INFORMATION ON SAFE OPERATION
Please read this information before installing or using your UHF radio.
The operation of your UHF radio in Australia is subject to conditions in the
following Licence: In Australia the ACMA Radio communications (Citizen Band
Radio Stations) and in New Zealand by MED the General User Radio Licence for
Citizen Band Radio.
SAFETY AND GENERAL USE WHILST IN A VEHICLE
Check the State and Federal laws and regulations regarding the use of two way
radios in the area where you drive, and always obey them.
FOR VEHICLES FITTED WITH AIRBAGS
When using the radio in a vehicle, do not place your radio in the area over an
airbag, or in the airbag deployment area. Airbags inate with great force, if a
radio is placed in the airbag deployment area and the air bag inates, it may be
propelled with great force and cause serious injury to the occupants of the vehicle.
POTENTIALLY EXPLOSIVE ATMOSPHERES
Turn your radio OFF when in any area with a potentially explosive atmosphere.
Sparks in such areas could cause an explosion or re resulting in injury or even
death. NOTE: Areas with potentially explosive atmospheres are often, but not
always clearly marked. They include fueling areas such as below deck on boats;
fuel or chemical transfer or storage facilities; areas where the air contains chemi-
cals or particles, such as grain, dust, or metal powders; and any other area where
you would normally be advised to turn of your vehicle engine.
BLASTING CAPS AND AREAS
To avoid possible interference with blasting operations; turn your radio OFF near
electrical blasting caps, or in a “blasting area”, or in areas posted: “Turn off the two
way radio.” Obey all signs and instructions.
EXPOSURE TO RADIO FREQUENCY ENERGY
Your two-way radio complies with Australian Communications Authority Radio
Communications (Electromagnetic Radiation-Human Exposure) Standard, 2003.
To assure optimal radio performance and make sure human exposure to radio
frequency electromagnetic energy is within the guidelines set out in the above
standards always adhere to the following radio operating procedures.
RADIO OPERATION AND EME EXPOSURE
Unauthorised antennas, modications, or attachments could damage the radio
and violate compliance. DO NOT hold the antenna when the radio is “IN USE.”
Holding the antenna reduces the effective range. DO NOT use the radio if the
antenna is damaged. If a damaged antenna makes contact with a persons skin,
a minor burn may result.
SAFETY INFORMATION AND WARNINGS

6
ELECTROMAGNETIC INTERFERENCE/COMPATIBILITY
Nearly every electronic device is susceptible to electromagnetic interference (EMI).
To avoid the possibility of electromagnetic interference and/or compatibility conicts,
turn off the radio in any location where posted notices instruct you to do so such as
health care facilities.
SAFETY INFORMATION AND WARNINGS (continued)
AIRCRAFT
When instructed to do so, turn off your radio when on-board an aircraft. Any use of a
radio must be in accordance with applicable regulations per airline crew instructions.
MEDICAL DEVICES – PACEMAKERS
The Advanced Medical Technology Association recommends a minimum separation
of 15cm be maintained between a radio and pacemaker. These recommendations
are consistent with the independent research by, and recommendations of, the U.S.
Food and Drug Administration. People with pacemakers should:
•ALWAYS keep the radio more than 15cm away from the pacemaker when the radio
is powered on.
•NOT carry the radio in the breast pocket (handheld models).
•Use the ear opposite the pacemaker to minimise the potential for interference.
•Turn the radio OFF immediately there is any reason to suspect that interference is
taking place.
MEDICAL DEVICES – HEARING AIDS
Some radios may interfere with some hearing aids. In the event of such
interference, you may want to consult your hearing aid manufacturer to discuss
alternatives.
MEDICAL DEVICES – OTHER
If you use any other personal medical device, consult the manufacturer of your
device to determine if it is adequately shielded from RF energy. You physician may
be able to assist you in obtaining this information.
GENERAL WARNINGS
Some radios may interfere with some hearing aids. In the event of such
interference, you may want to consult your hearing aid manufacturer to discuss
alternatives.

The CB radio is designed for 12/24 Volt DC. 13.8 VDC nominal voltage.
ONLY Replace Fuse with 2 Amp 3AG glass fuse.
ANTENNA INFORMATION
The antenna (not supplied) is of critical importance, to maximize your output
power and receiver sensitivity. A poorly installed, inferior quality antenna or one not
designed for the correct frequency band will give poor performance. You should only
purchase an antenna designed for the 477MHz frequency band.
ANTENNA INSTALLATION
1. Connect the antenna to the rear antenna socket using a PL259 coaxial connector
(not supplied).
2. To obtain maximum performance from the radio, select a high quality antenna and
mount it in a good location.
NOTE: Never press the PTT or CALL button before connecting the antenna to
the radio.

CAUTION
When installing your radio in your vehicle, check that during installation you do not
damage any wiring or vehicle components that may be hidden around the mounting
position. For optimum performance your radio needs to be installed correctly. If
you are unsure about how to install your radio, we suggest you have your radio
professionally installed by a UHF specialist or Auto electrician. When installing the
radio, avoid mounting it close to heaters or air conditioners.
Never press the PTT or CALL button before connecting the antenna to the
radio. Screw the mounting bracket and microphone bracket to rm surfaces.
To install the radio: 1. Fix the radio bracket in a suitable location.
