PRELIMINARY
DESCRIPTION MOUNTING PARTS
The CRT3 is a dial-less telephone designed for use with
the Rauland Telecenter@ systems. On the Telecenter IV
and Telecenter TCS, it can serve asa single-link or a multi-
link staff phone. On the Telecenter 5500, it can serve as a
common-line staff phone in conjunctionwith an ADS55 10
Console and an RS503 Staff-Telephone Adapter.
In addition to the standard“tip”and“ring”wiring, the
CRT3 has a second pair of contacts that provide a dry con-
tact when the phone is lifted off-hook. This connection
enables the phone to call in when the handset is lifted.
Important: Never connect the CRT3 to the modular
jack of an Administrative Display Telephone: the CRT3’s
extra set of contacts would place ashort across the display
lines.
The telephone comes with the following mounting
parts:
