13. Troubleshooting
In purchasing the endoscope, you have acquired a product designed to the state of the art and
operationally reliable. Nevertheless, problems or errors may occur. Therefore, we would like to
describe to you how to remove possible interferences.
The endoscope does not work; nothing is shown on the display:
• The batteries may be empty. Open the battery compartment lid as described in chapter 8 a).
Check the batteries and replace them if necessary.
The preview mode is not displayed after activation. You can only see a black screen:
• Check that your endoscope camera is properly connected to the endoscope basic device.
• Switch off the endoscope, wait for a few seconds and then switch it on again.
No photographs or videos can be recorded:
• Check if the Micro SD card is properly inserted.
• The Micro SD card may be full. Check this by either connecting the endoscope to a computer
by USB or check the memory card in your card reader. Delete some recordings if necessary.
• The partition of the Micro SD card may be damaged. Use your computer or the respective
menu function to format the card (chapter 9 d).
• The Micro SD card may be defective. Check the endoscope with another Micro SD card.
14. Care and cleaning
The product is maintenance-free for you. Never take it apart or open it (except for the procedure
as described in these operating instructions for inserting or replacing the batteries). Repair or
maintenance work must be carried out by a specialist.
A dry, soft and clean cloth is sufficient for cleaning the outside. If the product is more strongly
contaminated, moisten the cloth with a little luke-warm water.
Use a small brush or a cotton swab to clean the camera lens.
Do not put too much pressure on the display; this can cause scratch marks or failures
of the display. Never use any aggressive cleaning agents or chemical solutions. They
may damage the surface of the casing (discolourations).
