WARNING: This Product is designed for users
with hearing disabilities and automatically
amplifies the volume to the highest level
when the Amplify Override switch is set to
“ON”. If you wish to prevent the automatic
amplification, please turn the Amplify
Override switch located on the back of the set
to “OFF”.
Tone Equalizer
The phone’s 3-band tone equalizer boosts the sound of
the three frequency ranges ( 600Hz, 1.2KHz, 2.4KHz ) to
compensate for the ear’s limited sensitivity in these ranges.
1. To turn on the equalizer, press the “amplify” button after
you pick up the handset, or any time during the a call. The
indicator around the button illuminates.
. To adjust the setting open the equalizer cover. Slide each
switch toward “+” to increase or amplify sounds, or toward
“-” to decrease the sound within that specific range.
. To turn off the equalizer press the “amplify” button and the
indicator light turns off.
