Theft detection

This program judges that a theft has occurred if power supply (from the contactless charger) stops

and does not recover within one second. It displays the Stop Theft Monitoring screen.

Alarm (upon theft occurrence)

After detecting a theft (displaying the Stop Theft Monitoring screen), the program waits for four

seconds and then sounds a warning pulse buzzer (with a width of 20 ms and a period of 100 ms)

for five seconds.

Then, the warning buzzer sounds for one minute.

After this one-minute period, the warning buzzer will no longer sound.

Note that after the buzzer sounds, the terminal enters unlocked state.

Power recovery during alarm issuance

If the power supply recovers during the alarm, the program judges that no theft has occurred.

More specifically, the following steps are performed:

1. The warning buzzer stops.

2. The Stop Theft Monitoring screen disappears.

If the user is entering the secret number on the Stop Theft Monitoring screen, the screen

disappears without waiting for the completion of entry.

3. The theft monitoring service restarts theft monitoring.
