Safety and General Information
Important Information on Safe and Efficient Operation
Read This Information Before Using Your Radio
The information provided in this document supersedes the general safety
information contained in user guides published prior to July 2000.
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 transmit (talk), press the Push to Talk (PTT) button.
Page 6 Page 7
• To receive calls, release the 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).
Exposure to Radio Frequency Energy
Your radio is designed to comply with the following national and
international standards and guidelines regarding exposure of human beings
to radio frequency electromagnetic energy:
Two-Way Radio Operation
When using your radio as a traditional two-way radio, hold the radio in
a vertical position with the microphone one to two inches (2.5 to
5 cm) away from the lips.
Facilities
To avoid electromagnetic interference and/or compatibility conflicts, turn
off your radio in any facility where posted notices instruct you to do so.
Hospitals or health care facilities may be using equipment that is sensitive
to external RF energy.
Aircraft
When instructed to do so, turn off your radio when on board an aircraft.
Any use of a radio must be in accordance with applicable regulations per
airline crew instructions.
Potentially Explosive Atmospheres
Turn off your radio prior to entering any area with a potentially explosive
atmosphere. Do not remove, install, or charge batteries in such areas. Sparks
in a potentially explosive atmosphere can cause an explosion or fire
resulting in bodily injury or even death.
Note: The areas with potentially explosive atmospheres referred to above
include fueling areas such as below decks 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. Areas with
potentially explosive atmospheres are often but not always posted.
Blasting Caps and Areas
To avoid possible interference with blasting operations, turn off your radio
when you are near electrical blasting caps, in a blasting area, or in areas
posted: “Turn off two-way radio.” Obey all signs and instructions.
Operational Cautions
Antennas
Do not use any portable radio that has a damaged antenna.
If a damaged antenna comes into contact with your skin, a minor burn can
result.
Safety and General Information
Batteries
All batteries can cause property damage and/or bodily injury such as burns
if a conductive material such as jewelry, keys, or beaded chains touch
exposed terminals.
The conductive 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
Page 8 Page 9
metal objects.
Battery Charger Safety Instructions
1. Do not expose the charger to rain or snow.
2. Do not operate or disassemble the charger if it has received a sharp blow,
or has been dropped or damaged in any way.
3. Never alter the AC cord or plug provided with the unit. If the plug will
not fit the outlet, have the proper outlet installed by a qualified electrician.
An improper condition can result in a risk of electric shock.
4. To reduce the risk of damage to the cord or plug, pull the plug rather than
the cord when disconnecting the charger from the AC receptacle.
5. To reduce the risk of electric shock, unplug the charger from the outlet
before attempting any maintenance or cleaning.
6. Use of an attachment, not recommended, may result in a risk of fire,
electric shock, or personal injury.
7. Make sure the cord is located where it will not be stepped on, tripped
over, or subjected to damage or stress.
8. An extension cord should not be used unless absolutely necessary. Use of
an improper extension cord could result in a risk of fire and/or electric
shock. If an extension cord must be used, make sure that:
• The pins on the plug of the extension cord are the same number, size, and
shape as those on the plug of the charger.
• The extension cord is properly wired and in good electrical condition.
• The cord size is 18 AWG for lengths up to 100 feet, and 16 AWG for
lengths up to 150 feet.
