On the back of the XLC2 base,
there is an AUTO BOOST
ON / OFF switch, to enable the
Auto Boost Function.

WARNING: VOLUME MAY BE LOUD!

When this is set to “ON,” the Boost function is
automatically enabled every time the phone is picked up -
the call starts in Boost ON mode.
When the Auto Boost Override switch is set to “OFF”
(default setting), the Boost function turns off after the
phone is hung up - the call starts in Boost OFF mode.
Setting this switch to “ON” is recommended if all of the
users of the telephone need the additional amplication.
Setting this switch to “OFF” is useful when people with
varying hearing abilities use the phone.
During a call, pressing the BOOST button toggles the Boost
function ON or OFF according to the user’s needs.
