Changing the Battery
The device is provided with two sources of energy:
- solar energy, which is absorbed by the solar panel above the display.
- a 1.5 V battery (LR 1130).
If the quality of the image in the display begins to deteriorate, it is a sign
that the power supply is too low. Recharge the supply via the solar panel
above the display by exposing the front side of the device to sufficient light
(sun, bright lamp, something similar) or change the battery:
1. Carefully loosen the screw on the rear side of the device and remove
the cover.
