dard modular plug to a 3.5 mm connector. If you have the new style rear panel,

Testing Location
It is very important to pick a testing location that is free of magnetic disturbanc-
es, especially those caused by fluorescent lights and power lines. To do this:
1. Locate a wide range linear hearing aid with good low frequency response
and a telecoil switch.
2. Set the hearing aid to operate in the telecoil position and turn the gain con-
trol up to its full-on position.
