WARNING
SAFETY INFORMATION
Your wireless hand-held portable transceiver contains a low power transmitter.
This product sends out radio frequency (RF) signals when the Push-to-Talk (PTT)
button is pressed. The device is authorized to operate at a duty factor not to
exceed 50%. In August 1996, the Federal Communications Commissions (FCC)
To control your exposure and ensure compliance with the general population or
uncontrolled environment exposure limits,

Implantable Cardioverter-Defibrillators (ICDs) or other active implantable
medical devices (AIMD) should:
from their pacemaker when the
radio is turned on.
Consult with their physicians regarding the potential risk of interference
from radio frequency
transmitters, such as portable radios (poorly
shielded medical devices may be more susceptible to interference).
Turn the radio OFF immediately if they have any reason to suspect that
interference is taking place.
Do not carry the radio in a chest pocket or near
the implantation site,
and carry or use the radio
on the opposite side of their body from the
implantable device to minimize
the potential for interference.

WARNING
WARNING
- Hearing Aids
Some digital wireless radios may interfere with some hearing aids. In the
event of such interference, you may want to consult your hearing aid
manufacturer to discuss alternatives.
- Other Medical Devices
If you use any other personal medical device,
consult the manufacturer of
your device to determine if it is adequately shielded from RF energy.
Your
physician may be able to assist you in obtaining this information.
Protect your hearing:
Use the lowest volume necessary to do your job.
Turn up the volume only if you are in noisy surroundings.
Turn down the volume before adding headset or earpiece.
Limit the amount of time you use headsets or earpieces at high volume.
When using the radio without a headset or earpiece, do not place the
radio's speaker
directly against your ear.
Note:
Exposure to loud noises from any source for extended periods of time
may temporarily or permanently affect your hearing. The louder the radio's
volume, the less time is required before your hearing could be affected.
Hearing damage from loud noise is sometimes undetectable at first and
can have a cumulative effect.
Avoid Burns
Antennas
o not use any portable radio that has a damaged antenna. If a damag-
ed antenna comes into contact with the skin when the radio is in use, a
minor burn can result.
Batteries (If appropriate)
en the conductive material such as jewelry, keys or chains touch
exposed terminals of the batteries, may complete an electrical circuit
(short circuit the battery) and become hot to cause bodily injury such as
burns. Exercise care in handling any battery, particularly when placing it
inside a pocket, purse or other container with metal objects.
Long transmission
en the transceiver is used for long transmissions, the radiator and
chassis will become hot.
WARNING
Safety Operation
