Information on Safe Operation
Read This Information Before Using Your CRYSTAL Radio. The operation of your UHF radio in
Australia is subject to conditions in the following license:
In Australia the ACMA Radio communications (Citizen Band Radio Stations) and in New Zealand by
MED the General User Radio License 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.
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.

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.

All batteries can cause property damage and/or bodily injury such as burns if conductive material
such as jewellery, 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 b
attery, 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.
Potentially Explosive Atmospheres
Turn your radio OFF when in any area with a potentially explosive atmosphere. Sparks in such areas

Exposure to Radio Frequency Energy
Your CRYSTAL 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

antenna is damaged. If a damaged antenna makes contact with your skin, a minor burn can result. If you wear a radio on
least 5cm from your body when transmitting.
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.
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.
People with pacemakers should:
 ALWAYS keep the radio more than 15cm from their pacemaker when the radio is turned ON.

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.

Transmitting Range
The talk range will depend on your surroundings and environment it will be affected by 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.
Channel 5 and 35 (paired for Duplex repeaters) are reserved as emergency channels and should be used only in an
emergency. CTCSS and DCS will not operate on channels 5 and 35.
A list of currently authorised channels can be obtained from the ACMA website in Australia and the MED website in
New Zealand. Channel 11 is a calling channel generally used to call others and channel 40 is the customary road vehicle
channel.
Once contact is established on the calling channel, both stations should move to another unused “SIMPLEX” channel
to allow others to use the calling channel.
Channels 22 and 23 are for Telemetry and Telecommand use, voice communications are not allowed on these channels
by law. Channel 9 and above are the best choices for general use in Simplex mode.

BATTERY INFORMATION
Charging the Battery Pack
The battery pack is not charged at the factory; please charge it before use. Charging the battery pack
for the first time after purchase or extended storage (more than 2 months) may not bring the battery
pack to its normal operating capacity. After fully charging/ discharging cycle for two or three times, the
operating capacity will reach its best performance. The battery pack life is over when its operating time
decreases even though it is fully and correctly charged. Change to a new battery pack.
Charger Applied
Please use the specific charger appointed by our company. Other models may cause explosion and
personal injury. After installing the battery pack, if the radio displays low battery with red flashing
lamp or voice prompt, please charge the battery.
NOTES
▲
Do not short the battery terminals or throw the battery into fire. Never attempt to remove the

BATTERY INFORMATION
casing from the battery pack. We bear no responsibility on any results caused by modifying the
battery.
▲
The ambient temperature should be between 5℃ and 40℃ while charging is in progress. Charging
outside this range may not fully charge the battery.
▲
Always switch OFF the transceiver equipped with a battery pack before charging. Otherwise, it will
interfere with correct charging.
▲
To avoid interference with charging, please do not cut off the power or take out the battery during
charging.
▲
Do not recharge the battery pack if it is already fully charged. This may shorten the life of the battery
pack or damage the battery pack.
▲
Do not charge the battery or transceiver if it is damp. Dry it before charging to avoid danger.
When keys, ornamental chain or other electric metals contact with the battery terminal, the battery
may cause damage or injury. If the battery terminal short circuits it will generate a lot of heat,
please be careful when you carry or use the battery, please put battery or radio into insulated
container. Do not put it into metal container.
WARNING:

BATTERY INFORMATION
You can charge the battery or transceiver separately.
1. Plug the AC adaptor into the AC outlet, and then plug the cable of the AC adaptor into the DC jack
located on the back of the Charger.

charging time depends on the dump battery. After fully charged, please remember
to remove the battery or transceiver out of charger. Over charging will shorten the
battery life and reduce its performance.

Emergent Charging
Connect the transceiver directly with adaptor or car charger to charge.
Note:Please power off the transceiver before charging the transceiver in this way. Also, it takes
longer time (totally 12hours) to fully charge the transceiver in this way.
How to Store the Battery
1. If the battery needs to be stored, keep it in status of 50% discharged.
2. It should be kept in low temperature and dry environment.
3. Keep it away from hot places and direct sunlight.
WARNING:
▲
Do not short circuit battery terminals.
▲
Never attempt to remove the casing from the battery pack.
▲
Never assemble the battery in dangerous surroundings, spark may cause explosion.
▲
Do not put the battery in hot environment or throw it into fire, it may cause explosion.
