LED flashes [ ] on the front of the unit flash for approximately 1 second every 11
seconds. By dimming the solar cell, the LED flash can be triggered manually.
Battery charging:
• You will find a rectangular black rubber cover on the side of the device [ ].
• Remove the cover carefully and turn it a little to the side. It cannot be removed com-
pletely due to the safety catch.
• Use a 5 V charger with USB Micro-B plug. You can also use the USB port of your com-
puter. Use a USB-A/Micro USB-B cable.
• Insert the Micro USB plug into the charging socket 5. The red LED will flash [ ].
• The batteries are fully charged when the LED lights up permanently.
• Remove the cable and replace the rubber cover.
• The device is now ready for operation.
Red LED-signal during charging with USB:
• Red light flashes during charging
• Permanent red light when batteries are fully charged
Changing the batteries:
It might happen that, after a period of time, the rechargeable batteries need to be ex-
changed.
Make sure that only rechargeable batteries are used. Do not use standard
batteries!
• Open the Plexiglas cover on the top of the device. To do this pry the lid open at the
edges by using e.g. the backside of a knife. Proceed from one edge to the next until
the lid comes off easily.
• Carefully lift up the solar panel. Make sure that the cables are not torn off in the pro-
cess. The solar panel can easily be folded away to the opposite side of the terminals
(Fig. A).
• Under the solar panel you will find the battery compartment.
• Insert a new set of rechargeable batteries. Do not use standard Batteries!
• Pay attention to the polarity. The minus end of the battery always connects to the
spring in the battery compartment.
• Place the solar panel back into the device. Due to the foam rubber there might be a
slight resistance. Press the solar panel gently down by pressing on the middle of the
solar panel.
