adjusted to the desired level by momentarily pressing the push button.
N
OTE
: Pressing the volume push button increases the volume in 3 dB increments. The volume starts
at 0 dB and increases to a maximum of 18 dB. Pressing the push button a seventh time returns the
volume to 0 dB.
3. Dial the desired number.
4. After completion of the call, place the handset on-hook.
Volume Control Jumper Setting
The handset receiver volume control is factory-set to default to its original setting (0 dB) when the
telephone is hung up. To save the volume control setting, jumper J4, which is factory-set at positions 2
and 3, must be moved to positions 1 and 2, after the desired volume is reached.
