Setup checklist

Before expanding your system or installing for Centrex, review the installation checklist. If you have Centrex, contact your local telephone company for further information about Centrex service.

The phone number for line 1 must be the same on all phones in order for the intercom and page features to work.

Determine the number of phones that will be on the system.

Identify the phone that will be the console phone.

Identify the private line for the console phone. The console phone must have its own private line. This line is not shared with any other phone.

Follow the regular installation instructions in this manual.

Enable the console phone.

Store the Centrex pickup codes and the seven-digit phone numbers in one touch locations. (See One touch operation beginning on page 55.)

Enable the console phone

Determine which phone will be the console phone for your system and program the console following the directions to Set this phone to be the Centrex console phone on page 41. It is recommended that Line 4 of the console be programmed as a private line, to make sure a line is available for Centrex access.

Console operation

Once another system phone has enabled its delayed ring, the console phone will receive those calls. All the 974 features work in the same manner as described in this manual.

The console phone can pick up other Centrex lines through Centrex switching. You can store the Centrex pickup codes and the seven-digit phone number of each station, except for the console phone, in the one touch locations.
