The O-ESD is powered up (or down) using the toggle switch located on the grip. The O-ESD user interface consists of: toggle switch (ON/OFF), fire button, USB battery chargers (optional), LCD, down button, up button, multi-purpose knob located on the left side of the LCD.
Once the O-ESD is powered-up the splash screen should appear for 1 s at the LCD. Afterwards, the main screen of the O-ESD shows up. LCD has four 20-character lines. Each line stands for one item. Items (i.e., lines) are selected by moving the selector “ > ” using up/down buttons.

Regardless of the winding method, the beginning of the high voltage coil, which comes closest to the ferrite core, shall be inserted in heat shrink tubing and the tubing shall be heated to its final dimensions. The tubing is used to improve the insulation between the wire at the beginning of the coil and other wire layers.
Once a winding layer is completed, it shall be fully covered by layers of insulation paper. The total thickness of the insulating layer must be at least 0.2 mm. The first role of this insulation is to reduce the parasitic capacitances between adjacent wire layers. The second role is to increase the breakdown voltage between adjacent wire layers.

The completed secondary winding shall be covered by layers of insulation paper either fully or only in the area where the primary winding is going to be placed. The main role of this insulation is to increase the breakdown voltage between the two windings.
Once both windings are completed, the insulation from all wire ends shall be removed. Solder the terminals of the primary and secondary windings according to raster view. The beginning of the secondary winding (which is covered by the heat shrink tubing) shall be soldered to the pin denoted by the red circle in raster view.
Insert the two halves of the ferrite core into the coil former shown in assembly of the step-up transformer. The cross sections of the core in the areas denoted by green ellipses should have gaps of 0.25mm to 0.3mm. Cut three pieces of the standard printing paper (80 GSM) paper per gap, and stack pieces to form the gap. It is not necessary to place the paper in the central column of the core.
