a) Use one hand to hold the crystal holder and the other hand to hold the
transformer housing (see Figure 3-12 ).
b) Turn the transformer housing clock wise by 90 degrees and slide it slowly to

plastic bottle for the coupling fluid.
Note
Do not press the Kapton tape while spreading the coupling fluid.
6. Wait for 30 - 60 seconds to let the coupling fluid spread more evenly on the surface.
