Chapter 2. Installation

The Passcode, the Unit ID, and the Control Port settings are stored in a nonvolatile memory. This ensures that they are operable for subsequent power-up sequences.

Normal Power-Up Procedure

After the unit has been put into operation with the initial power-up and initialization, subsequent power-up procedure includes only the Power- Up Self-Test followed by the request for a passcode (password) if this option was selected during initialization.

Use the number keys to key in the previously recorded passcode and press Enter.
