Direct Audio Input Hearing Aids:
If your hearing aid has a direct audio input boot, you can obtain a cord from your hearing aid
manufacturer to plug directly into the PFM receiver.
Applications:
The Personal FM is designed to provide hearing assistance when background noise or distance from
the sound source make listening difficult. The microphone and transmitter are placed close to the
desired sound source to help minimize background noise and to effectively eliminate the distance
between the listener and the sound source.
Low-Amplification Fittings:
Classroom applications:
The PFM System can be used with headphones or earphones for Central Auditory Processing
Disorders, Learning Disabilities, or Attention Deficit Disorders. The PFM System is used primarily to boost
speech sounds above other background noises, making it easier for the listener to focus on what is
being said. The optional Rugged Headphone (HED 012 - children's size and HED 014 - adult's size) are
recommended for this application. The EAR 013 Single Mini Earphone or EAR 014 Dual Mini Earphone
can also be used.
Mild to Moderate Hearing Loss:
Classroom applications, TV listening, riding in a car, one-on-one conversations:
The PFM System can be used with the Single or Dual Mini Earphone (EAR 013 or EAR 014) for
moderate amplification fittings. The Button Receiver Earphone (EAR 012 WC) is also available for use
with a snap-on custom earmold.
The PFM System is also suitable for temporary mild hearing loss due to otitis media. The Rugged
Headphones or Surround Earphone (EAR 022) are recommended since they do not enter the ear
canal.
Severe to Profound Hearing Loss:
Classroom applications, TV listening, riding in a car, one-on-one conversations:
For severe to profound hearing loss, the PERSONAL FM System should be used in conjunction with a
hearing aid. A Neckloop can be used with hearing aids that have a telecoil. An adaptor cord can
be used with hearings that have direct audio input.
In Case of Difficulty:
If the system does not appear to be functioning:
1. Make sure the batteries are fully charged in the Transmitter and Receiver.
2. Make sure the Microphone is plugged into the transmitter and the earphone is plugged into the
receiver.
3. Contact your dealer for further help.
If you experience interference:
Interference can be signals from another radio service, excess hiss or buzzing noise, or a "blocking" of
the signal. If this occurs, your PFM System can be changed to a new operating channel by your
dealer.
