The Trigger function is not enabled in the default setting. This means that the LEDs are “ON” and ready
to scan until the trigger mode is set by the S8 command.
Once in the trigger mode, the host can trigger the unit by sending a <ESC> Z <CR> command. (See
Scanner Timeout to establish the length of time the scanning light remains ON after the trigger is
activated.) A hardware trigger can also be used to turn the scanner ON.

The operation of the scanner in the various read modes is described in the table below. The “Continuous
Read” mode is helpful in positioning the scanner for optimum reading. In “Continuous Read,” the
scanner’s buzzer functions like a Geiger counter, sounding the most active at the position achieving the
greatest number of good reads.
