The 7104A voice terminal is powered by the tip and ring leads. Battery power is used for some

circuits during the on-hook state when loop current is not available.  The battery power is pro-

vided by four 1.5 volt AA batteries.  The batteries are contained in a battery pack that is accessed

through the rear end cap.

The 7104A voice terminal cannot be used as an emergency station during power failure transfer

conditions.

The 7104A voice terminal is not FCC registered.

This voice terminal is compatible with the inductively coupled hearing aids prescribed by the FCC.
