XLC3.4
Digital Clarity Power
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.
