Operational Tips
Appendix L — Operational Tips
Do:
• Check inputs (symbol speed, length, height, etc.) to ensure the desired number of
decodes per symbol.
• For optimum decodes, mount scanner so that your symbols pass through the center of
the depth-of-field (minimum/maximum range). You find the center by moving your symbol
in and out during a read rate test.
• Avoid excessive tilt, pitch, and skew of the symbol.
• Check the symbol for readability by doing a decode rate test. If there is any question
about the symbol's readability, contact your Microscan sales representative.
• After changing any parameter that might affect decode rate, repeat decode rate test.
• Clean the scanner window with a clean, dry cotton swab 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.
