Appendix M — Operational Tips

Do:

• Check inputs (label speed, length, height, etc.) to ensure the desired number of

decodes per label.

• For optimum decodes, mount scanner so that your labels pass through the center of

the depth-of-field (minimum/maximum range). You find the center by moving your

label in and out during a read rate test.

• Avoid excessive tilt, pitch, and skew of the bar code label.

• Check the bar code label for readability by doing a decode rate test. If there is any

question about the label's readability, contact your Microscan representative at

helpdesk@microscan.com.

• After changing any parameter that might affect decode rate, repeat decode rate

test.

• Clean the scanner window with a clean, dry Q-tip or cotton cloth on a regular basis.

Do Not:

• Aim the scanner into direct light or sunlight.

• Aim the scanner into an external object detector or other light-emitting device.

• Obstruct the scanner window with mounting hardware or other objects.

• Connect chassis of scanner and host to different ground potentials.

• Operate the scanner in excessive temperature environments.
