VOCOM II logs critical events and errors in an internal Device Error List. See section 7.5 Status tab.
The following overview will help you to determine possible faults and their causes and to carry out troubleshooting procedures.
The function indicators help you to detect possible faults.
If you cannot rectify a fault, please contact an authorized specialist or Support.
Error codes stay in the Device Error List until cleared.
