    When power is initially applied, the MT780 is activated and begins the process of initialization. Once initialization (duration ≦ 10mS) is completed, the MT780 emits a power-up beep, enters Standby Mode and is ready for barcode scanning. The MT780 will enter Sleep (Idle) Mode and output a Power Down signal (Active high) after a programmable time period has elapsed without any activity.
