FEATURES
Digital Clarity Power™Technology
With Digital Clarity Power, high frequency sounds are amplified
more than 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.
Tone Selection
Another added benefit of our patented Digital Clarity Power
is the ability to customize the phones performance to your
specific hearing needs.The XL50 has four available tone settings
that each provide different solutions to help you better hear
phone conversations.
Smart-PlexingTechnology
Smart-Plexing is the new and advanced way that the XL50 deals
with possible feedback issues and is unique to Clarity phones.
Feedback occurs when the sound coming out of the earpiece is
detected by the microphone on the handset and is reprocessed
by the telephone.This causes the telephone to squeal or howl.
Most phones will temporarily shut off the microphone to fix this
problem, but that results in only one person being able to talk
at a time.The Clarity Professional XL50 uses a “smart plexing”
system where it enables full functionality on both ends of the
conversation at all times. Only Clarity offers such a solution
that will allow full conversation while controlling feedback.
Notification Accessories
A Wireless Lamp Flasher and Bed Shaker can be connected
to the phone to allow for a variety of ways to alert the user
that the phone is ringing.The Wireless Lamp Flasher will cause
any connected light source to flash when the phone rings.The
Bed Shaker is an accessory that will begin to vibrate when the
phone rings.

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
button is pressed, an extra level of amplification is added
over the entire range of theVolume Control. During a
call, the BOOST button can toggle the Clarity Power
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 5 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.

Override
Volume Reset Override
On the bottom of the XL50, there is aVolume 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 PowerVolume Control
The Clarity PowerVolume 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 amplifica-
tion, flat amplification, Clarity Power (high frequency)
amplification, and Multi-band Compression (high
frequency) amplification. See Figure D and the over-
view of tone settings featured on pages 12-13.

OVERVIEW OF XL50 TONE SETTINGS
The XL50 offers four different tone settings to provide an experience that
may be customized to fit a specific users need. The illustration above shows
how the four settings relate to each other and the amount of amplification
they give to the different frequencies of sound.
The following charts illustrate each tone setting separately. Read each
explanation and examine the charts to help decide what setting will be most
beneficial. In addition, make sure to listen to each setting while making a deci-
sion. The best way to choose between the settings is to listen to them all and
decide which one provides the best telephone conversation experience.

The first tone setting is one that emphasizes the low frequency sounds. This
is for those who have a hard time hearing lower pitched sounds.

The second tone is a flat amplification of all sounds. This is for the user who
wants full volume amplification for every type of sound. This is suggested if
the user is wearing a digital hearing aid while using the phone.
The third tone setting is our set Clarity Power that begins to focus more
on the higher frequency sounds and add speech intelligibility. It is a medium
between tone setting two (2) and four (4).

OVERVIEW OF XL50 TONE SETTINGS
The fourth tone setting provides full emphasis on speech intelligibility using
Clarity’s Multi-Band Compression. Clarity MBC also enables the phone to
amplify the soft sounds to an audible level while controlling the louder sounds,
keeping them bearable. This is for the user who may be able to hear the words
being spoken, but does not understand or cannot distinguish what is being said.

GETTING STARTED
There are five initial steps involved in setting up
your XL50
1. Insert four AA alkaline batteries for back-up in case of
AC power outage. See below.
2. Decide if you want the phone to sit on a desk or hang
on the wall.
3. Connect the telephone components. Pages 15-16.
4. Program up to eleven (11) telephone numbers to call
with the press of a memory button. See Page 18.
5. Set up Notification Options. See Page 20.
Installing the Backup Batteries
If there is a power outage, the XL50 will operate for up
to 48 hours with four AA alkaline backup batteries (not
included). If the phone is not in use, the batteries will stay
charge for several months. See Figure 1.
To install new batteries:
1. Slide open the battery compartment cover on the
bottom of the telephone. To open the battery
compartment, use a pen or similar fine point instru-
ment to press into small opening below the compart
ment door. This opening is pointed out with the #2
in Figure 1.
2. Install four fresh batteries. Be sure to observe battery
polarity as imprinted on the base of the compartment.
The battery indicator on the top panel will light up if
the batteries are running low.
The phone operates as a regular phone if there is no
power or battery. Certain functions of the phone do
require power however. If no power is being supplied to
the phone, it will have no indicator lights, the loud ringer
will be disabled, there will be no amplification, and the
lighted keypad will not be lit.
