Authenticate hologram
1 Look at the hologram. You should see the Nokia connecting hands symbol from
one angle and the Nokia Original Accessories logo from the other angle.
2 Angle the hologram left, right, down, and up. You should see 1, 2, 3 and 4 dots
on each side respectively.
However, this is not a total assurance of the authenticity of the battery. If you cannot
confirm authenticity or if you have any reason to believe that your Nokia battery with
the hologram on the label is not an authentic Nokia battery, stop using the battery
and take it to the nearest Nokia authorised service centre or dealer.
