Safety Information and Warnings
Information on Safe Operation
Read This Information Before Using Your Radio.
The operation of your radio in Your country is subject to conditions in the following license:
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 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 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 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.
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.
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.
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.
Radio Operation and EME Exposure
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
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.
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.
Not carry the radio in the breast pocket.
Use the ear opposite the pacemaker to minimise 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.
INSTALLATION
Removing the belt clip
Pull the belt clip latch away from the unit.
Installing the Batteries
FOR USE OF RECHARGEABLE BATTERIES:
If your walkie talkie comes with a rechargeable battery pack or USB cable, dual USB adaptor and dual USB car charger.
The fully charging time is about 12 hours.
The adaptor and car charger will only charge the battery pack provided and not other types of rechargeable batteries.
After placing batteries into correct positions, replace the battery cover.
FOR USE OF NON RECHARGEABLE BATTERIES:
1
2
3
.Slide down the battery compartment cover.
.Insert 3 x AAA batteries (not included).
.Position the batteries according to the polarity marking on the battery compartment. After placing batteries into correct positions,
replace the battery cover.
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.
When battery voltage is low, the empty battery symbol will appear and continue to blink. The battery symbol will continuously
blink until it totally drains the battery voltage where then you will have to replace the batteries.
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.

Product Safety and RF Exposure
This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions:
1．This device may not cause harmful interference.
2．This device must accept any interference received, including interference that may cause undesired operation.
FCC Caution:
Caution: To maintain compliance with the FCC’s RF exposure guidelines hold the transmitter and antenna at least 1 inch (2.5
centimeters) from your face and speak in a normal voice, with the antenna pointed up and away from the face, use only the
supplied belt chip for this product and transmitting, use of other accessories may not ensure compliance with FCC RF
exposure guidelines.
This equipment complies with FCC radiation exposure limits set forth for uncontrolled environment. Unauthorized antennas,
modification, or attachments could damage the transmitter and may violate FCC regulations
The device is authorized to operate at a duty factor not to exceed 50%.
Hazardous Environments:
Do not operate the communicator in hazardous environments, explosion or fire may result. Do not operate the communicator
near unshielded electrical blasting caps. Under certain conditions, radios can interfere with blasting operations and may cause
an explosion. Turn your radio to the OFF position to prevent accidental transmission when in a blasting area or in areas
posted: “Turn off two-way radios.” Construction crews often use remote control RF devices to set off explosives.
Never use cleaners or solvents to clean your device. Use a dry, lint-free cloth to clean the battery contacts. Do not submerge
the unit in water.
