Part 1. WatchON
[Q50: WatchON]
Q : The operation of remote control in WatchON is poor. What should I do?
A : Please check the following points.
1. The TV is controlled by the lrLED which is located on the top right side of the Galaxy S4.
For best performance please point your Galaxy S4 at the front of the SET TOP BOX or TV 's "IrLED sensor part "
2. Because IrLED is a technology that uses infrared, if the surrounding walls are for example grey ,
the operational distance may shorten. (In case of the achromatic color, the infrared reflection is reduced)
3. Some fluorescent lamps may affect the remote control feature – try adjusting the lighting in your room if possible
[Q51: WatchON]
