Avoid Choking Hazard
Small Parts. Not for children under 3 years.
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
• Use careful with the earphone maybe possible excessive sound pr-
essure 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.
Avoid Burns
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.
Safety Operation
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.
To reduce risk
• Pull by the plug rather than the cord when disconnecting the charger.
• Unplug the charger from the AC outlet before attempting any maintenance
or cleaning.
• Contact Retekess for assistance regarding repairs and service.
• The adapter shall be installed near the equipment and shall be easily
accessible
• Risk of explosion if battery is replaced by an incorrect type. Dispose of
used batteries according to the instructions.
• Adapter shall be installed near the equipment and shall be easily accessible.
• The plug considered as disconnect device of adapter.
• The operating temperature of the EUT can’t exceed the specified range.

RF Exposure Information
• DO NOT operate the radio without a proper antenna attached, as this may damage the
radio and may also cause you to exceed RF exposure limits. A proper antenna is the
antenna supplied with this radio by the manufacturer or an antenna specifically author-
ized by the manufacturer for use with this radio, and the antenna gain shall not exceed
the specified gain by the manufacturer declared.
• DO NOT transmit for more than 50% of total radio use time, more than 50% of the time
can cause RF exposure compliance requirements to be exceeded.
• During transmissions, your radio generates RF energy that can possibly cause interfe-
rence with other devices or systems. To avoid such interference, turn off the radio in
areas where signs are posted to do so.
• The device complies with RF specifications when the device used at 5mm from your
body. Third-party belt-clips, holsters, and similar accessories used by this device should
not contain any metallic components. Body-worn accessories that do not meet these
requirements may not comply with RF exposure requirements and should be avoided.

Warnings
This radio uses electromagnetic energy in the radio frequency (RF) spectrum to provide
communications between two or more users over a distance. RF energy, which when
used improperly, can cause biological damage.
All Retekess radios are designed, manufactured, and tested to ensure they meet
government-established RF exposure levels. In addition, manufacturers also recommend
specific operating instructions to users of the radios. These instructions are important
because they inform users about RF energy exposure and provide simple procedures
on how to control it.
Please refer to the following websites for more information on what RF energy exposure
is and how to control your exposure to assure compliance with established RF exposure
limits: http://www.who.int/en/
Local Government Regulations
