To start a completely new program the existing program must be erased by holding down
the SAVE button for 3 seconds until the RUN LED flashes.
When a program is running the duration between each step is half a second. For
a longer ON or OFF period simply press the SAVE button more than once during
programming. For example, if OUTPUT1 LED is green and the SAVE button is pressed six
times, then output 1 will be on for 3 seconds when the program is running.

The polarity of the outputs can be reversed during programming so that motors can be
run forwards or backwards. The following program runs a motor forwards for 3 seconds,
stops the motor for a second, then reverses the motor for 3 seconds:

Note: when reversing an output it is advisable to include an OFF step between the
forward and reverse steps to protect the IQ from current overload.
