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 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 earpiece, do not place the radio’s speaker directly against your ear.
