RF Energy Exposure and Product Safety
Guide for Portable Two-way Radios
Attention!
Before using this accessory, read this guide
which contains important operating instructions
for safe usage and RF energy awareness and
control for compliance with applicable standards
and regulations.
The Remote Speaker Microphone (RSM), when
attached to the radio, is restricted to occupational
use only to satisfy FCC/ICNIRP RF energy
exposure requirements. Before using this
product, read the RF energy awareness
information and operating instructions in the
Product Safety and RF Exposure booklet
enclosed with your radio to ensure compliance
with RF energy exposure limits.
Acoustic Safety
Exposure to loud noises from any source for
extended periods of time may temporarily or
permanently affect your hearing. The louder the
volume of the radio, the less time is required
before your hearing can be affected.
Hearing damage from loud noise is sometimes
undetectable at first and can have a cumulative
effect.
To 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 attaching
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 speaker of the radio
directly against your ear.
• If you experience hearing discomfort, ringing in
your ears, or muffled speech, you should stop
listening to your radio through your headset or
earpiece, and have your hearing checked by
your doctor. To change the volume level, refer
to Radio Product Safety Leaflet or CPS for
Surveillance extra loud (xL) Kit Configurations.
