connector J5, with the marking facing up.
• Turn off and turn on the kit by touching the
power button twice.
• Test BTN 2; SmartSense
TM
Auto-tuning
compensates for the change in capacitance.
• Repeat with other external capacitors; BTN 2
works with up to 40 pF of parasitic capacitance.
Note* : The power button is set to be less responsive than the other buttons to prevent false starts of the kit.
Once the kit is powered on, the power button is more sensitive to enable easy power cycling.
• Remove the external capacitor.
• Place the 1 mm overlay over the buttons.
