... Refer to the QT102-ISG datasheet for details (see www.qprox.com/downloads). • Insert the battery provided into the battery holder on the E102 board. Ensure that the battery has the correct orientation (negative (-) side to board) or the E102 will not work. • Touch KEY and the LED will light. After the Auto-off Delay is reached (actual time is dependent on Voltage level, Ct and Rt tolerances), the LED will switch off. Default setting: User-set Auto-Off Delay (J3 Pins 1 & ...
