Boost Override - Clarity Alto PLUS User Manual

The available settings are:
t1 - Low frequency emphasis: best used to hear low pitched sounds;
t2 - Flat frequency response: best if you need all audible range of voice to be amplified;
t3-t4 - High frequency emphasis: two settings, to best fit most people's levels of hearing
loss .
ha (Hearing Aid) - this setting is recommended for Hearing Aid users – to ensure
best audio performance while accounting for the presence of the hearing aid near the
handset
Custom (tc) - in addition to the preset settings, the AltoPlus has a Custom mode,
which can be accessed by pressing and holding the TONE button until the phone beeps
and numeric keypad flashes once; the display shows "T: 00" (a 2-digit number); roll the
VOLUME wheel up and down (range: 0-60 settings) until you have reached the best
setting for your hearing . To save this setting, release the volume wheel and wait until the
display shows the call timer and volume level again, OR press TONE quickly – you will
see "Custom" displayed on your screen briefly . You now have a sixth tone setting –
customized to your needs . You can toggle through all presets and the new custom setting
by pressing the TONE button during your calls .
NOTES:
1. The Custom tone mode is available only after it is enabled (by pressing and
holding the TONE button during a call).
2. Boost button is not active in speakerphone mode.

ter 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 .
