To obtain access to the DIP switches, first remove the cover of the RRDL-3 logger, then carefully
remove the battery pack, being careful not to damage the foam seal that isolates the batteries from
the electronics. The DIP switch should be visible with the individual switch numbers being printed
on the switch itself as well as the text "OFF" on one side of the switch.
