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 RSM 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 inflate with great force, if a radio is placed in the airbag deployment area and the airbag inflates, 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 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.
EXPOSURE TO RADIO FREQUENCY ENERGY
- Your two-way radio complies with the Australian Communications Authority Radio Communications (Electromagnetic Radiation-Human Exposure) Standard, 2003.
- To assure optimal radio performance and make sure human exposure to radiofrequency 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, 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 a person’s skin, a minor burn may result.
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 the radio in any location where posted notices instruct you to do so such as healthcare facilities.
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. Your physician may be able to assist you in obtaining this information.
