2.1.4 Grounding
Whenever coming in contact with the SymphoniePRO logger, either in the field or indoors, it is recommended to

electrostatic discharge (ESD) to the logger.
2.1.5 Installing D-Cell Batteries
Open the logger enclosure and remove the battery cover by loosening the three thumbscrews. Tip:
Write the installation date of the D-Cell on each battery.
Insert two fresh D-cell batteries, one at a time, into the battery holders with the positive terminals of
the batteries (the end with the bump) oriented towards the sides of the enclosure. When the batteries
are first inserted, the display will read:
