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.
• Limit the amount of time you use headsets at a high volume.
•  When using the radio without a headset, do not place the radio’s speaker directly against your ear.
• If you experience hearing discomfort, ringing in your ears, or speeches that are muffled, you should stop listening to your radio through your headset, and have your hearing checked by your doctor.
