Customizing your phone

The volume of the handset, speaker, and ringer can be changed using the volume up and down keys on the phone (See number 10 and 11 in the above table). Pressing the volume up or down keychanges the volumes as follows:

yIf the handset is on-hook, the ringer volume is adjusted while the set is ringing for an incoming call.

yIf a paging call is being played, the speaker volume is adjusted.

yIf the handset is off-hook, the handset volume is adjusted.

Call Handling Features

Making and answering calls

Line 1 is the primary line. If an incoming call is received and both lines are idle the call is presented on line

1.If the handset is lifted with both lines idle, line 1 is seized. Only if line 1 has been seized is a second incoming call presented on line 2, or an outgoing call established on line 2. A call made from line 1 or line

2will display the same name and number on the called party’s phone.

On incoming calls, the line LED and Message / Ringing LED will flash.

Make a call

1.Lift the handset.

2.Do one of the following:

yDial the number* or

yPress a programmable key or

yPress (Redial key).

yPress the # key to indicate the end of dialing or wait for the called party to connect.

Answer a call

lift the handset. If a call is received while the handset is offhook, press the ringing line key. If there is an active call on the other line it will automatically be placed on hold.

Place a call on Hold

The Hold key is used to place an active call on hold.

To place a call on Hold:

1. While in an active call press ( Hold key ).

To retrieve a call from Hold:

1.Lift the handset (if on-hook).

2.Press the flashing line key (if off-hook).
