FOREWORD
RF Energy Exposure and Product Safety
Guide for Portable Two-Way Radios
ATTENTION!
Before using this product, read the RF Energy
Exposure and Product Safety Guide that ships with
the radio which contains instructions for safe usage
and RF energy awareness and control for
compliance with applicable standards and
regulation.
ACOUSTIC SAFETY
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 can be affected. Hearing
damage from loud noises is sometimes
undetectable at first and can have a
cumulative effect.
To protect your hearing:
• Use the lowest volume necessary to do
your job.
• Increase the volume only if you are in noisy
surroundings.
• Reduce the volume before connecting
headset or earpiece.
• Limit the amount of time you use headsets
or earpieces at high volume.
• When using the radio without a headset or
