Outgoing Speech Amplification (OSA)
This function amplifies your speech so it becomes louder to the person on the other
end of the call . To enable this function, press and hold the BOOST button for five sec-
onds . The phone beeps; the function can be enabled/disabled while on a phone call or
in standby mode . The OSA light (part of the visual ringer)turns on when this function is
enabled .
To return to the default setting for your voice volume level, press and hold the BOOST
button again for five seconds . You will hear a beep confirming that the function is dis-
abled .
NOTE: In order to experience the best audio quality for both parties during a call, we
recommend you turn on this function only if your voice is too quiet. OSA is not active
in speakerphone mode.
