USING A WIRELESS HEADSET (IQ750EHS)
To answer or start a call, press the Headset's Call Control key (this is
typically the button on the headset's earpiece: see Headset User
- (Fig. 5) - Set to adjust your
Guide). During the call, various functions of the IQ750EHS will be
disabled or modified to protect the wireless headset user's privacy while
maintaining their control of the call, as follows:
1. The MUTE Key will not respond (use the Headset's mute function
instead)
2. The Handset, if lifted off the cradle, will not interrupt the headset and
cannot disconnect the call if replaced in the cradle. There will be no
audio to or from the handset.
3. The red indicator on the HANDSFREE/HEADSET Key, when ON, will
signify that the telephone is in use. However, pressing this key will
not disconnect the call.
The telephone will resume its normal functions as described elsewhere
in this manual when the call on the wireless headset is terminated or if
the telephone is connected to a corded headset.
On Line Indicator
The OLI will be illuminated whenever there is a call on the telephone.
Silent Ringing
Designed for call centers or any application where call-related noise is
to be kept to a minimum, this feature allows incoming calls to ring
silently; the operator is aware of the incoming call, but the telephone
does not add to the room noise even when ringing.
To use the telephone in Silent Ringing mode:
1. Set the Ringer Volume Switch to the OFF position (signified by the
square symbol without a bell symbol inside it)
2. Put your Headset on and wait for the next incoming call
3. When a call arrives, the Ringer/Message Waiting Indicator will flash
and the operator will hear the ringing tone at a low level in the
Headset
4. Press HANDSFREE/HEADSET to answer the call.
ALERT LIGHT SUPPORT
- The IQ750 or IQ750EHS is designed to
support the "Alert Light" available on some Headsets. When pressing
HANDSFREE/HEADSET on the telephone, the "Alert Light" indicator on
the Headset will be illuminated, signifying that the user is on a call. This
feature can be used effectively in call centre applications so that the
user's colleagues will be aware that the user has a call in progress.
CALLER ID DISPLAY
When an incoming call is received, information including the Caller's
name, number, date & time will be transmitted to your Caller Display
Telephone between the first and second rings. The Caller's name will
