exposure levels, which exceed the IEEE/ICNIRP RF exposure limits.
Transmit no more than the rated duty factor of 50% of the time. To Transmit (Talk), push the Push to Talk (PTT)
button. To receive calls (listen), release the PTT button. Transmitting necessary information or less, is important
because the radio generates measurable RF energy exposure only when transmitting in terms of measuring for
standards compliance.
•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 authorized 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 interference with other devices or
systems. To avoid such 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.
•Portable Device, this transmitter may operate with the antenna(s) documented in this filing in Push-to-Talk and
body-worn configurations. RF exposure compliance is limited to the specific belt-clip and accessory configura-
tions as documented in this filing and the separation distance between head and the device or its antenna shall
be at least 2.5 cm.
Hand-held Mode(if applicable)
• 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.
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.).
WARNING
•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 equipment 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.
• Turn down the volume before adding headset or earpiece.
• Limit the amount of time you use headsets or earpieces at high volume.
WARNING
• 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
