Initial setup

The IR remote controller board can be set up as follows:

1.

Remove the board from the enclosure using a flat head screwdriver to separate the two

parts of the key fob enclosure.

2.

Install a CR2032 battery by sliding it into the battery retainer on the bottom side of the

PCB with the battery +ve terminal on top, as indicated on the retainer.

3.

Place the board back inside the upper half of the enclosure containing the slot for the

carbon contact pad such that the contact switch footprints on the top layer are aligned

below the carbon contact pad.

4.

Snap fit the lower part of the enclosure by applying gentle pressure all around so that

the two pieces lock into each other.

5.

Now the key fob can be used to transmit the pre-programmed IR RC5 commands used

to control the fan speed/dimmer intensity and it's ON/OFF state.
