When connecting one or two optional key panels to your telephone the DBY 409 01 key panel may be used. No external power cables are required for this key panel, as power is supplied from your telephone.
However, if three or four key panels are to be connected, then the DBY 409 02 optional key panel must be used for all key panels connected to your telephone. Whereby, a 24 V a.c. power cable must be attached to the first key panel connected to your telephone to provide power to all key panels.
