Appendix J — Operational Tips
Do:
• Check inputs (symbol speed, length, height, etc.) to ensure the desired number of
decodes per symbol.
• Connect reader to host before connecting power to the reader; disconnect power
before disconnecting the host from the reader.
• For optimum decodes, mount reader 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 ques-
tion 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 reader window with a clean, dry Q-tip or cotton cloth on a regular basis.
Do Not:
• Aim the reader into direct light or sunlight.
• Aim the reader into an external object detector or other light-emitting device.
• Obstruct the reader window with mounting hardware or other objects.
• Connect chassis of reader and host to different ground potentials.
• Operate the reader in excessive temperature environments.
