IR Remote Operating Instruction

1．Firstly remove the plastic film in the rear board of the remote board.

2．The A, B, C, D signifies the A, B, C, D output.

3．If you want to select the Signal source to output A, press the A key directly. Repeat pressing the A key can switch the signal to the output. For Example,if you like to switch the input 2 hd source to output A,only press the "A” key repeatedly until you see the LED tube showing "2".

4．The plastic film is strongly advised to remove it when the remote is not used for long time.
