Description

1） How do you program the 4 colored buttons at the bottom? I wanna program one of them as a back button for kodi.
Answer:
the four color buttons at the bottom can only be programmed as infrared with your TV, etc ... You can program the red one to turn my TV on/off and the other three to switch the TV input and the 3D options ... for the Kodi back button or program the "home" button just above the cursor/OK button in the center

2） Can I use more than one in a small area ? I need to use two in my bedroom. Will they interfere ?
Answer:
It depends:
1) You can use two USB keyboards in a small area at the same time, for each keyboard is connected with different USB receiver that owns specific code value.
2) The IR commonly has similar frequency. At the same time, it also has learning capabilities, so it could possibly take over the duties of another remote if the two devices ( like TV ) are close enough or in a straight line.

3） Without line of sight can I use the keyboard to change channels? Or it is IR based? I plan to put my HTPC behind the tv.
Answer:
Yes you can use this 2.4G USB wireless keyboard without line of sight only if your HPTC, TV box ,etc have USB port.
The only IR functions on it are 4 programmable buttons on the bottom of the remote which you can use for devices like television to power on/off them or to switch their modes. That is to say you can program them any way you'd like.

4） will this work with ps3, ps4?
Answer:
It will work with any USB compatible device.

5） how to do pair it to the nvidia shield tv ?, if i plug the usb it does not recognize it, do i need to do anything else?
Answer:
You are supposed to unplug the receiver and reconnect it, wait for 20 to 60s for the receiver driver to be installed.
Press [OK] and [TV] button at the same time about 5 to 8 seconds to establish the pairing.

6） Does it work with chrome OS devices?
Answer:
We haven't test it for  all the chrome OS devices, but it works with most of Google TV and Android TV.

7） Will this remote work as a universal remote for my TV and PS3?
Answer:
Yes, the USB media keyboard side is powerful and compatible. The other side includes a universal TV/Media remote and Four IR learning keys that you can program them to other specific functions as you like. It is multifunctional largely instead of totally "universal"
