Guarantee
not exceed the specified gain by the manufacturer declared.
• To avoid interference, turn off the radio in areas where signs are posted to do so.
• DO NOT operate the transmitter in areas that are sensitive to electromagnetic
radiation such as hospitals, aircraft, and blasting sites.
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 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.

RF ENERGY EXPOSURE AND PRODUCT SAFETY GUIDE
Local Government Regulations
When radios are used as a consequence of employment, the Local Government
Regulations requires users to be fully aware of and able to control their exposure to
meet occupational requirements. Exposure awareness can be facilitated by the use of
a product label directing users to specific user awareness information. Your Retekess
radio has a RF Exposure Product Label. Also, your Retekess user manual, or separate
safety booklet includes information and operating instructions required to control your
RF exposure and to satisfy compliance requirements.
Unauthorized modification and adjustment
Changes or modifications not expressly approved by the party responsible for compli-
ance may void the user’s authority granted by the local government radio management
departments to operate this radio and should not be made. To comply with the corres-

Replacement of any transmitter component (crystal, semiconductor, etc.) not authorized
by the local government radio management departments equipment authorization for
this radio could violate the rules.
FCC Requirements:
• This device complies with part 15 of the FCC Rules. Operation is subject to the
following two conditions:
(1) This device may not cause harmful interference, and
(2) this device must accept any interference received, including interference that
may cause undesired operation.
