Factory Reset 

To reset the module back to factory settings, switch off the power to the module and 
hold down the Push Button. Apply the power and continue holding the push button 
until

 1 flash

 of the led is seen. At this point, release the button. You will see a long 

flash of five seconds. 

The led will begin flashing again. When you have seen 

1 flash

 press the button. You 

will see a long flash of five seconds and then 10 rapid flashes. The reset procedure 
is then complete and the module will restart with factory settings, and run the 4-
aspect signal mode. If you make a mistake programming, simply repeat the process. 

  

Led Connection 

When using leds it is important to connect them the right way around. 

The negative lead (cathode) is identified by a flat on the side of the led body, and by 
having a shorter lead.
