XLC3.4
Digital Clarity Power
TM
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.
BOOST On / Off
The BOOST button controls the loudness of the
receiver. Once the BOOST button is pressed, an extra
level of amplification is added over the entire range of
volume control.
VOLUME Control Wheel
During a call, the dial on the side controls the level of
volume for handset and speakerphone. The volume dial
provides up to 16dB of volume before the BOOST
button is activated. Once the BOOST button is
pressed, the XLC3.4 will provide up to 50dB of
amplification.
Auto Boost
(For turning Auto Boost On or Off, see page 24.)
ON – When the Auto Boost is set to ON, the Boost
function will be ON every time a call starts. If the
phone hangs up, the Boost function will remain ON.
OFF – When the Auto Boost is set to OFF, the Boost
function will be OFF at the beginning of all calls. Every
time a call starts, the user will need to press the
BOOST button in order to gain the extra level of
amplification.
TONE
