1. 注意摄像头以及codec上都有irsensor, 如果摄像头的sensor enable以后，codec会自动disable。
Check the Configuration -> Cameras and check that the IRSensor is set to On.
Check Configuration -> System Unit and check that the IRSensor is set to Auto.
2. 遥控器上可以调节short range/long range -switch inside the battery compartment.
如果距离短，可以调整为short range
3. 如果连接了触摸板，那么遥控器是不好用的
4. 可以在命令行下看到遥控器键入的效果：
Confirming the key presses are received
You can confirm that key presses are being received by the codec in the system by using the command
line interface. Login as admin using SSH and enter the command: xfeedback register /event
Result:
xfeedback register /event
** end
When a key is pressed you will now see an event generated in the SSH session output. The actual
key presses are masked by ”*” for privacy, but this output will confirm that input is received from the
remote control.
OK
*e KeyDown Key: “*”
** end
*e KeyRelease Key: “*”
** end
*e KeyDown
5. 最后可以尝试更换电池
