Using Personal FM Systems with the PSP
What is an FM System?
An FM (Frequency Modulated) system is a wireless communication technology
commonly used in the classroom to overcome the adverse effects of distance and
competing noise.
Connecting the Child’s PSP to an FM System:
1. Ensure that you have obtained the appropriate FM Adapter Cable to use with
the FM System. If you are not sure please contact the FM manufacturer.
2. Ensure that the FM System is functioning appropriately by listening to the FM
System through an amplied speaker or Walkman-style earphones.
3. Keeping the FM System and Sound Processor in the “off” position, connect the
Sound Processor and FM receiver through the Auxiliary Input Jack via the
adapter cable.
4. Set any gain, output, or tone controls on the FM receiver per the child’s
audiologist or FM manufacturer’s recommendations (as applicable).
5. Ensure that the volume on the FM receiver and the Volume and Sensitivity
Controls on the PSP are both set to the minimum level.
6. Turn on the transmitter, receiver, and Sound Processor in that order.
NOTE: It is important that you turn on the equipment in the proper order to
prevent the child from hearing any adverse sound percepts.
7. Gradually increase the Volume and Sensitivity on the student’s Sound Processor
to their everyday settings or as specied by the child’s audiologist.
8. Gradually increase the volume on the FM receiver to a comfortable listening
level or as specied by child’s audiologist or the FM manufacturer.
9. Complete a functional listening check:
• Administer a listening task that you know the user can perform at 100%,
such as the Ling Six Sound Test and/or common phrases.
• Perform these listening tasks in an auditory-only condition and in close
proximity to the child. Repeat the task at a distance of several meters, noting
that no changes in performance are observed with the FM in quiet.
• The functional listening check can also be repeated in noise to assess the
effects of the cochlear implant + FM.
Tips to Reduce Interference:
1. Ensure that the FM Adapter Cable does not wind around the Headpiece Cable.
2. Ensure that the transmission range is not exceeded. The broadcast range
between FM transmitters and receivers may begin to break up at distances
greater than 40 feet indoors and 120 feet outdoors.
3. Observe areas in the classroom, or other environments, that can cause “dead
spots” in transmission. Complete a listening check with the FM System in the
classroom to listen for any problem areas and avoid seating the child in these
problem areas.
