Digital Clarity Power™ Technology
With Digital 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. It also provides intelligent
amplification to make soft sounds audible, while
keeping loud sounds bearable.
BOOST – Clarity Power On/Off
The C4210 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
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
dB of volume before the CLARITY POWER button
is activated. Once the CLARITY POWER button
is pressed, the C4210 will provide up to 40 dB of
amplification.
Tone Switch
The C4210 has three (3) TONE settings. Adjusting
the TONE switch changes the style of amplification
and allows you to customize your hearing experi-
ence. We all have different hearing preferences. We
suggest exploring each setting to find the one you
find most comfortable.
