FEATURES
Thank you for purchasing the
RadioShack 22ch GMRS/FRS Base
Station. Your radio is a new two-way,
short-range voice radio service that lets
families and groups keep in touch with
each other on specific reserved
channels. You can place it on a
desktop surface or mount it on a wall in
your home or office.
Your radio has 22 channels and 38
different quiet codes, which you can
use to talk with another person who has
a General Mobile Radio Service
(GMRS) or Family Radio Service (FRS)
radio set to the same frequencyas your
radio. !
Your radio has auto-squelch, so you
will not hear anything on a channel
unless someone is transmitting nearby
on the same channel. You can turn off
auto-squelch by pressing down MON to
hear weaker, distant transmissions.

The FCC Wants
You to Know
This equipment has
been tested and found
to comply with the limits
for a Class B digital
device, pursuant to Part
15 of the FCC Rules.
These limits are
designed to provide
reasonable protection
against harmful
interference in a
residential installation.
This equipment
generates, uses and
can radiate radio
frequency energy and, if
not installed and used in
accordance with the
instructions, may cause
harmful interference to
radio communications.
However, there is no
guarantee that
interference will not
occur in a particular
installation.
If this equipment does
cause harmful
interference to radio or
television reception,

Preparation
PREPARATION
SELECTING ALOCATION
Select a location for the base station
that is:
•NearanACoutlet
• Out of the way of normal activities
• Not likely to get wet
• Away from electrical machinery,
electrical appliances, and metal
walls or filing cabinets
• Away from wireless intercoms,
alarms, and room monitors
The location of the base station affects
its range. If you have a choice of
several locations, test each to see
which provides the best performance.
USING AC POWER
Power the radio using the supplied 6V,
500 mA AC adapter.
Your radio is UL listed to ETL
standards and meets all applicable
FCC requirements.
(Continued) which can
be determined by
turning the equipment
off and on, the user is
encouraged to try to
correct the interference
by one or more of the
following measures:
• Reorient or relocate
the receiving
antenna.
• Increase the
separation between
the equipment and
receiver.
• Connect the
equipment into an
outlet on a circuit
different from that to
which the receiver is
connected.
• Consult your local
RadioShack store or
an experienced
radio/TV technician
for help.
• If you cannot
eliminate the
interference, the
FCC requires that
you stop using your
radio. (Continued
)

Cautions:
You must use a Class 2
power source that
supplies 6V DC and
delivers at least 500 mA. Its center
tip must be set to positive and its
plug must fit the radio's DC 6V 500
mA jack. The supplied adapter
meets these specifications. Using
an adapter that does not meet
these specifications could damage
the radio or the adapter.
WARNING: To reduce the risk of fire or shock hazard, do not
expose this product to rain or moisture.
CAUTION
RISK OF ELECTRIC
SHOCK. DO NOT
OPEN.
CAUTION: TO REDUCE THE RISK OF ELECTRIC SHOCK,
DO NOT REMOVE COVER OR BACK. NO USER-SERVICEABLE
PARTS INSIDE. REFER SERVICING TO QUALIFIED
PERSONNEL.
This symbol is intended to alert you to the
presence of uninsulated dangerous voltage
within the product’s enclosure that might be of
sufficient magnitude to constitute a risk of
electric shock. Do not open the product’s case.
This symbol is intended to inform you that
important operating and maintenance
instructions are included in the literature
accompanying this product.
(Continued) Changes
or modifications not
expressly approved by
RadioShack may cause
interference and void
the user’s authority to
operate the equipment.
Your radio might cause
TV or radio interference
even when it is
operating properly. To
determine whether your
radio is causing the
interference, turn off
your radio. If the
interference goes away,
your radio is causing it.
Try to eliminate the
interference by:
• moving your radio
away from the
receiver
• connecting your
radio to an outlet that
is on a different
electrical circuit from
the receiver
• contacting your local
RadioShack store for
help (Continued

1. Insert the
supplied
adapter’s
barrel
plug into
the DC 6V
500mA
jack on the back of the radio.
2. Route the adapter cord into the
groove on the back of the radio.
3. Plug the adapter into a standard
AC outlet.
4. Raise the antenna to a vertical
position.
MOUNTING ON AWALL
1. Drill two holes 23/4-inches apart.
Then thread a screw into each
hole, letting the screw heads
extend about 1/8-inch from the
wall. Ô
(Continued)Ifyou
cannot eliminate the
interference, the FCC
requires that you stop
using your radio.
This device complies
withPart15oftheFCC
Rules. Operation is
subject to the following
two conditions: (1) this
device may not cause
harmful interference,
and (2) this device must
accept any interference
received, including
interference that may
cause undesired
operation.
ÔNOTE Ô
To mount the radio on a
wall, you need two
screws (not supplied,
available at your local
RadioShack store) with
heads that fit the
keyhole slots on the
bottom of the radio. 23/4-in Strain

2. Insert the supplied adapter’s barrel
plug into the DC 6V 500mA jack on
the back of the radio.
3. Route the adapter’s cord into the
strain relief groove on the back of
the radio, then plug the adapter
into a standard AC outlet.
4. Place the radio’s two keyhole slots
over the screws and slide the unit
down to secure it.
5. Raise the antenna to a vertical
position.
OPERATION
Rotate VOLUME to turn on/off the radio
andtoadjustthevolume.
SELECTING ACHANNEL
To manually select a channel, press
e/SCAN or d/CALL.Theselected
channel number appears. See
“Transmit Frequencies and Power” on
Page 8.
To scan through the channels, hold
down e/SCAN until SCAN appears. The
radio automatically scans through the
channels and pauses on each active
channel. BUSY appears when a call is

USING QUIET CODES
Quiet Codes let you talk and listen to
other radios set to the same channel
and CTCSS(quiet code). This is similar
to having a sub-channel within a
channel, giving you greater
communication flexibility. When you set
a quiet code (there are 38 codes to
choose from) and turn on this feature,
you can communicate with any user
whohasaradiosettothesame
channel and quiet code.
1. Hold down QUIET until the quiet
code flashes.
2. Repeatedly press e/SCAN or
d/CALL until you see the desired
quietcode.(See“QuietCodes”on
Page 10 for a complete list of quiet
codes.) Ô
3. Press QUIET to store the quiet
code.
4. To turn off the quiet code feature,
press QUIET.Thequietcode
disappears.
ÔNOTE Ô
• To quickly find a
quiet code, hold
down d/CALL until
the desired quiet
code appears, then
release d/CALL.
• We recommend that
you select a quiet
code from the range
7–30. If you select a
code below or above
that range, you must
wait 1 to 2 seconds
after holding down
TALK before you
start talking.

normal voice. ¬ appears. When you finish speaking, release
TALK.
USING CALL
Hold down CALL to send a page to other GMRS/FRS radios set
to the same channel (and quiet code, if you selected one). ¬
