NOTE:
Do not use the Auto Answer-All feature when an HFU is connected
to your phone.
Instead, program Auto Answer-Intercom so that the
control unit automatically signals you for an incoming intercom call
and turns off the HFU when the call is completed.

Headset and Headset Adapter
A headset connected to your phone by way of the headset adapter allows you
to handle calls more easily. A headset can be used with all the BIS models,
the 10-button, 34-button, 34-Button Deluxe, SP-34, and SP-34D analog phones
and with the 7406D and 7406D with Display digital phone. There are three
types:
● Model 500A is used with digital phones.
● Model 502A is used with analog phones.
● Model 502B is used with analog phones and the Auto Answer-All feature.
NOTE: The difference between the model 502A and 502B headset adapter
is that model 502B can be set so that incoming calls are picked up
automatically. See “Auto Answer-All” in Section 3, “Reference.”
