replacement of the memory backup battery. Refer to Installing/replacing the back-up battery

Software updates require Siemens Dolphin Plus software, contact your local Siemens
representative.
It is recommended that the old software and parameters be saved to your PC before
downloading the new software.
Once installed, a master reset (P999) must be done.
The parameters can then be reloaded, either manually or downloaded from the previously saved
file. If downloading parameters via Dolphin Plus, confirm that BW500 and BW500/L is in

zero and span calibrations should be done regardless, and as soon as possible to ensure
operating accuracy.
