10.2.3 Audible Indicator
The beeper can be disabled by using a configuration command. Refer to page 4-6
for information on setting beeper volume. The beeper also sounds on power-up or
reconfiguration as an audible self-check of software configuration.
10.2.4 Mounting Inserts
Inserts are molded into the housing to retain mounting screws. Inserts are available
for metric (3.5) or SAE (#6-32) screws.
10.3 Operating Theory
Figure 10 presents a block diagram of the basic SCANTEAM 3700 Wedge operation.
The SCANTEAM 3700 Wedge looks for data input from the scanning circuitry, which
includes the LED reflector (illuminates the bar code target), the CCD sensor and
imaging lens (focuses the scattered optical energy from the bar code symbol), and
the peak detectors and comparator (generates a digital representation of the bar
code symbol to send to the microprocessor).

Figure 10. Basic Scanner/Decoder Operation
While scanning, the 3700 Wedge evaluates scanner data for a valid bar code
symbol. If a valid bar code symbol is seen, data is placed into the output queue
where it is transmitted to the host.
