GENERAL INFORMATION
1.1 GENERAL DESCRIPTION
The TD monitor is a solid state unit for use in industrial, commer-
cial and data display fields, where reliability and high quality
video reproduction are desired. Applications such as remote moni-
tor for computer terminals and airline flight arrival/departure
displays are ideally suited to this unit.
1he TD monitor has a single plug-in circuit board with silicon
transistors. The unit is equipped with differential input for
composite video signal to minimize hum and other extraneous pick-
up on long video feed cables. The 23 inch cabinet is available
with or without studs for versatile mounting configuration.
