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.
