When power is initially applied, the MT684 is activated and begins the process of
initialization. Once initialization (duration≧1000mS) is completed, the MT684
emits power-up beeps, enters Standby Mode and is ready for barcode scanning.

By default MT684 is in Continuous Mode, in which it takes at least 80mS for
MT684 to complete a scanning operation (decode + data output + buzzer signal).
When MT684 is configured in Trigger Mode, the Trigger signal must be kept low
for at least 20mS to activate scanning. Therefore in Trigger Mode it takes at least
100mS for MT684 to complete a scanning operation (trigger signal + decode +
data output + buzzer signal).

The minimum duration of initialization is 1000mS.
In Continuous Mode (default), the minimum duration of scanning operation is
80mS.
In Trigger Mode, the minimum duration of valid Trigger signal is 20mS and
minimum duration of scanning operation is 100mS.
