• Turn the radio OFF immediately if they have any reason 

  to suspect that interference is taking place.

• Do not carry the radio in a chest pocket or near the 

  implantation site, and carry or use the radio on the 

  opposite side of their body from the implantable device

  to minimize the potential for interference.

- Hearing Aids

Some digital wireless radios may interfere with some 

hearing aids. In the event of such interference, you may 

want to consult your hearing aid manufacturer to discuss 

alternatives.

- Other Medical Devices

If you use any other personal medical device, consult the 

manufacturer of your device to determine if it is adequately 

shielded from RF energy. Your physician may be able to

assist you in obtaining this information.

Protect your hearing:

• Use th

e lowest volume necessary to do your job.

• Turn up the volume only if you are in noisy surroundings.

• Turn down the volume before adding 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.

Note: 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.
