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 fuelling 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.
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 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.
