1.4 Factory Default Configuration
When shipped, this kit is stuck with the 2 mm overlay; switch SW1 is in Toggle On position and
switch SW2 is in Sleep Off position. The LED is expected to turn on when the corresponding button
is touched. The kit is configured to provide an approximate battery life of one year in standby mode.
If deep sleep mode of CapSense controller is enabled, current consumption can be reduced to 100
nA and the battery life increases accordingly. The deep sleep mode is not enabled in this kit as a
host controller is recommended to enable this mode.
Note The kit is in standby mode when the CapSense controller based power button and the
demonstration buttons and LEDs are in inactive state.
