6. SAFETY INSTRUCTIONS
6.1 Damaged antenna
Do not use any receiver that has a damaged antenna. If a damaged
antenna comes in contact with the skin, a minor burn may result.
6.2 Batteries
As batteries can cause property damage and/or bodily injury such as
burns if conducting material such as jewellery, keys or beaded chains
touches exposed terminals. The conductor may complete an electric
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.
6.3 For vehicles with air-bag
Do not place your receiver in the area over an air-bag or in the air-bag
expansion area. Air-bags inflate with great force. If a receiver is placed
in the bag expansion area and the air bag inflates, the receiver may be
propelled with great force and cause serious injury to vehicle occupants.
6.4 Potentially combustible atmospheres
Switch your receiver off when in any area with a potentially combustible
atmosphere, unless it is a type specifically designed for such use. Sparks
in such areas could cause an explosion or fire resulting in bodily injury or
even death.
6.4.1. Batteries
Do not replace or charge batteries in a potentially combustible
atmosphere. Contact sparking may occur while installing or removing
batteries and cause an explosion.
6.4.2. Blasting caps and areas
To avoid possible interference with blasting operations, turn your
receiver off near electrical blasting caps, in a ‘blasting area’ or in areas
marked: ‘Turn off two-way radios’. Obey all signs and instructions.
Note: Areas with potentially combustible 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 switch off your vehicle engine.
7. CARE AND MAINTENANCE
To clean the unit, wipe with a soft cloth moistened with water. Don’t
use a cleaner or solvents on the unit; they can harm the case and leak
inside, causing permanent damage. Battery contacts may be wiped with
a dry lint-free cloth.
If the unit gets wet, switch it off and remove the batteries immediately.
Dry the battery compartment with a soft cloth to minimise potential
water damage. Leave the cover off the battery compartment overnight
or until completely dry. Do not use the unit until completely dry.
To ensure optimal unit performance, the following operating procedures
should be observed:
7.1 For Portable Two-way Communicators
When transmitting with a communicator, hold the communicator in a
vertical position with its microphone 2.5 to 5.0 cm away from your
mouth. Keep the antenna at least 2.5 cm from your head and body.
If you wear a communicator on your body, ensure that the antenna is at
least one 2.5 cm from your body when transmitting.
7.2 Electromagnetic Interference/Compatibility
Nearly every electronic device is susceptible to electromagnetic
interference (EMI) if inadequately shielded, designed or otherwise
configured for electromagnetic compatibility.
Turn your unit OFF in any facilities where posted notices instruct you to
do so. Hospitals or health care facilities may be using equipment that is
sensitive to external RF energy.
Turn your unit OFF when on board an aircraft when instructed to do so.
Any use of the unit must be accordance with airline regulations or crew
instructions.
