Charge the battery
The battery may not be fully charged at first. It is
advised to fully charge the battery.
Please use either the provided power adapter or
one of the recommended power adapters to
charge the battery.
It is also possible to use the supplied USB to DC
2.1mm cable to charge the battery from a power
adapter with a USB socket. The power adapter
should be capable of supplying at least 1.5A at 5V
otherwise it will take much longer to fully charge
the battery in Nexus DSC.
Connect the power adapter to Nexus DSC and
plug the adapter into a power point.
It is recommended to keep Nexus DSC turned off
during charging to reduce charging time.

Do not connect Nexus DSC to an external
power source that is not within the
specified voltage range. Nexus DSC has
internal over-current protection but it is
safer to use it with the power source
specified.
