Installing Your Extension

Your Dialog 4223 Professional is usually installed by your system 

administrator.
However, this section provides you with all of the instructions for 

installing your extension yourself and for maintaining it.

Installing Your Extension’s Telephone 
Cords

Your extension is connected to your facility’s telephone facility 

through a line cable that connects into the RJ12 female jack 

labelled LINE, located on the underside of your extension.
The handset cord is connected to the RJ12 female connector 

labelled HANDSET located, once again, on the underside of your 

extension. This may be installed so that it comes out of either the 

left or right side of your extension. In the first case, the handset 

cord should be inserted in the slot made for this purpose, as 

illustrated in the diagrams below.

When it is necessary to disconnect a cord, it is recommended that 

you use a screwdriver to depress the release tab on the RJ12 male 

connector.
