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 ad here
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 RFenergy exposure only when transmitting (in terms of measuring
standards compliance). Alwayshold the radio approximately 5cm in front of your
mouth with the antenna pointing away from your head.
