CARE & REPAIR
CLEANING
Never use liquid or aerosol cleaners. Unplug the CrystalTone and wipe with a damp cloth. If necessary, use a small amount of mild soap such as dishwashing soap on the cloth.
PROBLEM SOLVING
My CrystalTone does not ring when I get a call.
Check the Ringer on/off switch on the right side of the CrystalTone .
Be sure that the ringer switch on the bottom of the CrystalTone is not set to Off. If you have too many phones and/or computer modems hooked up in your home, you may have exceeded the “ringer equivalence” of your telephone service. Contact your telephone service provider to verify that your service is adequate for your needs.
All of my Speed-Dial numbers have been erased.
There was probably an extended interruption in the telephone line. The
The volume coming through the handset is not loud enough.
Make sure the Outgoing Volume is off. The 
button and light are on the top of the CrystalTone (see “Adjusting Outgoing
Volume ” on page 7).
You may also notice a decrease in volume when another phone on an extension of the same line is also off hook.
I experience feedback or a “squeal” when hanging up the handset or setting it down on a table.
Press the VOL button to turn off amplification before setting down the handset or hanging up.
