About A10  Wifi-display Function

With the development of science and technology, in the current Bluetooth function, it is no longer used for Bluetooth to transfer files. The role of Bluetooth is only to transmit sound. The Bluetooth file transfer function has been replaced by APP.

Wifi, Bluetooth, wifi-display (airplay, Miracast, DLNA) are all different functions. The effects are different.

   wifi-display function, the projector displays the image and sound of the mobile phone screen through the mirroring function of the smartphone. This is not achieved using the Bluetooth function. It is achieved through the screen mirroring function that comes with the phone.

Note: Not all Android smartphones support the screen mirroring function. For smartphones that support screen mirroring, there are options similar to this in the "Settings" or "More Functions" options of the smartphone, for example: "Screen mirroing", "Wifi-display", "multi-screen", "screen projection", "play to", "media output", etc.

If the projector's pre-installed screen mirroring app is not compatible with your Android smartphone, you can also download and install Airscreen, happycast and other apps that support wifi-display on the projector.

Tips：

Some video apps with copyright protection cannot support wireless projection from other devices to the projector. For example, Netflix, iTunes Movie, Google Movie, Amazon Prime do not support this function on some smartphone and computers. All Android system projectors on the market are the same.

X20 Series Projector Maintenance Guide

1. How to solve the problem of remote control not working?

1.1 The projector comes standard with a 2.4G wireless remote control. If the remote control does not work, you need to re-operate the remote control to pair with the projector.

The operation method is to take out the battery of the remote control, start the projector, wait for the projector to turn on, then move the remote control close to the projector, and then install the battery of the remote control, and the remote control will re-pair with the projector.

1.2 One remote control can only correspond to one projector, and cannot be used for two K45s at the same time.

1.3 If the pairing is unsuccessful, replace a remote control and try again.

1.4 If the replacement of the remote control still fails, it may be that the cable between the remote control receiver and the motherboard is loose. Reconnect the cable between the receiver and the motherboard.

1.5 If there is still a problem, there may be a problem with the remote control receiving circuit board or the main board. Just replace the corresponding parts. There is a disassembly video guide below.
