Electromagnetic Interference/Compatibility
NOTE: Nearly every electronic device is susceptible to electromagnetic
interference (EMI) if inadequately shielded, designed, or otherwise
configured for electromagnetic compatibility.
Avoid Choking Hazard
Small Parts. Not for children under 3 years.
Turn off your radio power in the following conditions:
• Turn off your radio before removing (installing) a battery or
accessory or when charging battery.
• Turn off your radio when you are in a potentially hazardous
environments: Near electrical blasting caps, in a blasting area,
in explosive atmospheres (inflammable gas, dust particles,
metallic powders, grain powders, etc.).
• Turn off your radio while taking on fuel or while parked at
gasoline service stations.
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 (Pacemakers,
Hearing Aids and Other Medical Devices) may be using equipm-
ent that is sensitive to external RF energy.
• 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.
Protect your hearing:
• Use the lowest volume necessary to do your job.
• Turn up the volume only if you are in noisy surroundings.
Guidelines:
• User awareness instructions should accompany the device when
transferred to other users.
• Do not use this device if the operational requirements described herein
are not met.
Operating Instructions:
• Transmit no more than the rated duty factor of 50% of the time. To Tran-
smit (Talk), push the Push to Talk (PTT) button. To receive calls (listen),
release the PTT button. Transmitting 50% of the time, or less, is import-
ant because the radio generates measurable RF energy exposure only
when transmitting in terms of measuring for standards compliance.
• Transmit only when people outside the vehicle are at least the recomme-
nded minimum lateral distance away from a properly installed according
to installation instructions, externally mounted antenna.
• When operating in front of the face, worn on the body, always place the
radio in a Retevis approved clip, holder, holster, case, or body harness
for this product. Using approved body-worn accessories is important
because the use of Non-Retevis approved accessories may result in
exposure levels, which exceed the IEEE/ICNIRP RF exposure limits.
Hand-held Mode
• Hold the radio in a vertical position with the microphone (and
other parts of the radio including the antenna) at least 2.5 cm
(one inch) away from the nose or lips. The antenna should be
kept away from the eyes. Keeping the radio at a proper distance is
important as RF exposure decreases with increasing distance from the
antenna.
Phone Mode
• When placing or receiving a phone call, hold your radio product as you
would a wireless telephone. Speak directly into the microphone.
