2. To activate programming mode, use a small screwdriver to hold the pushbutton
down for 3 seconds:
All the LEDs will then light up to indicate programming mode.
3. Pressing the button briefly changes the address one step at a time, allowing you to
cycle through the addresses shown below
4. Hold the pushbutton down for 3 seconds again to save the address.
The new address is saved in the non-volatile area of the memory.
All LEDs will then switch off.
The addresses are indicated in code form by the following LED sequences:
Bus address LED 1 LED 2 LED 3
Ready for programming ON ON ON
0x38 ON OFF OFF
0x39 OFF ON OFF
0x3A OFF OFF ON
