The problem that is identified below does not have a known permanent solution. Until a permanent solution is known, use the solution that is identified below.Problem
There have been reported incidences of lost registration and configuration data from the field. Engineering has reproduced the failure mode in the lab. When the data loss occurs, Product Link may appear to lose registration and configuration parameters.Solution
When loss of registration and configuration parameters occurs, reconfigure a new registration message and submit the new registration message without replacing the ECM. Once this process has been completed, Product Link is expected to function normally.If needed, refer to the "Connecting a Computer to the Product Link System" or the "Configure and Register Product Link PL121SR Radio and PL300 ECM" sections that are found in Special Instruction, REHS2365.
