The X500 panel can be reset by sending a text message with '0000' to the sim card in the control panel. Please note this can only be done by a phone number registered in the SMS or call list in the X500 panel.
If you want to reset the system without using SMS, do the following:
- Turn the system off first with the black switch at the back.
- Hold the button at the right side of the panel.
- While holding this button, turn the system on with the black switch at the back.
- Keep the button held until the system beeps twice.
- All settings will be reset.
Important note: This will only set the settings to factory default. All accessories will still be connected.
