IMPORTANT! How to Make Sure You Get the Right Sound Level for Your Needs
5. As you listen to the person on the other end of the line, experiment
by slowly increasing the Volume setting. Also, try moving the
Tone control slightly toward the “Low” or “High” settings.
You need to set this only once. Every time you press the VOL
button, the CrystalTone will use these settings.
NOTE: Some hearing aids may be sensitive when high-frequency
sounds are ampified. If you experience a “crackling” sound, please try
the following:
•Move the Tone control slightly toward “Low” until the
crackling stops.
•Move the Volume control slightly toward “Low” until the
crackling stops.
•Change the Crystal Tone switch to the “B” setting to
reduce high-frequency amplification. Then, repeat the steps
above.(This switch is located on the bottom of your phone.)
