mounting on wall)✔ Desktop/wall adapter

CAUTION! Do not plug the CrystalToneinto any telephone line other than a standard,analog telephone line. Connection to a digitalsystem may damage the CrystalTone or thetelephone system and will void your warranty.

1. SELECTING A LOCATIONThe CrystalTone requires a standard (analog)telephone line with either pulse or tone (alsocalled t o u c h t o n e) dialing. To use theC r y s t a l To n e with a digital system, somemodifications to the telephone line arerequired.

Set up the CrystalTone in a place where:✔ There is a phone jack nearby.✔ The surface it is set on, or mounted to, is

stable and secure.✔ The area is protected from excessive heat or

humidity.

2. REMOVE DESKTOP/WALL ADAPTERIf it is connected, remove the desk-top/walladapter. (This will bereplaced after setupis complete.)

3. SETTING PULSE OR TONE DIALINGThe CrystalTone is preset touse t o n e dialing becausethis is used by mosttelephone lines. If your lineuses pulse dialing, move theswitch located on the bottom of theCrystalTone to the “Pulse” setting.

4. SETTING UP THE CRYSTALTONE

For Desktop Use

1. Connect the uncoiled end of the handsetcord to the jack on bottom of theCrystalTone . Plug the other end of the cordinto the handset.

2. If the desktop/wall adapter is not removed,remove it now (see step 2).

3. Plug the telephone line cord into thetelephone line jack on the bottom of theC r y s t a l To n e and the other end into thewall phone jack.

4. Replace the desktop/wall adapter so thatthe larger side is along the top edge of theCrystalTone .

5. Set the C r y s t a l -Tone on a sturdysurface such as adesk, table orcounter.

CARE & REPAIR ■ 9

CARE & REPAIRCLEANINGNever use liquid or aerosol cleaners. Unplugthe CrystalTone and wipe with a damp cloth.If necessary, use a small amount of mild soapsuch as dishwashing soap on the cloth.

PROBLEM SOLVINGMy CrystalTone does not ring whenI get a call.

Check the Ringer on/off switch on the rightside of the CrystalTone .

Be sure that the ringer switch on the bottom ofthe CrystalTone is not set to Off. If you havetoo many phones and/or computer modemshooked up in your home, you may haveexceeded the “ringer equivalence” of yourtelephone service. Contact your telephoneservice provider to verify that your service isadequate for your needs.

All of my Speed-Dial numbers havebeen erased.

There was probably an extended interruptionin the telephone line. The S p e e d - D i a lnumbers are saved using power theCrystalTone receives from the telephone line.If you disconnect the CrystalTone from thewall jack or if the telephone companyexperiences an outage, the Speed-Dialnumbers may be erased after about 45minutes.

The volume coming through thehandset is not loud enough.

Make sure the Outgoing Volume is off. Thebutton and light are on the top of the

C r y s t a l To n e (see “Adjusting OutgoingVolume ” on page 7).

You may also notice a decrease in v o l u m ewhen another phone on an extension of thesame line is also off hook.

I experience feedback or a “squeal”when hanging up the handset orsetting it down on a table.

Press the button to turn offamplification before setting down the handsetor hanging up.
