1、KI-1683C TC4222 Vacuum Fluorescent Display Installation RAULAND-BORG CORPORATION l 3450 West Oakton Street, Skokie, Illinois 60076-2951 l (847) 679-0900 General Information Description Planning The TC4222 Vacuum Fluorescent Display (“VFD”) may be used as an alternative to the LCD displays of the Tel

2、ecenter Systems. The TC4222 is larger and brighter than an LCD module and, being wall-mounted, can serve as the display for several nearby administrative phones. It is compatibIe with Telecenter IV, Telecenter V, Telecenter TCS, Telecenter System 21, and Telecenter 1100 systems. Attachments IL0364 (
