 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.<br>
 If an item has a numeric value selectable by the user, the numeric value can be changed by rotating the knob. Some items have multiple choices (selections) or submenus (sub-items) available and those are accessible by pressing the knob.<br>

+There are two modes of operation<br>
+(A) contact discharge<br>
+(B) air discharge.<br>
 <br>The default mode is the contact discharge. The sharp conductive tip (electrode) is used for contact discharge and should be placed in the red socket at O-ESD output. For air discharge the rounded conductive tip (electrode) is used and it should be placed in the black socket. O-ESD is intended for use with only one conductive tip (electrode) inserted at a time and with the appropriate mode of operation selected.<br>

 (1) The first (top) item on LCD is the battery status. It displays the minimum of relative voltages of the two batteries. If the voltage of a battery drops below 3.5 V, the battery status displays that recharge is needed. Note that O-ESD will work even with very low battery voltage that may irreparably damage the batteries. Battery status has a submenu that presents extended information about each battery.<br>
