Reolink: Remove CMOS Battery

This method clears stored settings, including passwords:

1. Turn off the DVR and unplug it.
2. Open the case and locate the coin-sized CMOS battery on the motherboard.
3. Remove the battery for about 5–10 minutes.
4. Reinsert the battery and power the device back on.

This resets system memory and may restore default settings.
