• 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
• Use careful with the earphone maybe possible excessive sound pressure from earphones and
headphones can cause hearing loss
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.
Antennas
•Do not use any portable radio that has a damaged antenna. If a damaged antenna comes into contact
with the skin when the radio is in use, a minor burn can result.
Batteries (If appropriate)
•When 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
•When the transceiver is used for long transmissions, the radiator and chassis will become hot.
Forbid
•Do not use charger outdoors or in moist environments, use only in dry locations/conditions.
•Do not disassemble the charger, that may result in risk of electrical shock or fire.
•Do not operate the charger if it has been broken or damaged in any way.
•Do not place a portable radio in the area over an air bag or in the air bag deployment area. The radio
may be propelled with great force and cause serious injury to occupants of the vehicle when the air
bag inflates.
