Clarity Power Technology
With the Clarity Power feature, the high
frequency sounds are amplified more than
the low frequency sounds so words are
not just louder, but clearer and easier
to understand.
Clarity Power On/Off Button
The Clarity 435 has a CLARITY POWER
button that controls the loudness of the
receiver. Once the CLARITY POWER button
is pressed, an extra level of amplification is
added over the entire range of the Volume
Control. The default state of this button is
determined by the BOOST ON/OFF switch
(top end of base of unit, see below). During a
call, the CLARITY POWER button can toggle
the Clarity Power function on or off according
to the user’s needs.
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 volume control adjusts the level of volume
the handset and headset receive. The volume
dial provides up to 15 dB of volume amplifi-
cation before the Clarity Power button is acti-
vated. Once the Clarity Power button is
pressed, the Clarity 435 will provide up to
30dB of amplication.
Boost On/Off Switch
This switch will enable/disable the reset
feature of the Clarity Power button
as follows:
ON- When the BOOST ON/OFF switch is
set to “ON”, the Boost function (Clarity
Power) will be ON every time a call starts,
and will default to ON every time the phone
hangs up for more than 5 seconds. During
a call, the Clarity Power button can toggle
the Clarity Power ON or OFF according to
the user’s needs.
OFF- When the BOOST ON/OFF switch is set
to “OFF”, the Boost function (Clarity Power)
will be OFF every time a call starts, and the
user needs to press the Clarity Power button
in order to gain the extra level of amplifica-
tion. If the phone hangs up for at least 5
seconds, the Clarity Power will reset to OFF.
During a call, the Clarity Power button can
toggle the Clarity Power function ON or OFF
according to the user’s needs.
