Expansion key module Mitel M685
You can connect up to three Mitel M685 expansion key modules next to
each other on the right of the phone. The Mitel M685 expansion key mod-
ules has the following properties:
• Three display levels with 28 configurable keys each (84 configurable
keys in total). Three Mitel M685 would therefore give you an additional
252 configurable keys.
• Each key has a LED for visual signalling.
• The keys on the expansion key module support all key types that are
supported by your phone's keys, except operator keys, and operator
queue overview key.
• The configurable keys of the expansion key module are operated the
same way as the configurable keys of your phone.
• The image icons for the busy lamp field keys do not appear on the
expansion key module. The expansion key module shows only icons
with the initial letters.
• The keys must have been configured either by your system administra-
tor or by yourself in the Self Service Portal (see chapter "MiVoice
Office 400 Self Service Portal", page 9).
• If you remove an expansion key module or if you modify the order of the
connected expansion key modules, the key configuration changes.
• The display contrast setting and the display backlight is taken from your
phone.
