Safety Information and Warnings  
Information on Safe Operation  
Read This Information Before Using Your Oricom Radio.  
Radio Antenna  
WARNING  
Do not use any radio that has a damaged antenna. If  
a damaged antenna comes in contact with the skin, a  
minor burn may result.  
Unauthorized antennas, modifications, or attachments  
could damage the radio and violate compliance. Do NOT  
change or modify the antenna.  
Do NOT hold the antenna when the radio is “IN USE.”  
Holding the antenna reduces range and may cause  
bodily harm.  
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 Air Bags  
Do not place your radio in the area over an air bag or in  
the air bag deployment area. Air bags inflate with great  
force. If a radio is placed in the air bag deployment area  
and the air bag inflates, the radio may be propelled with  
great force and cause serious injury to the occupants of  
the vehicle.  
Batteries  
All batteries can cause property damage and/or bodily  
injury such as burns if conductive material such as  
jewelry, keys, or beaded chains touches 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.

Safety Information and Warnings  
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 fire resulting in injury or even death.  
WARNING  
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 off 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 Oricom 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 procedures.  
Transmit and Receive Procedure  
Your two-way radio contains a transmitter and  
a 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.  
• To transmit (talk), press the Push to Talk (PTT) button.  
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).  
Always hold the radio approximately 5cm in front of your  
mouth with the antenna pointing away from your head.

Safety Information and Warnings  
Radio Operation and EME Exposure  
Unauthorized antennas, modifications, or attachments  
could damage the radio and violate compliance.  
WARNING  
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 your skin, a  
minor burn can result.  
If you wear a radio on your body when transmitting,  
always fit the radio on the belt clip (supplied). Always  
ensure the radio and it's antenna are at least 5cm from  
your body when transmitting.  
Electromagnetic Interference/Compatibility  
Nearly every electronic device is susceptible to  
electromagnetic interference (EMI). To avoid the  
possibility of electromagnetic interference and/or  
compatibility conflicts, turn off your 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  
onboard an aircraft. Any use of a radio must be in  
accordance with applicable regulations per airline crew  
instructions.

Safety Information and Warnings  
Medical Devices - Pacemakers  
The Advanced Medical Technology Association  
recommends that a minimum separation of 6 inches  
(15cm) be maintained between a handheld wireless  
radio and a pacemaker. These recommendations  
are consistent with the independent research by  
and recommendations of the U.S. Food and Drug  
Administration.  
WARNING  
People with pacemakers should:  
• ALWAYS keep the radio more than 15cm from their  
pacemaker when the radio is turned ON.  
• Not carry the radio in the breast pocket.  
• Use the ear opposite the pacemaker to minimize the  
potential for interference.  
• Turn the radio OFF immediately if 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.  
Other Medical Devices  
If you use any other personal medical device, consult  
the manufacturer of your device to determine if it is  
adequately shielded from RF energy. Your physician may  
be able to assist you in obtaining this information.  
General warnings

Getting Started  
Low Battery Meter Indicator  
The radio can detect the low battery level when the battery  
voltage goes low. The battery icon will display the low  
battery status as follows;  
When battery voltage is low the empty battery symbol will  
appear and continue to blink.  
The battery icon will continue to blink until it totally drains  
the battery voltage.  
Power Saving Mode  
Your radio has special circuitry designed to extend the life  
of your battery. When the unit is not used for 4 seconds,  
it will automatically switch low power mode. The Power  
Saving feature does not affect the Radio's ability to receive  
transmissions. When a signal is detected, it automatically  
returns to full power mode.  
Transmitting range  
The talk range depends on the environment and terrain. The  
radio can reach (up to about 3km) in wide open spaces, without  
obstructions such as hills or buildings. Don’t try to use two radio  
units which are less than 1.5m (5 feet) apart. Otherwise, you may  
experience interference.  
Talk range depends on the terrain. It will be affected by concrete  
structures, heavy foliage and by operating radios indoors or in  
vehicles.

Operation  
Duplex operation via Repeaters  
This feature allows to use local repeater stations that are designed  
to automatically re-transmit your broadcast over a large area thus  
giving you increased range.  
Repeaters stations are privately operated radio systems installed  
throughout Australia.  
You can see a list of repeater sites by following this link to our  
website (note this list is always being updated)  
For example, if you wish to access a repeater station in your area  
which operates on channel 2 you only need to set the Duplex  
access on this Channel.  
So, if you are in the range of a local repeater which transmits on  
channel 2, after setting your radio to allow access of the repeater  
on that channel, you will select channel 2 as normal, but during  
transmit operation your radio will automatically transmit to the  
repeater on channel 32.  
Turning on/off Duplex on channels  
a. Select the required channel to suit the repeater station you  
wish to access (Channels 1 – 8 only)  
b. Press the Menu button twice, “RPT” icon will display  
c. Press the UP or DOWN button to set the Duplex function to On  
or Off.  
d. Press the PTT button to confirm your setting.  
e. The RPT icon will display to indicate that Duplex is set on that  
channel.
