How do you turn off the seatbelt alarm on a bt50?

To temporarily deactivate the belt minder, turn the ignition switch to ON, fasten the driver's seat belt for about 2 seconds or longer, then unfasten it within 20 seconds. The belt minder will be deactivated temporarily, until the ignition switch is turned to ON next time.
