The energy of the battery runs off and I connect ithe device in a power supply. After some minutes I turn on the device and I try to put the pin number, but I receive a "incorrect pin number" message. I'm sure the pin I'm putting it's right. It's the second time I had to do a hard reset my device because that. For some reason the PIN are being lost after the device turns off. But this doesn't happen everytime the battery runs off.

  • Hi jethinho,

    We're afraid we are not seeing this same situation on our ZD553KL right now.
    Could you check if this problem is also appearing in the latest firmware version WW-15.0400.1909.516?
    If it is, could you tell us the battery level this problem happens in?

    Thank you :)
