Figure 2-4. Installing the Telephone Line
On the back of the Model 400 is an extra female telephone jack labeled
“EXT”. This is provided so that a telephone or other answering device
may be used on the same line as the unit. (It is not necessary to hook up a
telephone for the Model 400 to operate.) This extension jack features Line
Seizure which means that it will disconnect the extension jack when the
Model 400 needs to make a telephone call. To ensure that the unit has pri-
ority over any other device on the line, you must connect all extensions to
this jack. (see figure)
On the unit there are two RJ11C phone jacks:
• The RJ11C jack labeled “LINE”is to be connected to the incoming line
of your phone service, ahead of all other phones or telephone extensions.
• The RJ11C telephone jack labeled “EXT” is to be connected to all
extensions.
