Reset to Defaults
It may be necessary to reset the H-3553 settings back to factory defaults. Using the RS-232 menu, press the ‘P’
key to enter the “ Advanced Options” menu and then press the ‘D’ key to “ Reset Defaults”.
To reset to defaults using the SDI-12 interface, send the “aXSDEF!” SDI-12 extended command. The response
should be “a0041” which means that it will take 4 seconds to reset to defaults. Note in Table 4-4, the ‘a’ is the
current address of the H-3553.
