Troubleshooting
• Amplifier Unit error
Check the status of the indicator LEDs after transmission of the command.
After taking appropriate corrective action, send the write command again and check again.
RUN
• If the response code is 1 :
There is a host device communications error.
Check the status of the indicator LEDs and the response code of the response after transmission of the
command.
After taking appropriate corrective action, send the write command again and check again.

• If the response code is 7 :
There is a communications error in communication between the CIDRW Head and ID Tag.
Check the status of the indicator LEDs and the response code of the response after transmission of the
command.
After taking appropriate corrective action, send the write command again and check again.

70 • Background noise levels of the CIDRW Head (Check the surroundings with the environmental noise level measurement
• Distance to another CIDRW Head
• Influence of background noise (Change installation position)
If the error cannot be resolved after checking, the Amplifier Unit may be damaged.
71 • ID Tag overwrite life (Replace the ID Tag)
• Environment of use of the ID Tags (ID Tag breakage due to use in unanticipated ways)
72 • Connection to the CIDRW Head
• Distance between the ID Tag and CIDRW Head
• CIDRW Head background noise levels (Check the surroundings with the environmental noise level measurement function)
• Distance to another CIDRW Head
7B • Distance between the ID Tag and CIDRW Head
• Background noise levels of the CIDRW Head (Check the surroundings with the environmental noise level measurement
• Distance to another CIDRW Head
• Influence of background noise (Change installation position)
7E • Type/specifications of the ID Tags used
• Settings of the ID Tags used (The ID Tag lock function is used.*)
7F
• Environment of use of the ID Tags (ID Tag breakage due to use in unanticipated ways)
* The ID Tag has a lock function, but the amplifier unit has no function for locking an ID Tag.
