Getting started
Telephone base and charger installation
Install the telephone base and charger, as shown below. If you subscribe 
to high-speed Internet service (DSL - digital subscriber line) through your 
telephone line, you must install a DSL filter between the telephone line cord 
and the telephone wall jack. The filter prevents noise and caller ID problems 
caused by DSL interference. Please contact your DSL service provider for 
more information about DSL filters.
The telephone base comes ready for tabletop use. If you want to mount your 
telephone on a wall, refer to Wall-mount installation on pages 9-11  
for details.
Plug the large end 
of the charger’s 
power adapter into 
an electrical outlet 
not controlled by a 
wall switch.
Ensure the small 
end of the charger’s 
power adapter is 
plugged into the 
power jack on 
the bottom of the 
charger.
