To turn on your Handheld Transmitter (HHT), do the following:

1. Press and hold the red button.
2. Press and hold the green button.
3. Release the red button.
4. Release the green button.

After turning your HHT on, the device shows a logo for several seconds or until a button is pressed, after which the device shows its primary functions.

Each symbol on the two screens indicates the function of the nearest button. Each button corresponds to a specific digital output on the receiver. The outputs are activated as long as the button is held down. This behaviour can be modified by customizing the firmware at customer request.
