MESSAGE WAITING LIGHT COMPATIBILITY
No installation settings are required to enable the feature. If you have a PABX system, the red lense in the top right hand corner will light when there is a message waiting. If the light does not function correctly, your IQ750 may need an optional circuit to be added to make it compatible with your system. If you have a Centrex system (eg. Spectrum) the Caller key indicator and the “Mail” (envelope) icon will flash and “MESSAGE WAITING” will be displayed. To retrieve your message, consult your voice mail system user guide.
HEADSET MIC ADJUST CONTROL
This control allows many different headsets on the Australian market to function correctly with the IQ750 telephone by adjusting the Headset Microphone sensitivity. The control is located on the underside of the telephone (see Figure 8). The adjustment can be made by a small screwdriver or similar implement that will fit into the control slot. Please see Table 1 as a guide to the correct settings for some popular Headsets.
