7.5.2 Battery Symbol/Charging the Batteries
The battery symbol indicates the state of charge of the Sunny
Beam batteries. If the state of charge of the batteries is too low, a
short acoustic signal will sound as soon as you use the Sunny
Beam. The Sunny Beam also displays an additional message.
If you are charging the batteries via the Sunny Beam USB connection, the Sunny Beam will visualize
the charging process by displaying the battery symbols one after the other.
Charging the batteries when there is sufficient daylight
Put the Sunny Beam in a place with as much light as possible, ideally in direct sunlight, so that sufficient
light hits the solar cell.
Charging the batteries when there is insufficient daylight
Connect the Sunny Beam to a USB port on the computer with the USB connection cable which is
delivered with the Sunny Beam. The computer needs to remain switched on. If no computer is
available, use the USB plug-in power supply. The USB plug-in power supply is not included in the
scope of delivery (see section 14 "Accessories" (page95)).
