Getting Started
The MBU 400 must be set up and configured prior to its first use. This section
describes the behavior and start up screens you may see on the 420d handset when the

The Lights on the front of the MBU 400 indicate the current status. When starting the

To configure your MBU 400 for internet calls using the handset, see Configuring
Your Phone for First-Time Use on page 22, or ask your System Administrator for
assistance.
