Clarity Power Technology
With the Clarity Power feature, the high fre-
quency 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 C430 has a BOOST CLARITY POWER
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 indi-
cate 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 hand-
set 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
Clarity 430 will provide up to 30 dB of gain.

on the side of the handset. The ringer switch
must be set to ON for the handset to ring.
NOTE: If both handset and base ringer’s are
