BEFORE YOU BEGIN
Battery Pack Installation and Removal
To install the battery, hold the transceiver with
your left hand, so your palm is over the speaker
and your thumb is on the top of the belt clip. Care-
fully mate the battery’s four insertion slots with
their corresponding alignment tabs on the trans-
ceiver case, while tilting the Belt Clip outward.
Proper alignment occurs with the battery pack
offset about 1/2 inch from the top edge of the bat-
tery compartment.
Guide the pack on to the tabs with a slight inward
pressure, then slide the battery pack upward, un-
til it locks in place with a “Click.”
To remove the battery, turn the radio off and re-
move any protective cases. Slide the Battery Pack
Latch on the bottom of the radio toward the front
panel while sliding the battery down about 1/2
inch. Then lift the battery out from the radio while
unfolding the Belt Clip.

able Lithium-Ion packs, as they could ex-
plode if accidentally short-circuited.
Low Battery Indication
As the battery discharges during use, the voltage
gradually becomes lower. When the battery voltage
becomes to low, substitute a freshly charged battery
and recharge the depleted pack. The LED indicator
on the top of the radio will blink red when the bat-
tery voltage is low.
Caution
Danger of explosion if battery is replaced with
an incorrect battery. Replace only with the same
or equivalent type.

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
“*ERROR *” 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.

FOLLOW-MESCAN
The “Follow-Me” Scan feature checks a User-as-
signed Priority 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 “Follow-Me” scanning, first select the

Priority Channel” and press the assigned program-
mable key, or set the toggle switch to the assigned
position. Then rotate the CH Selector knob to recall
to the “Scanning Start” channel which has been pro-
grammed by your dealer to activate the scanner. When
the scanner stops on an “Active” channel, the User-
assigned Priority Channel will automatically be
checked every few seconds; if activity is found on
the User-assigned Priority Channel, the radio will
switch between it and the Dealer-Assigned Priority
Channel, if any.
FOLLOW-MEDUAL WATCH
To set up a “Dual Watch” frequency pair using the
“Follow-Me” feature, select a channel using the CH
Selector knob. Now press the assigned programmable
key; pressing the assigned programmable key locks
the current channel as the User-assigned Priority
Channel. Now rotate the CH Selector knob to select
another channel (not the “Scanning Start” channel).
