How do you use the HDR?

Here is my procedure to use the HDR, it's a step by step guide I used at first to get familiar with using the device. Now I no longer need it, but I still use the HDR as follows:

1. Plug in the unit.

2. Turn ON the Yellow switch and wait for 2 minutes with the witness well empty, in order to clear it.

3. Put the double terminated quartz crystal or some other item related...
