This special “self-calibration” feature is only activated when speakerphone mode is
activated. When using the handset or a headset your telephone operates as normal.
Preset Equalizer
To further optimize the sound quality of your speakerphone, it also has an internal audio
equalizer with four available settings. These settings adjust the tone of the speakerphone
to your personal preference. While using your telephone in speakerphone mode, simply
press the Preset EQ button and cycle though these four choices. Pick the one that sounds
the best to you.
1. FLAT - No equalization adjustment is applied to the tone
2. LOW - Emphasizes the deep rich bass tones of the conversation
3. HIGH - Emphasizes the higher and sharper tones of the conversation
4. VOICE CLARITY - Optimizes your speakerphone tone and sound quality
Like the self-calibration described above, the tone equalizer is only activated when
speakerphone mode is activated. If you press the Preset EQ button while using the
handset or a headset, you will hear an error beep, but there will be no difference in the
tone of the conversation.
