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 “

” and “Group Services” sections.
