Handling Lamp LED 10.2
Do not expose lamp to direct sunlight. Remove the basement
cover (magnetic attachment!) to get access to the switchboard.
LED Indicators, switch and loading connection are now acces-
sible.
With t h r e e p o s s i b l e p o s i t i o n s o f t h e s w i t c h the
lamp provides f i v e f u n c t i o n s :
Intermediate position of the switch:
1. Function: Checking external power supply
In this position the loading connector
has no connection to the internal battery.
Connection of an external power supply
through the loading connector will
illuminate the LED indicator bright
yellow. If the indicator is not illuminated
the external power supply is damaged.
(For example: damaged solar module,
damaged connector, broken cable.)

2. Function: Charging storage batteries
Insert the plug of the module cable into
the socket of the lamp and aim the solar
cells at the sun.
You can load the internal NH-batteries
of the lamp in this position. Depending
on the loading status of the batteries a
loading current of about 420 mA will
adjust automatically.
An automatic cut off of the loading current is not part of the
design due to the low current of the solar module of 420 mA.
There is no danger of overloading the NH batteries.
Attention:
In order to maximize the durability of the
rechargeable batteries you have to
avoid frequent loading. Only charge
batteries when
red LED
(low battery
warning shows up.
When the red LED shows, switch off the
lamp. If the lamp is not switched off,
power will be cut automatically and the
green LED is extinguished. The lamp can be switched on
again only after the batteries have been fully loaded.
Loading time is between 6 and 7 hours, depending on the
radiation of the sun.
After charging you have to bring the switch in the interme-
diate position.
With higher charge currents (> 0.5 A), reverse polarity or a
short circuit, an internal fuse interrupts the connection to the
internal battery until the problem is fixed.
This cut off is indicated by an increase in the luminosity of the
yellow LED. After fixing the problem, the fuse goes back to
sleep mode. This is shown by reduced brightness of the yellow
LED.
3. Function: Operating external devices
Collection of energy from the internal battery (3.6 V-2, 7 Ah) is
also carried out in this switch position. External devices such as
radio and others can be connected.
(Max power consumption 0.5 A)
With an increased power consumption, as well as a short cir-
cuit, the internal fuse interrupts the circuit and the yellow LED
goes dark.

In addition the little green LED is now
illuminated. The charging socket is cut
off from the inner circuit.
In this position no external use is possible! This circuit is an
overload protection for the internal battery.
With a complete charge the lamp will have light for a maxi-
mum of 12 hours. After 10 hours the brightness reduces
slowly until finally the red LED gets illuminated (low battery
warning).
After use switch off the light to avoid needless current
drain!
5. Function: Alarm: “low battery”
The lamp has an integrated alarm
system. If the battery gets low, the
red LED
lights up. The lamp should now
be switched off and the storage batteries must get charged
(function 2).
Recommendation:
For a better illumination of the working area
it is recommended to put up the lamp with
the strap. Thus the light beam is directed
downward.
Solar Module Handling
Cleaning
Scratches and dirt on the surface of
the solar cells must be avoided, since
they directly affect the performance.
To clean the surface only use pure
water. Do not use cloth for drying.
The cleaning may take place only in
the cold state of the module (in the morning), otherwise there
is a danger of destruction!
Keep connectors and sockets clean!
Alignment
Position solar cells of the module at a 90° angle to the sun.
Align module about noon (12.00 h). Position can be maintained
for the whole week. Use angle on the back of the module to
bring it in the desired position.
Avoid shadow on the solar cells (e.g. by trees, houses) during
the course of the day.
Note: High surface temperatures – up to 90°C! Don´t touch!
Theft
To prevent theft it is recommended to store the module in a
safe place.
