Parameters changes from the tool are made off-line while the device is operating. The
changes are downloaded by first setting MODE_BLK = OOS then pressing the WRITE
CHANGES button. Press the READ ALL button to check the values stored in the
device. Normally operation is resumed as soon as MODE-BLK is set to AUTO.
