Autodial allows you to dial long sequences of numbers using just one or to buttons, allows you to store frequently used feature codes and store station numbers of frequently called telephones.

Autodial can be stored at any programmable button that is not assigned as a line button or other feature, on a secondary level under a DSS button or at keypad keys 0-9.

When stored at programmable button locations, outside numbers and feature codes are referred to as autodial numbers. When they are stored at keypad number locations, they are referred to as direct station selection (DSS) numbers. The light associated with the DSS button is the busy lamp field (BLF) light.


If you wish to program an emergency number and make a test call, the FCC requires that you stay on the line and briefly explain to the dispatcher that you were testing an autodial button. Please make your test call during off peak hours, early in the morning or late in the evening.

Before programming, write down the intercom or outside line you will use as well as the phone number, extension number or feature code you are using.

While programming, fill in the identification strips on your phone and fill out the charts provided in the prinable version of this document for your records.
