CONGRATULATIONS!
The CrystalTone works just like a standard telephone. It also has some very helpful features. Please take a few minutes to familiarize yourself with its capabilities.
SPEED-DIAL EMERGENCY BUTTONS
The CrystalTone has three special buttons that you can program with emergency numbers. When you need to dial an emergency number quickly, such as the police, just lift the receiver and press the button labeled with the picture of a police badge ( ). The emergency buttons are NOT preprogrammed. You will need to program them before use (see “Saving Emergency Numbers” on page 8).
SPEED-DIAL DIRECTORY BUTTONS
Save up to 10 frequently called numbers for easy dialing. Once the number is saved, simply lift the receiver and press the desired Speed­Dial button to place a call.
REDIAL BUTTON
When you get a busysignal, you can call back later with the press of a button. The button automatically calls the last number that was dialed.
FLASH BUTTON
Some telephone service features like C a l l Waitingrequire a “hook flash” which is a very brief interruption of the connection like hanging up the phone for one second. The timing for a hook flash can be tricky but the
button times it perfectly so you don’t have to worry about accidentally disconnecting your call.
AUDIO JACK
You can connect some assistive listening devices and headsets directly into the CrystalTone audio jack (3.5 mm).
HOLD BUTTON
You can place a call on hold by pressing the
button. Neither you nor the person on the other end of the line will hear sounds from the line. To resume your conversation, press the button a second time.
VOLUME (VOL)
Everyone in your house can use the CrystalTone. When you need more volume, just press the button. The CrystalTone remembers any volume and tone adjustments made previously. The amplification turns off when the receiver is hung up or when is pressed again.
LOUD RING WITH RING INDICATOR
The ringer has a separate volume control so you can select the ring volume and pitch that work best for you. Plus, the Ring Indicator lights up whenever the phone rings to provide a visual alert.
OUTGOING VOLUME
You can amplify the sound of your voice being heard by the person on the other end of the line with the button (Outgoing Volume).
MUTE BUTTON
You can silence your outgoing voice by pressing the button. The person on the other end of the line will not be able to hear sounds from where you are.

OVERVIEW
OV E RVIEW ■3
To set up the C r y s t a l To n e , all you do is connect the telephone line! You can also choose to mount the phone on the wall.
CrystalTone includes the following parts:
CrystalTone amplified phoneHandset with coiled cord7-foot telephone line cord6-inch telephone line cord (for use when
mounting on wall)
Desktop/wall adapter
CAUTION! Do not plug the CrystalTone into any telephone line other than a standard, analog telephone line. Connection to a digital system may damage the CrystalTone or the telephone system and will void your warranty.
1. SELECTING A LOCATION
The CrystalTone requires a standard (analog) telephone line with either pulse or tone (also called t o u c h t o n e) dialing. To use the C r y s t a l To n e with a digital system, some modifications to the telephone line are required.
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 ADAPTER
If it is connected, remove the desk-top/wall adapter. (This will be replaced after setup is complete.)
3. SETTING PULSE OR TONE DIALING
The CrystalTone is preset to use t o n e dialing because this is used by most telephone lines. If your line uses pulse dialing, move the switch located on the bottom of the CrystalTone to the “Pulse” setting.
4. SETTING UP THE CRYSTALTONE
For Desktop Use
1. Connect the uncoiled end of the handset cord to the jack on bottom of the CrystalTone. Plug the other end of the cord into the handset.
2. If the desktop/wall adapter is not removed, remove it now (see step 2).
3. Plug the telephone line cord into the telephone line jack on the bottom of the C r y s t a l To n e and the other end into the wall phone jack.
4. Replace the desktop/wall adapter so that the larger side is along the top edge of the CrystalTone.
5. Set the C r y s t a l - Tone on a sturdy surface such as a desk, table or counter.
INSTALLATION

I N S TA L L AT I O N
Mounting on a Wall
1. Flip the handset hook over so that the hook points up and will hold the handset when you hang it up.
2. Connect the uncoiled end of the handset cord to the jack on bottom of the CrystalTone. Plug the other end of the cord into the handset.
3. Plug the 6-inch telephone line cord into the CrystalTone.
4. Replace the desktop/wall adapter so the larger side is down. This aligns the CrystalTone so that it is flat when mounted on the wall.
5. Plug the telephone cord into the wall jack. Then, line up the holes in the wall­mount bracket with the mount­ing studs on the wall plate. Hook the bracket on the studs then pull down.
5. CONNECTING AN EXTERNAL SIGNALER
To use a separate, optional signal light, plug the signaler into an unused extension telephone wall jack. If you have only one jack that is being used by the C r y s t a l To n e , you can use a “Y- J a c k ” (also called a “duplex jack”). Plug both the CrystalTone and the signaler into the Y-jack and plug the Y-jack into the wall jack. You can purchase a Y-jack at any store that sells telephones.
6. CONNECTING A HEADSET RECEIVER
The CrystalTone provides an audio jack for direct audio connections with some assistive listening technology. A headset with a 3.5 mm jack may also be used. The headset may be either mono or stereo. The jack, which is labeled with the headset symbol ( ), is located on the right side of the CrystalTone.
I N S TA L L ATION ■5
CALLING & ANSWERING
The C r y s t a l To n e works just like any telephone.
PLACING A CALL
1. Lift the Handset.
2. Listen for the dial tone.
3. Dial the number of the person you are calling. When the person answers the phone, begin your conversation.
4. During a conversation, you may want to adjust the volume and quality of the sound coming through the handset (see “Adjusting the Sound ” on the next page).
ANSWERING A CALL
1. When you receive a call, the CrystalTone rings and the Ring Indicator flashes slowly along with the rings.
NOTE: If the ring volume is not loud enough to alert you to a call, you can increase the ring volume (see “Adjusting the Sound” on the next page).
2. Pick up the handset to answer the call and begin your conversation.

SOUND A D J U S T M E N T S
ADJUSTING THE SOUND
CONVERSATION VOLUME
To increase the overall volume of the person’s voice coming through the handset:
1. Press the button. The red light comes on.
2. Slide the control, located on the top of the CrystalTone, toward the right side of the phone until the volume is a comfortable level for you.
VOLUME
To return the volume to your preferred setting, press the button at any time during a conversation. The red light comes on, and the CrystalTone recalls the settings for:
Conversation VolumeConversation Tone
The amplification turns off when you hang up the handset.
CONVERSATION TONE
The CrystalTone has two controls that work together to adjust the tone of the sounds coming through the handset. You may wish to experiment to see which works best for you.
1. Set the Crystal To n e switch, located on the bottom, to setting “A.” This enhances sound for people with high­frequency hearing loss.
2. Press the button. The red light comes on.
3. Move the s l i d e c o n t r o l to experience the sound changes
while the other person is talking. If you slide it up, toward the top of the phone, more high-pitched sounds will come through the handset.
4. Set the Crystal Tone switch to setting “B.” People who experience low-frequency hearing loss may prefer this setting.
5. You can experiment with different combinations of Crystal Tone setting A or B and Tone setting from low to high to get the most effective setting.
6. When you have found the setting that works best for you, leave the Crystal Tone switch in place.
Each time you press the button, the C r y s t a l To n e will return to your previous settings. You may wish to adjust the slide control from time to time depending on who you are speaking with.
RING VOLUME
You can set the Ring Volume to Off, Low, Medium or High with the switch on the bottom of the CrystalTone.
RINGER ON/OFF
You can turn the ringer off using the switch on the right side of the CrystalTone. This will also turn off the Ring Indicator, so it will not light up when you get a call.
RING PITCH
You can change the ringer pitch with the switch on the bottom of the C r y s t a l To n e . Choose from low, medium or high pitch.

USING FLASH
Some telephone service features like Call Waiting or 3-Way Calling require a “h o o k flash” which is a very brief interruption of the connection like hanging up the phone for one second.
When using hookflash during a conversation, press the button. There is a brief click or silence on the line. If using Call Waiting, the second call should now be connected.
ADJUSTING OUTGOING VOLUME
If the person you are talking to tells you that they cannot hear you very well, you can increase the volume of your outgoing voice by pressing the button.
When this feature is on, you can still increase the volume of what you hear up to 15 db.
USING HOLD
You can place a call on hold by pressing the
button.
To use the Hold feature during a conversation, press the button. Confirm that the red light above the button is lit. As long as this light is on, the person on the other end of the line cannot hear what you are saying. When you are ready to resume your conversation, press the button a second time. You can also resume your conversation from another telephone on the same line. This is done by hanging up the handset while the CrystalTone is on hold, then picking up the handset of the second phone. The CrystalTone is automatically hung up.
USING MUTE
You can mute your outgoing voice by pressing the button.
To use the Mute feature during a conversation, press the button. Confirm that the red light above the button is lit. As long as this light is on, the person on the other end of the line cannot hear what you are saying. When you are ready to resume your conversation, press the button a second time.

S AVING PHONE NUMBERS
SAVING PHONE NUMBERS
NOTE: The Speed-Dial numbers are saved using power that the C r y s t a l To n e r e c e i v e s from the telephone line. If you disconnect the C r y s t a l To n e from the wall jack, or if the telephone company experiences an outage for an extended period of time , the Speed-Dial numbers may be erased.
SAVING EMERGENCY NUMBERS
The CrystalTone has three buttons reserved for emergency numbers:
Police Hospital Fire
You choose what number is stored for each button. These buttons are NOT preprogrammed with emergency numbers.
NOTE: The Speed-Dial buttons with these symbols are provided only as a convenience. Ultratec assumes no responsibility for customer reliance upon this memory feature.
Follow the steps under “Saving Speed-Dial Numbers ” to set emergency numbers, except that in Step 4, press the Emergency button instead of the Speed-Dial Directory button.
SAVING SPEED-DIAL NUMBERS
1. Lift the handset.
2. Press the button.
3. Dial the phone number that you wish to save just as if you were calling that number.
4. Press the Speed-Dial Directory button that you wish to use for this number.
5. Hang up the handset.
6. Remove the clear plastic Directory cover: Use the point of a pencil or other small object to lift from the notches located on each side of the cover.
7. In black ink, write the first name of the person on the Directory label. There is a space next to each Speed-Dial button. Print large, clear letters so you will be able to see easily which person you are calling.
8. Repeat these steps for each number that you save. Replace the clear plastic Directory cover when you are finished.

CARE & REPAIR ■9
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 S p e e d - D i a l numbers are saved using power the CrystalTone receives from the telephone line. If you disconnect the CrystalTone from the wall jack or if the telephone company experiences an outage, the Speed-Dial numbers may be erased after about 45 minutes.
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
C r y s t a l To n e (see “Adjusting Outgoing Volume” on page 7).
You may also notice a decrease in v o l u m e 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 button to turn off amplification before setting down the handset or hanging up.

AVIS D'INDUSTRIE CANADA
AVIS: L'étiquette d'Industrie Canada identifie le matériel homologué. Cette étiquette certifie que le matériel est conforme aux normes de protection, d'exploitation et de sécurité des réseaux de télécommunications, comme le prescrivent les documents concernant les exigences techniques relatives au matériel terminal. Le Ministère n'assure toutefois pas que le matériel fonctionnera à la satisfaction de l'utilisateur.
Avant d'installer ce matériel, l'utilisateur doit s'assurer qu'il est permis de le raccorder aux installations de l'entreprise locale de télécommunication. Le matériel doit également être installé en suivant une méthode acceptée de raccordement. L'abonné ne doit pas oublier qu'il est possible que la comformité aux conditions énoncées ci­dessus n'empêche pas la dégradation du service dans certaines situations.
Les réparations de matériel homologué doivent être coordonnées par un représentant désigné par le f o u r n i s s e u r. L'entreprise de télécommunications peut demander á l'utitisateur de débrancher un appareil à la suite de réparations ou de modifications effectuées par l'utilisateur ou à cause de mauvais fonctionnement.
Pour sa propre protection, l'utilisateur doit s'assurer que tous les fils de mise à la terre de la source d'énergie électrique, des lignes téléphoniques et des canalisations d'eau métalliques, s'il y en a, sont raccordés ensemble. Cette précaution est particulièrement importante dans les régions rurales.
AVERTISSEMENT: L'utilisateur ne doit pas tenter de faire ces raccordements lui-même; il doit avoir recours à un service d'inspection des installations électriques, ou à un électricien, selon le cas.
AVIS: L'indice d'équivalence de la sonnerie (IES) assigné à chaque dispositif terminal indique le nombre maximal de terminaux qui peuvent être raccordés à une interface. La terminaison d'une interface téléphonique peut consister en une combinaison de quelques dispositifs, à la seule condition que la somme d'indices d'équivalence de la sonnerie de tous les dispositifs n'excède pas 5.

GENERAL SAFETY
When using your C r y s t a l To n e , basic safety precautions should always be followed to reduce the risk of fire, electric shock, and injury to persons.
1. Read and understand all instructions.
2. Follow all warnings and instructions on the CrystalTone.
3. Unplug the C r y s t a l To n e from the t e l e p h o n e jack before cleaning. Do not use liquid or aer­osol cleaners. Use a damp cloth for cleaning.
4. Do not use the C r y s t a l To n e near water, for example, near a bath tub, wash bowl, kitchen sink, laundry tub, in a wet basement or near a swimming pool.
5. Do not place the CrystalTone on an unstable cart, stand or table. The CrystalTone may fall, causing serious damage to the CrystalTone.
6. To reduce the risk of electric shock, do not disassemble the CrystalTone, but take it to a qualified service person when service or repair work is required. Opening or removing covers may expose you to dangerous voltages or other risks. Incorrect re-assembly can cause electric shock when the C r y s t a l To n e is subsequently used.
