Appendix K — 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 bar code symbol.
• Check the bar code symbol for readability by doing a decode rate test. If there is
any question about the symbol'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.
