OBJECT DETECTION DEVICE

An object detection device located behind the window initiates the scanning

process. The device is active as long as power is applied to the unit. When the

device detects an object, the green LED will flash. When the laser decodes a bar

code, the scanner transmits the data to the host system and emits a beep to

show that decoding is complete. The object detection range is configurable for

two ranges.

• Short Range Activation

The object detection device initiates the scan process if it senses an

object anywhere from the face of the window out to

approximately 4" to 7".

• Long Range Activation

The object detection device initiates the scan process if it senses an

object anywhere from the face of the window out to

approximately 9" to 13".

If the object is removed from the field during the scanning process, the laser

turns off and the scanner re-enters "standby" mode. However, if the object stays

in the field, the laser remains on for up to 2.5 seconds trying to detect another bar

code. If the scanner does not detect a bar code, the scanner re-enters "standby"

mode. To reactivate the scanning sequence, remove the object and present

another.

If the same symbol stays in the field after a successful scan, the laser stays on

for approximately 7.5 seconds and then turns off. This prevents unintentional

reads of the same bar code. To read the same symbol more than once, remove

the object from the scan field for approximately 1 second and then present the

symbol again.
