Your Extension’s Accessories
You may also add the following optional accessories to your exten-
sion:
•
One or several DBY 419 01 satellite(s) or add-on key panel(s).
From one (1) to four (4) satellite(s), each one offering 17 repertory
keys that may be programmed with your most often used internal
or external telephone numbers or telephone service codes.
• A DBY 420 01 add-on interface module.
As the case may dictate, this module may enable you to connect,
for example, an external ring device, or an external device visually
indicating your extension’s free, ringing, or busy status.
This accessory is generally for alarm or security extensions.
• A headset.
This can allow you to process your calls using a headset, rather
than in handsfree or handset mode.
This is especially useful for ICD group agents who process
phone calls all day long.
This section provides you with all of the instructions necessary for
installing these accessories. It also includes the instructions for using
a headset.
For the programming and use of the add-on key panels’ or satellites’
repertory keys, see the “ Programming Your Extension ”,
“ Operations for Outgoing Calls ” and “Group Services” sections.
Note: You may add up to 4 satellites on your extension
without requiring any additional power supply units. All of
the satellites are powered from your extension, which is
powered through the telephone system.
