Safety Information and Warnings
Information on Safe Operation
WARNING
Read This Information Before Using Your Oricom Radio.
Radio Antenna
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 tted with Air Bags
Do not place your radio in the area over an air bag or in
the air bag deployment area. Air bags inate with great
force. If a radio is placed in the air bag deployment area
and the air bag inates, 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.

WARNING
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 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 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 t wo- way r adio contains a t ran smitter and
a receiver. To cont ro l your exposure and ens ur e
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
WARNING
Unauthorized antennas, modifications, 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 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
Ne arly every electron ic d evice is suscepti ble to
el ec tromagnetic interference (EMI). To avo id the
possibility of electromagnetic interference and/or
compatibility conicts, 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.

WARNING
Safety Information and Warnings
Medical Devices - Pacemakers
The Adv ance d Med ical Tech nology A sso ciat ion
recommends that a minimum separation of 6 inches
(15cm) be maintained between a handheld wireless
radio and a pac emaker. These recommendations
are consistent with the inde pendent research by
and recommendations of the U.S. Food and Drug
Administration.
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
Never use your radio outdoors during a thunderstorm.
Keep the radio out of reach of babies and young
children.

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.

Repeater Station
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)
http://www.oricom.com.au/support/repeater or visit
http://www.tropinet.com/uhf-repeaters/
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 conrm your setting.
e. The RPT icon will display to indicate that Duplex is set on that
channel.
