Introduction To Digital Clarity Power; Clarity Power Boost - Clarity XL50 User Manual

INTRODUCTION TO DIGITAL CLARITY POWER

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 tolerable.
To enable this type of technology, there is actually a computer
running information inside the phone. Each time the handset is
picked up, the computer will take a little less than a second to
engage. This means that any numbers that are dialed or words that
are spoken before the computer engages, will not be recognized
or heard by the phone.
Clarity Power BOOST Button
The XL50 has a BOOST button that controls the
loudness of the receiver. See Figure A. Once the BOOST
BOOST
button is pressed, an extra level of amplification is added

over the entire range of the Volume Control. During a
call, the BOOST button can toggle the Clarity Power
Figure A function on or off according to the user's needs. The
BOOST button will reset automatically every time the
phone is hung up for at least five seconds. The BOOST
light will illuminate while the BOOST function is
activated. See Page 23.
Warning: Volume may be at a high level. To protect
hearing, lower the Clarity Power Volume Control before
using the phone.

Volume Reset Override
On the bottom of the XL50, there is a Volume Reset
Override switch. When this is set to "On" the
Boost function is automatically enabled every time
the phone is picked up. In standard use, when the
Override is set to "Off" the Boost function will turn
off after the phone is hung up. Setting this switch
to "On" is suggested if all the users of the phone
need the amplification. Setting this switch to "Off"
is useful when people with varying hearing ability use
the phone. See Figure B.
Clarity Power Volume Control
The Clarity Power Volume Control adjusts the level
of volume the handset both in Boost or non-Boost
modes. The volume dial provides up to 15dB of
volume before the BOOST button is activated. Once
the BOOST button is pressed, the XL50 will provide
up to 60dB of gain. See Figure C.
TONE Switch
Adjusting the TONE switch allows you to customize
your hearing experience. Since we all have different
hearing preferences we suggest exploring each
setting to find the one most comfortable for you. The
available settings are: low frequency amplification,
flat amplification, Clarity Power (high frequency)
amplification, and Multi-band Compression (high
frequency) amplification. See Figure D and the
overview of tone settings featured on pages 12-13.
