Operation

1. Lift the handset to place a call.

2. The handset receiver volume control, which is located on the stainless steel front panel, can be

adjusted to the desired level by momentarily pressing the push button.

: Pressing the volume push button increases the volume in 3 dB increments. The volume starts

OTE

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.
