ST 3000
Copying transmitter configuration into nonvolatile memory
When setting up or configuring a ST 3000, whether you are changing one value or a configuration
database, all configuration data must be copied into the transmitter's non-volatile memory to ensure the
security of the data.
Normally, thirty seconds after a value is changed, the transmitter automatically copies it from the
transmitter's working memory into nonvolatile memory. But, if you change a value and power is
interrupted to the transmitter before the change is copied to nonvolatile memory, you will lose the data in
the working memory and it will not be saved in nonvolatile memory.
Therefore, when data is sent (downloaded) to the transmitter, be sure power to the transmitter is not
interrupted before it can be copied to nonvolatile memory.
