Boost Override - Clarity Alto Guia Del Usuario

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 ampli-
fied;
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 Alto has a Custom mode, which
can be accessed by pressing and holding the TONE button until the numeric keypad
flashes once and you hear a beep; the display shows a blinking number (indicating
the tone setting); roll the VOLUME wheel up and down (range: 0-60 settings) un-
til you have reached the best setting for your hearing . To save this setting, release
the volume wheel and wait until the display shows the volume level again, OR press
TONE quickly – you will see "tc" briefly displayed on your screen . 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.
