8.1.1 Charging the Accumulators
You must charge the accumulators of the Sunny Beam in the following cases:
• Message on the display that the state of charge of the accumulator is too low.
• The display does not switch on, although the accumulators are correctly inserted.
You have three options for charging the accumulators:
• Place the Sunny Beam in a location with a lot of daylight. As a result, the Sunny Beam charges
the accumulators using its integrated PV cell.
• Using the USB connection cable, connect the Sunny Beam to a computer that is switched on or
a USB hub with its own power supply. To disconnect the Sunny Boy from the computer again:
– Remove the Sunny Beam using the "Safely Remove Hardware" icon in the task bar of the
computer.
– Unplug the USB connection cable from the computer and the Sunny Beam.
• Using a USB plug-in power supply, connect the Sunny Beam to a socket-outlet.
During the charging process, the Sunny Beam displays the animated accumulator symbol until the
accumulators are fully charged.
