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, 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.
The device complies with Part 15 of the FCC 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.
SAFETY INFORMATION
Your wireless handheld portable transceiver contains a low power
transmitter. When the Push-To-Talk (PTT) button is pressed, it sends out
radio frequency signals. The device is authorized to operate at a duty factor
not to exceed fifty percent. In August 1996, the Federal Communications
Commission adopted RF exposure guidelines with safety levels for handheld
wireless devices.
CAUTION
To maintain compliance with the FCC’s RF exposure guidelines, hold the
transmitter and antenna at least two inches from your face and speak in a
normal voice, with the antenna pointed up and away from your face. If you
wear the handset on your body while using the headset accessory, use only
the supplied belt clip for this product. When transmitting, take it out of the
belt to ensure the antenna is at least one inch (2.5cm) from your body.
Use only the supplied antenna. Unauthorized antennas, modifications, or
attachments could damage the transmitter and may violate FCC regulations.

NOTE: When you are finished configuring the current setting, press MENU
again to confirm and move to the next setting. To confirm the changes but
quit the Menu Options, press PTT.
Selecting a Channel
Select between the 14 channels of the transceiver to use to communicate
with others. To transmit, the transmitter and the receiver must be on the same
channel.
Scanning
When you are selecting a channel, you can also activate the channel scan
function by pressing and holding
or . will be shown on the
display. If a valid signal is present, the transceiver will pause on the current
active channel. Press a button to set this as your channel. Otherwise, the
scan mode will then immediately search for the next channel if no button is
pressed after 5 seconds. During scan, pressing PTT or MENU key will stop
the scan mode and exit the menu. Or, pressing MENU key will stop scan-
ning and go to the next setting.
Selecting a CTCSS code
The CTCSS is like having a sub-channel within a channel, giving you greater
communication flexibility. It lets you talk and listen to other transmitters set
to BOTH the same channel and CTCSS code. There are 38 CTCSS codes
to choose from (see Appendix).
Scanning the CTCSS
You can also activate the CTCSS scan function by pressing and holding
or . will be shown on the display. If a valid signal is present, the
transceiver will pause on the current active CTCSS channel. Press a button
to set this as your CTCSS channel. Otherwise, the scan mode will then
immediately search for the next CTCSS channel if no button is pressed after
5 seconds. During scan, pressing PTT or MENU key will stop the scan
mode and exit the menu. Or, pressing MENU key will stop scanning and go
to the next setting.
Setting VOX
This setting automatically detects and transmits your voice through the se-
lected channel, without needing to push and hold PTT. Select between 3
levels of VOX by pressing
or key. The icon
is displayed when
this function is enabled.
LCD Symbol Description
0 VOX disabled
1 Low sensitivity – only audibly loud voices are
transmitted (useful for noisy environment)
2 Normal sensitivity – ideal setting for voice-
activated transmission
3 High sensitivity – all detected sounds (includ
ing noise) are transmitted
Roger Beep Mode
If the Roger Beep mode is enabled, the receiving party will hear a beep tone
when you finish transmitting a message. This avoids situations where mes-
sages are interrupted because the other party is not aware that the transmis-
sion is not finished. Press
or to activate or deactivate the Roger Beep
function. Icon
will be shown if activated.
Key Tone
The Key Tone function, if enabled, causes the unit to beep whenever a
button is pressed. Press
or to activate or deactivate the Key Tone
function. Icon ‘
’ will be shown if activated.
APO Function (Automatic Power Off)
This function enables your transceiver to automatically shut itself off if left
idle for 2 hours. Press
or key to activate or deactivate the APO func-
tion. Icon
will be shown if activated.
NOTE: To re-enable the transceiver after automatic shut-off, simply press
PWR button.
CHARGING CONTACTS
(OPTIONAL)
You can directly charge Ni-MH re-
chargeable batteries without taking bat-
teries out from the battery compartment
by using an optional 2-bay cradle charger
(sold separately). You can recharge up
to two radios at the same time. The LED
on the cradle charger will light red when
the transceivers are charging. Complete
charging takes about 14 to 1 6 hours.
Located inside the transceiver’s battery
compartment is a charging switch, which
enables the recharging of batteries. When
placed on the cradle. The switch must be
set to ‘ON’ when rechargeable batteries are used and recharged using the
cradle. If alkaline batteries are used, the switch should be set to ‘OFF’.
WARNING: Do not put transceivers into the charger when using alkaline
batteries.
CAUTION: The cradle charger does not automatically switch off after the
batteries have been fully recharged. As such, there is a danger of over-
charging, which may shorten the batteries’ lifespan heavily.
