able. Code "101" is used to clear factory diagnostic information stored in the non-volatile memory. If a code other than "101"
is entered, the command will be ignored and no actions will be taken. Various self-checking diagnostics are performed in
the background while the B30 is running, and diagnostic information is stored on the non-volatile memory from time to time
based on the self-checking result. Although the diagnostic information is cleared before the B30 is shipped from the factory,
the user may want to clear the diagnostic information for themselves under certain circumstances. For example, it may be
desirable to clear diagnostic information after replacement of hardware. Once the diagnostic information is cleared, all self-
checking variables are reset to their initial state and diagnostics will restart from scratch.
