No.3
Symptom: Registration information of the E-RDS machine was deleted from the device
information on Web Portal, and then registered again. After that, if a communication test is
left unperformed, the device setting in the UGW becomes invalid.
Cause: When the registration information of the E-RDS machine is deleted, information
related to E-RDS is also deleted.
Therefore, when 7 days have passed without performing a communication test after
registering the E-RDS machine again, the device setting becomes invalid.
Remedy: Perform a communication test before the device setting becomes invalid.
No.4

2) Turn on the power supply of this machine and perform a communication test about 60
seconds later.
No.5
Symptom: "Unknown error" is displayed though a communication test (COM-TEST) has done
successfully.
Cause: It could be a problem at the UGW side or the network load is temporarily faulty.
Remedy: Try again after a period of time. If the same error persists, check the UGW status
with a network and UGW administrator.
No.6
Symptom: When a communication test (COM-TEST) is repeatedly executed, an error occurs.
Cause: During communication conducted after execution of a COM-TEST, another COM-
