Panel Units (Optional)
It is possible to install up to 3 key panel units (KPUs) or 2 display panel
units (DPUs) in the phone. Each panel unit offers 24 additional keys,
allowing you to store the most frequently used phone numbers and
features for quick access.
All keys on the optional key panel unit or display panel unit are program-
mable shortcut keys. For a description on how to program the keys as
shortcuts, see 14 Shortcuts on page 84.
Note:
It is not possible to have both KPUs and DPUs installed on the
same phone.
Key Panel Unit (KPU)
For KPUs, you need to create and print your own key panel desig-
nation cards with the names or numbers of the shortcuts. You place
the cards under the plastic designation cover of the KPU.
Use the Design Card Manager (DCM) tool to create your own
designation cards with shortcut keys. The latest version of the DCM
tool can be downloaded from www.aastra.com. For more informa-
tion, please contact your Aastra Enterprise Certified Sales Partner.
Display Panel Unit (DPU)
DPUs are self-signing, meaning that the name, number, or function
that is programmed to a certain key, will be shown in the display
next to the key.
