Clarity® Power™ Technology
With Clarity Power, the high frequency sounds are amplified more than the low
frequency sounds so words are not just louder, but clearer and easier
to understand.
BOOST – Clarity Power On/Off
The C4105 has a button that controls the loudness
of the receiver. Once the BOOST button is pressed,
an extra level of amplification is added over the en-
tire range of the volume control.
The TALK button will light ORANGE to indicate the
CLARITY POWER feature is activated.
WARNING: When the TALK button is lit ORANGE volume may be at a high
level. To protect hearing, lower the volume control to minimum before using.
Volume Control
The dial controls the level of volume the handset and headset receive. The
volume dial provides up to 15 decibels of volume before the CLARITY POWER
button is activated. Once the CLARITY POWER button is pressed, the C4105
will provide up to 40 decibels of amplification.
Tone Switch
Adjusting the TONE switch allows you to customize your hearing experience.
Since we all have different hearing preferences we suggest exploring each set-
ting to find the one most comfortable for you.
Handset Ringer
Set the switch marked Ringer OFF/VIBE/ON located on the side of the hand-
set. When VIBE is selected the handset will ring and vibrate when receiving an
incoming call. The ringer switch must be set to ON or VIBE for the handset
to ring.
NOTE: If both handset and base ringers are set to OFF, the visual ringer will
flash to indicate there is an incoming call.
Boost On: Talk
button is ORANGE
Boost Off: Talk
button is GREEN

visual ringer will also stay lit while the phone is in use.
BOOST ON/OFF Switch
This switch will disable the reset feature of the BOOST Clarity Power button
as follows:
ON – When the BOOST ON/OFF switch is set to ON, the Boost function will
be ON every time a call starts, and will default to ON every time the phone
hangs up. During a call, the BOOST Clarity Power button can toggle the Clarity
Power ON or OFF according to the user’s needs.

This device complies with Part 15 of the FCC Rules. Operation is subject to the
following two conditions: (1) This device may not cause harmful interference,
and (2) this device must accept any interference received, including interference
that may cause undesired operation.
Your equipment has been tested and found to comply with the limits of a Class
B digital device, pursuant to Part 15 of FCC rules. These limits are designed to
provide reasonable protection against harmful interference in
residential installation.
This equipment generates, uses and can radiate radio frequency energy and, if
not installed and used in accordance with the instructions, may cause harm-
ful interference to radio communications. However, there is no guarantee
that interference will not occur in a particular installation; if this equipment
does cause harmful interference to radio or television reception, which can be
determined by turning the equipment off and on, you are encouraged to try to
correct the interference by one of the following measures:

24 25
1. Where it can be done safely, reorient the receiving television or
radio antenna.
2. To the extent possible, relocate the television, radio or other receiver
with respect to the telephone equipment. (This increases the separation
between the telephone equipment and the receiver.)
3. Connect the telephone equipment into an outlet on a circuit different from
that to which the television, radio, or other receiver is connected.
4. Consult the dealer or an experienced Radio/TV Technician for help.
CAUTION: Changes or modifications not expressly approved by the manu-
facturer responsible for compliance could void the user’s authority to operate
the equipment.
