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 could 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 connecting the headset or earpiece
  • Limit the amount of time you use headsets or earpieces at high volume
  • When using the radio without a headset or an earpiece, do not place the radio’s speaker directly against your ear
