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.
