External Components
As shown on the bottom view of Figure 1, the assembly includes a connector for the push-to-page
operator, a hookswitch and handset connector, and a connector for the RTU connection. When the
handset on the front of the enclosure is lifted from the cradle or replaced in the cradle, a hookswitch (a
magnetic reed switch) signals the appropriate status to the microcontroller within the assembly. In the
center of the front panel, the GAI-Tronics nameplate conceals the User Level Adjustment control.
