This program does not back up programs or data. Be sure to perform IPL after performing CLEAR
and/or WRITE READ Test.
The data contained in the area used to perform CLEAR or WRITE Test is not protected.
In order to perform CLEAR or WRITE/READ Test, the program and data are copied as backup
temporarily in an available area of RAM.
Do not turn OFF the power during the test. Doing so may destroy the program and the proper
operation cannot be guaranteed. Should this occur, all operations, starting IPL, must be
performed.
