4.2 Step-by-step guide
i) First, open up the casing of the LCD remote controller into its top and bottom case using a
screwdriver. To do this, insert the screwdriver into the lower slot and slide it in the outward direction.
ii) Fix the bottom case onto the wall with the 2 wooden screws provided. Then, insert the 4 connecting
wires (from the main board) through the slot on the lower right.
iii) Connect one end in each of the 4 wires to the terminal block behind the top case as shown below.
The wire that goes into the "GND" terminal at the top case must be connected at the other end to the
“GND" terminal at the main board. The same goes for the "+5V", "B" and "A" connection.
iv) Fasten back the top and bottom case into place. Hook the two upper claws into their respective slots
and snap the lower part shut.
5. AUTO RANDOM RESTART
When power resumed, the unit will automatically restart and operate at the previous setting as before power
failure occurred. (Remove jumper at JH/JP1 will cancel the auto random restart function. Please refer to
wiring diagram for the location of the JH/JP1).
