Specifications
For Portable Two-way Communicators:
= When transmitting with a COMMUNICATOR,hold the COMMUNICATOR
in a vertical position with its MICROPHONE 1 to 2 inches (2.5 to 5.0 cm)
away from your mouth. Keep the ANTENNA at least 1 inch (2.5 cm)
from your head and body.
= If you wear a COMMUNICATOR on your body,ensure that the ANTENNA
is at least one inch (2.5 cm) from your body when transmitting.
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.
95-D5901100
! CAUTION
Damaged ANTENNA:
Do not use any COMMUNICATOR that has a damaged ANTENNA.If a
damaged ANTENNA comes in contact with the skin, a minor burn may
result.
Batteries:
All batteries can cause property damage and/or bodily injury such as
burns if conductive material such as jewelry, 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.
! WARNING
ForVehicles with an Air Bag:
Do not place your COMMUNICATOR in the area over an air bag or in the
air bag deployment area. Air bags inflate with great force. If a
COMMUNICATOR is placed in the air bag deployment area and the air
bag inflates, the COMMUNICATOR may be propelled with great force
and cause serious injury to the occupants of vehicle.
Potentially Explosive Atmospheres:
Turn your COMMUNICATOR OFF when in any area with a potentially
explosive atmosphere,unless it is a type specifically qualified for such use
(for example,Factory Mutual Approved).Sparks in such areas could cause
an explosion or fire resulting in bodily injury or even death.
Batteries:
Do not replace or charge batteries in a potentially explosive atmosphere.
Contact sparking may occur while installing or removing batteries and
cause an explosion.
Blasting Caps and Areas:
To avoid possible interference with blasting operations, turn your
COMMUNICATOR OFF near electrical blasting caps or in a "blasting area"
or in areas posted: "Turn off two-way radio".Obey all signs and instructions.
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.
Care and Maintenance
To clean the unit,wipe with a soft cloth dampened with water.Don't use
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,turn it off and remove the batteries immediately.Dry
the BATTERY COMPARTMENT with a solf cloth to minimize 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
