sequences.
When your radio is paged by a station bearing a tone
sequence which matches yours, your radio’s squelch
will open and the alert will sound. The three-digit
code of the station which paged you will be displayed
on your radio’s LCD.
