Important Safety Instructions
Read and understand the Installation Guide & User Manual. When using your telephone
equipment, basic safety precautions should always be followed to reduce the risk of fire,
electric shock and injury to person, including the following.
WARNING: The CSC50 Phone is capable of amplifying sounds to a loud volume. It is
important to instruct all potential users of its proper operation. It is advised to adjust the
volume control to the minimum level (Low) when not in use and alert other users that
hearing damage can potentially result from misuse.
WARNING: To avoid the possibility of electrical shock, do not use this product near water
(For example, near a bathtub, wash basin, kitchen sink or laundry tub, in a wet basement
or near a swimming pool) while in the bathtub or shower or when you are wet. If the phone
becomes submerged in water, do not attempt to retrieve it until after you have unplugged
the line cord from the modular wall jack. Do not plug the phone back in until it has dried
completely.
WARNING: Avoid using the telephone during electrical storms. There may be a remote
risk of electric shock from lightning. If the electrical storm is present in your immediate
area, possibility of electrical shock exists.
WARNING: Do not use the phone if you suspect a gas leak in the area. The phone’s
electrical contacts could create a spark, which could ignite any heavy concentration of
leaking gas.
WARNING: Do not use liquid cleaners or aerosol cleaners on the telephone. Use a damp
cloth for cleaning.
WARNING: No telephone should ever be placed near an open radiator or heating regis-
ter.
WARNING: Occasionally a power surge can occur on electrical lines without warning. With
any electrical device that you plug into an outlet, it is suggested you use a surge protector.
A surge protector will prevent power surges from damaging your telephone. Surge protec-
tors are simple devices available at your local hardware store.

when you select the Strobe Ringer.
If you purchased the optional Bed Shaker, simply plug it into the shaker jack (See figure
#11) and place it between your mattress and box spring. Caution: For safety and correct
functionality considerations, your CSC50 Phone can only be guaranteed when used with
our ClearSounds™ Bed Shaker, model CS-SHK.

PHONE MOUNTING INSTALLATIONS
The telephone may be placed on a shelf or table, or may be fixed to a wall using the
mounting bracket.
Plug the AC Adapter into the AC power back on the back of your phone, then into an
electrical outlet or surge protector, if you are using one. NOTE: The adapter is required
for the telephone to work correctly. If the adapter is accidentally unplugged (or in case
of power failure) and if the batteries are dead or not installed, minimal restricted phone
features only will work on the phone (make a call or answer incoming call).
IMPORTANT: Please remove the clear plastic Caller ID tab. This film tab is only for display
and to protect your Caller ID display during shipping.
Desk / Table Use
1. Connect one end of the 6ft telephone cord to the line jack on the back of your
CSC50 Phone and connect the other end to a modular phone jack (RJ11C).
2. Connect the handset coil cord (curly cord) to the handset and to the telephone
(See figure #17).
3. Lift the handset and listen for a dial tone. If you hear a dial tone, your phone is ready
to use. If there is no dial tone, check all your cords to make sure they are plugged in
securely.
Wall Mount Use
1. Slide the handset hanger tab out and reverse its position (rotate it 180 degrees).
Slide it back into place so that the hook points up (See figure #18). This will keep the
handset from falling out of the cradle when it is mounted on the wall.
2. Plug the 8in short phone cord into the telephone jack on the CSC50, run phone cord
underneath wall plate adapter and through the opening.
3. Insert the Wall Plate adapter. Hold the wall plate adapter so that the raised mounting
pins line up with the phone’s keyholes on the CSC50. Once the holes are lined up,
push the wall plate adapter in towards the CSC50 and then slide the plate upwards
until it is securely seated on the phone. (See figure #19)
4. With the Wall Plate adapter installed, plug the 8in short phone cord into the jack on
the wall.
5. Holding the phone slightly above the mounting screws on the wall jack, push the
phone against the mounting screws so they are hooked into upper and lower key-

hole slots on the back of the phone. Slowly slide the phone down until it snaps into
place (See figure #20).
6. Connect the handset coil cord (curly cord) to the handset and to the telephone.

Voice Amplification and Tone
Your CSC50 Phone is equipped with a specialized amplification function designed to fit
your needs. You can adjust the volume and tone (sound frequency range) of the incoming

button (See figure #24). This turns the incoming voice amplifier ON. When the ampli-
fier is ON, you will see the red light on the left side of the “AMPLI” button light up.
i.e. “AMPLI”
Figure #23 – Audio / Headset Jack Button

2. Adjust the volume and tone to fit your needs by adjusting the VOLUME (See figure
#25) and TONE (See figure #26) controls until you find the right levels for you. The
Volume Control increases sound volume. Slide the Volume Control to the right
to increase the volume and slide it to the left to decrease the volume. The Tone
Control allows you to fit your specific hearing needs. Slide the Tone Control to the
left to boost the lower frequency range. Slide the Tone Control to right to boost the
high frequency range. This allows individuals with BOTH high frequency and low
frequency hearing loss to use the CSC50 Phone.
3. For additional, situational amplification, press and hold the HANDSET BOOST but-
ton located just below the earpiece on the inside of the handset (See figure #26). By
pressing and holding this additional handset boost button, you get an extra 10 dB
gain of amplification.
IMPORTANT NOTE: The Handset Boost button is designed to be used when listening
only. When you are ready to speak, release the button. Press it again when the extra
amplification is necessary. Failure to release the button when speaking will result in the
other party not hearing you. Use this additional handset boost button (See figure #27) for
the following reasons:
a. The caller has a very soft speech
b. There is a lot of background noise
c. You are in a noisy environment
d. The connection on the phone line is weak
CAUTION: This telephone can produce very high (loud) sound levels. Repeated incre-
mental exposure to amplification levels greater than 18 dB may be harmful to people
without hearing loss. Always adjust the volume control to the minimum setting after using
