GLEDOPTO GL-C-009P How to Reset?

Hi Folks, my GLEDOPTO GL-C-009P stopped to works, so I want to pair again, but the only place I found information about the reset is it below, I tried this but did not work, could you guys give some advice?

Pairing

  1. Switch on your device.
  2. Now switch off and on within 2 seconds.
  3. Repeat off/on four times.
  4. Reset is done when the device is switched on in the fifth time and the light stays on after blinking 4 times
