Check that the AC outlet voltage falls in the range
of 100-240 Volts AC. Verify that the cord and plug are
appropriate for your AC source.

Versa.
2. Plug one end of the AC power cable into the AC adapter and the other end
into a properly grounded 120- or 240-volt wall outlet.
Note:
The AC power cable type that your system uses
depends on the country where you are using it. Contact the
local dealer to purchase the correct power cable.
