4 Multi-Handset Expandability
Your phone supports up to 4 handsets
(including any handsets supplied with your
phone). You can now place a fully-featured
cordless handset anywhere AC power is
available to connect the handset charger.
Up to 2 handsets can be used for an outside
and/or intercom call.
Effective combinations, for example:
- 4-way conferencing (the base, 2 handsets, and one outside line), while on an intercom call
using the other 2 handsets.
IMPORTANT:
• If you purchase a DCX640 extra handset, please register the handset to the original/main
base before use. The DCX640 will not operate until it is registered.
• If you change a Global setting in one handset, you change that particular setting for all
registered handsets. All other settings (not included under Global Setup), must be set
separately through each handset.
1) Connect the AC adapter to the DC IN 9V jack and to a
standard 120V AC wall outlet.
2) Set the charger on a desk or tabletop, and place the
handset in the charger with the keypad facing forward.
(See "B. Install the rechargeable battery pack into the
handset" on page 12).
