TELEPHONE HANDSET

Digital Clarity Power Technology
With Digital Clarity Power, the high frequency 

sounds are amplified more than the low fre-

quency sounds so words are not just louder, but 

clearer and easier to understand. It also provides 

intelligent amplification to make soft sounds  

audible, while keeping loud sounds bearable. 

BOOST – Clarity Power On/Off 
The C4205 has a button that controls the loud-

ness of the receiver. Once the BOOST button is 

pressed, an extra level of amplification is added 

over the entire 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 C4205 will pro-

vide up to 40 decibels of amplification.

Tone Switch
Adjusting the TONE switch allows you to custom-

ize your hearing experience. Since we all have 

different hearing preferences we suggest explor-

ing each setting to find the one most comfortable 

for you.
