Keypad
The numeric keypad with the keys 0 to 9, *, and # is used to enter digits and letters.
Depending on the operating mode, different actions can be performed (see the table
below):
Entry of digits only (e.g., when dialing a phone number)
Typing in letters and digits by pressing the keys repeatedly (similar to a cellular phone),
etc.
Dialing
There are two methods to begin a call from the idle state of the phone. You can either dial
with the handset resting in the cradle and then pick it up or press speaker and then dial the
number. The phone shows the current communication status in the display.
Accepting a call
Picking up the handset or pressing speaker will accept the call. The phone is now in a
call. Pressing MUTE/DEL while the phone is ringing will send the call to your
voicemail.
Terminating a call
End calls by placing the handset on its cradle or pressing speaker. The phone will
terminate the call and return to the idle state.
Adjusting the volume
In the idle state or while making a call, you can use the arrow keys to increase or lower
the volume. The audio device (speaker, handset, headset) that you are currently using can
be adjusted.
Mute / Un-mute
To mute the microphone during a call, press the Mute key, Un-mute to enable the
microphone again.
Handset / Hands-free / Headset
The phone supports calls made using the handset or hands-free capability. During a call,
it is possible to switch between both modes by pressing the Speaker key.
When a headset is connected, the phone will treat the headset as the output device for
calls. The speaker key is therefore used to accept and terminate calls.
Park & Retrieve
To Park a call is to put it on hold in a place anyone could retrieve. While in a call press
the ## key an dial 70#. Wait for the system to tell you which extension the call is parked
on (71, 72).
To retrieve a parked call, dial the number where the call is parked. (71-79) Press the send
button and you will be connected to the parked call.
Hold and Resume
When a call is in progress, pressing hold button puts the call on hold, i.e., neither party
can hear the other.
Pressing the line key will resume the call. While a call is on hold, you can establish
another call by dialing the desired number.
