① The remote control of the projector does not work and is not sensitive.
First, make sure the remote control light is on. Then replace the batteries.
② Two P40 projector's remote controls have operation interference
The remote control needs to be bound to the projector (one-to-one binding), and this method is applicable to the signal interference problem of the remote control that comes with the original product:
In the projector off state (the power button shows red light), use the remote control to point at the projector device, long press the ”menu“ button on the remote control for more than 10s until the projector is switched on and there is a screen (the power button shows blue light), indicating that the binding is successful.
A remote control binding A Projector
B remote control binding to B Projector
Note: Please switch off both projectors first. Then you need to do the above steps to blind separately. （Don't do them at the same time）
③ The new replacement remote control does not work for the projector.
The remote control needs to unbind the original remote control and pair it with the new remote control, this method applies to the new replacement remote control does not work:
When the projector is switched off (the power button shows red light), use the remote control to point at the projector device, long press the “home” button on the remote control for more than 10s until the projector is switched on and there is a screen (the power button shows blue light), which means that the pairing is successful.
1. If the remote control light still does not light up or is not sensitive after replacing the batteries, or the remote control light is on but still does not work after pairing, then you need to replace the remote control.
2. If the pairing or blinding is incorrect, please switch off the machine and try again.
