Quantec Corridor Display - No Controls

A 16 character x 2 line display used to indicate incoming calls in corridors, staff rooms, nursing stations, etc.
Shows call type, call location and (depending on the device used to make the call) the User ID or name of the person calling.
Highest priority calls are shown first with a message saying how many calls are waiting.
Flash and sounder rates intensify to reflect the urgency of incoming calls.
Adjustable contrast and volume controls.

This version works as a normal quantec display but has no cycle buttons to view stacked calls or to manually accept a call from the display.
