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
