1. From IGN1 switch ON, Warning lamp for 1 sec (DUTY 50%) and Chime buzzer for 6 time every 1sec. (in case of S/BELT unfastened state) But, within 6 sec in the S/BELT fastened, the Chime buzzer output is stop, and Warning lamp is the remaining time.
2. Lamp and Chime buzzer become output stop when IGN1 is turned OFF within 6 sec-output.
3. If vehicle speed over 10 Km/h, Warning lamp and Chime buzzer are work for 1 time when Seat belt unfastened after IGN ON.
4. If vehicle speed below 5 Km/h or IGN OFF or seat belt fastened, pattern is stop when pattern is running.
5. Seat belt fastened→unfastened when IGN1=ON state: if vehicle speed over 10 Km/h, 1 time output. And if vehicle speed 5~10 Km/h, Warning lamp for 1s (DUTY 50%) and Chime buzzer for 6 every 1s. If vehicle speed less than 5 Km/h, Warning lamp for 6 every 1s (DUTY 50%)

1. Warning lamp lights continuously every 1sec (DUTY 50%) for 6 sec when IGN is turned ON under unfastened seat belt.
2. Warning lamp is turned OFF when IGN is turned OFF within in time.
3. When IGN is ON under unfastened seat belt, the warning lamp lights. The lamp continues to light for remaining time of 6 sec when seat belt is fastened within 6 sec. The lamp is OFF if seat belt is fastened after 6 sec.
