Programmable Buttons
Your telephone has 16 programmable buttons.The first seven buttons on the telephone are
programmed by the system administrator and cannot be reprogrammed. However, you can
program the remaining buttons for quick access to features or speed-dial entries. See “Using
Programmable Buttons” on
page 16 for instructions.
Software Updates
When the telephone is plugged in for the first time or after a system upgrade, it may update its
firmware. The upgrade process can take up to 13 minutes. During the upgrade, all lamps flash
on and off, and the display shows that an upgrade is in process. Do not unplug the telephone
during the upgrade.
