Figure 5. Initial Offset Tuning Screen
The instructions are to ensure correct operation of component hardware and that when the initial offset
tuning is performed there is no human interference as this ensures greatest sensitivity of proximity detection.
The instructions are to twist the rotary encoder, clockwise and counterclockwise and to click the button and
place the PCB on a surface free from human interaction before the timer counts down to 0. After clicking the
button there is approximately a 5 second delay of which a countdown is displayed – this gives you time to
place the PCB on a surface away from interaction. The countdown screen is shown in Figure 6.
Figure 6. Countdown Screen
Once the countdown has elapsed the device will enter the tuning state for approximately 1 second – after
which tuning is complete and system operation is resumed i.e., the device will display a success message
and the LED should come on while the buzzer sounds (Figure 7) and then enter a low power state.
