password or RF card):
• Make sure the fingers are clean before inputting the fingerprint.
• Input the fingerprint of the same finger successfully for several times
• Keep the fingers dry as wet fingers may affect the accuracy of recognition.
• To ensure effective unlocking, clean up the fingerprint input area when scanning a
fingerprint. If the fingerprint input area is damaged, stop using it and contact the customer service hotline
for repair.
• Only use 2A batteries that meet national safety standards. The positive and negative poles should be
installed correctly;
• If the Lock will not be used for a long time, remove the batteries;
• Old and new batteries must not be mixed using together.
• Comply with local environmental protection laws to dispose the used batteries;
• If your skin or clothes come into contact with battery fluid, rinse with water immediately. If the fluid gets in
your eyes, rinse your eyes with water immediately and seek for medical treatment afterwards.
