Note: The light should now be dark during daylight. The solar module also
has a twilight sensor function. If the solar module is in darkness, then the
voltage of the solar module drops and the light will switch on automatically.
8. The solar module can be placed on the ground using the ground spike.
The position of the spherical joint can be adjusted for best alignment
towards the sun.
Note: Illumination time is highly dependent on the intensity and duration
of sunlight (solar irradiation) during the day. Illumination time is generally
expected to be less during the winter months. Should the light not switch
on on the first evening, please wait for a sunny day.
5. Colour setting
The light has 2 different colour settings. These are selected using the
button underneath the light (Centre). Press the button to select the option
you want.
1. Light color changes every minute
The light color changes every minute slowly between every color.
2. Fix the lighting color
When you want to fix the lighting color to permanent light, please press
the switch on the bottom of the light. To start color changing please push
the switch again.
6. Replacing the battery pack
As a rule, the battery pack must be replaced every 2 years with a new
one of the same size and type. It is a 3.2V/ 400mAh or 3.2V/ 1500mAh
lithium-Fe battery. Replacement batteries are obtainable from your dealer
or the manufacturer (www.esotec.de).
The following is the correct procedure for replacing the battery:
1. Loosen the connections at the bottom of the lamp.
2. Rotate the bottom of the globe counter-clockwise.
3. Disconnect the connector of the battery from the connector on the cable
of the board.
Note: To do this, press the latch down to release the plug connection.
4. Replace the battery with a new, identical battery.
5. Close the lamp in the reverse order used to open it, and remember to
reconnect the solar module cable.
Note: Used batteries, whether rechargeable or not, must be disposed of
in an environmentally friendly manner and should not be disposed of in
domestic rubbish bins. Your dealer is obliged by law to accept old batteries
for disposal.
7. Troubleshooting
Lamp does not switch on at nightfall.
- An ambient light source (e.g. street light) simulates natural light in the
solar module and prevents the light from switching on automatically.
Place the solar module in a darker place.
Lamp does not switch on at nightfall, or switches on only briefly.
- Check the connector plugs on the solar module cable and battery are
properly connected.
- Battery is weak or faulty. Replace the battery at least once every 2
years.
