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. Carefully
mate the battery’s four insertion slots with their
corresponding alignment tabs on the transceiver
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 battery com-
partment.
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 un-
folding the Belt Clip.
Do not attempt to open any of the re-
chargeable Lithium-Ion packs, as they
could explode 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 battery
voltage is low.
Caution
Danger of explosion if battery is replaced with
an incorrect battery. Replace only with the same
or equivalent type.
Tilt the Belt Clip
Insert the Battery Pack

If a Speaker/Microphone is available, remove the
plastic cap and its two mounting screws from the
right side of the transceiver, then align the con-
nector of the Speaker/Microphone on the trans-
ceiver body; secure the connector pin using the
screws supplied with the Speaker/Microphone.
Hold the speaker grille up next to your ear while
receiving. To transmit, press the PTT switch on
the Speaker/Microphone, just as you would on the
main transceiver’s body, and speak into the mi-
crophone on a normal voice level.
Note 1): Save the original plastic cap and its
mounting screws. They should be reinstalled
when not using the Speaker/Microphone.
2) When you press the PTT switch on the
Speaker/Microphone, it disables the internal
microphone, 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
automatic 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.

FOLLOW-ME SCAN
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
channel you want to designate as the “User-Assigned
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-ME DUAL 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).
Your radio will now switch back-and-forth between
the currently-selected channel and the User-assigned
Priority Channel.
During “Follow-Me” scanning (after you have
pressed the key), you can set up the “Dual Watch”
feature by rotating the CH Selector knob to another
channel. The radio will then scan back and forth be-
tween the original User-assigned Priority Channel and
the newly-selected channel.
The Priority Channel you have assigned (before
pressing the key) will be retained in memory until
you change it.
