BASIC HANDSET OPERATIONS
Volume Control
During a call, the dial on the side controls the level of
volume for the handset and speakerphone. The volume
dial provides up to 16dB of volume before the BOOST
button is activated. Once the BOOST button is pressed,
the C4230 will provide up to 50dB of amplification.
When phone is not in use, the dial on the side controls
the level of the ringer volume.
Boost Override
Select Boost Override on the Main Menu. Use the
Arrow buttons to scroll from ON to OFF. Select
your choice and then press the (soft key) Save.
ON – When the Boost override is set to ON, the
Boost function will be ON every time a call starts.
If the phone hangs up, the Boost will remain ON.
OFF – When the Boost is set to OFF, the Boost
function will be OFF. Every time a call starts, the user
will need to press the BOOST button in order to gain
the extra level of amplification. If the phone hangs up,
the BOOST button will reset to OFF.
Audio Tone
Press the Tone button to change the style of amplifi-
cation. Switching audio tones will change how the
telephone conversation sounds to you. See the matrix
