3. How to set the unlock delay time
1). Power-on within 5 seconds, short-circuit S2 up to 3 seconds, the IN-USE indicator
ash.
2). Short-circuit S1 up to 3 seconds, and the IN-USE indicator always light.
3). Short-circuit again S2, at this time,the short-circuit time equal to unlock delay time.
(the IN-USE indicator ashes once per second, Less than two seconds by one second
calculation; The maximum setting time is 30 seconds.)
4). After S2 released, saved unlock delay, and exit the setting.
