SAFETY INFORMATION AND WARNINGS
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
chemicals 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 (continued)
ELECTROMAGNETIC INTERFERENCE/COMPATIBILITY
Nearly every electronic device is susceptible to electromagnetic interference (EMI). To avoid the pos-
sibility 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.
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
Keep the radio out of reach of babies and/or young children. Never use your radio outdoors
during a thunderstorm.
BATTERIES
All batteries can cause property damage and/or bodily injury such as burns if conductive material
such as jewelery, keys, or beaded chains touch exposed terminals. The material may complete
an electrical circuit (short circuit) and become quite hot. Exercise care in handling any charged
battery, particularly when placing it inside a pocket, purse, or other container with metal objects.
Do not replace or charge batteries in a potentially explosive atmosphere. Contact sparking may
occur while installing or removing batteries and cause an explosion.

FUNCTION- CTCSS & DCS
WHAT IS CTCSS AND DCS?
CTCSS (Continuous Tone-Coded Squelch System) and DCS (Digitally Coded Squelch) modify
the transmission signal to allow multiple users to share the same channel without disturbing each
other. This is an important feature on a radio when there are many radio users in the same area.
CTCSS continuously superimposes any one of about 50 low-pitch audio tones on the transmitted
signal, ranging from 67 to 254 Hz.
DCS was designed as the digital replacement for CTCSS. DCS adds a 134.4 bps (sub-audible)
bit stream to the transmitted audio
CTCSS or DCS is enabled by on the radio through selectable sub channels. When CTCSS or
DCS is enabled, incoming signals must be on the same CTCSS or DCS sub channel as the receiving
radio or they will be ltered out.
NOTE: The CTCSS and DCS Tone Charts can be found on page 10 of this instruction manual.
FUNCTION- Dual Channel Monitor (DCM)
WHAT IS DUAL CHANNEL MONITOR (DCM)?
Generally on a UHF only one channel can be monitored at a time (unless the radio is in scan mode).
Dual channel monitor allows two channels to be monitored simultaneously.
FUNCTION- Button Beep
WHAT IS BUTTON BEEP?
When buttons are pressed on the radio (exc. PTT Button), the radio emits a beep tone to indicate
the button has been pressed. The radio has button beep default on.

FUNCTION- Using The UHF Radio
TRANSMIT AND RECEIVE PROCEDURE
Your UHF radio contains a transmitter and receiver. To control your exposure and ensure
compliance with the general population/uncontrolled environment exposure limits, always adhere
to the following procedure:
• Transmit no more than 50% of the time.
• To receive calls, release the “(PTT) BUTTON” on the microphone handpiece.
• To transmit (talk), press the “(PTT) BUTTON” on the microphone handpiece.
When powered on and not transmitting, the radio is always in receive mode. When a signal is
received the LCD will display the signal strength, and then you can hear if the other party is calling.
NOTE: You may not receive the call if you set a high “squelch off” level of the transceiver.
If current channel has been programmed with signaling, you can only hear the call from the same
signaling, other calls can not be heard. For others to receive your transmission, they must be on the
same channel as you and if CTCSS or DCS is enabled, the same sub channel must also be selected.
Be sure that the channel you want to use is not in busy state through monitoring for a while by
pressing the programmed Squelch off “(PF1) BUTTON”. Under these conditions, press the “(PTT)
BUTTON” and speak into microphone. Please keep around 2.5-5cm distance between microphone
and your lip. And please speak in normal tone to make the receiver obtain best tone quality.
NOTE: Holding [PTT], signal strength shows on the screen when the transceiver is transmitting.
Release the PTT to receive.
NOTE: Transmitting 50% of the time, or less, is important because the radio generates
measurable RF energy exposure only when transmitting (in terms of measuring standards
compliance).
NOTE: Do not transmit between two radios that are less than 1.5m apart, otherwise you may
experience interference.
NOTE: The UHF radio is simplex “one way at a time”. While you are speaking, you can not
receive a transmission.
NOTE: The UHF radio is an open licence band. Always identify yourself when transmitting.
TRANSMITTING RANGE
The transmitting range will depend on the antenna, terrain, surroundings and environment, it will
be affected by obstructions such as hills, buildings and foliage. The use of duplex mode will
extend the transmission range in areas where a repeater station is present.
