cannot be reset and the battery lid must be replaced before sonde deployment. Contact YSI
Technical Support for instructions.
Lightly lubricate the o-rings on the outside of the battery cover. DO NOT lubricate the orange internal o-
ring.
Return the battery lid and HAND tighten the screws with the hex driver until snug. DO NOT OVER
TIGHTEN.
CAUTION: Over-tightening the screws may cause the battery compartment to flood. Do
NOT use power tools to tighten the battery lid screws.
With the battery cover installed and secured, check the battery voltage in the sondes Status Menu. The
voltage must be 12.0 volts or higher with new cells. A voltage less then 12.0 volts could indicate that a cell
was installed upside down or that one of the cells is not at full strength.
CAUTION: Remove Batteries When Not in Use. As with any battery-powered
instrumentation, batteries should be removed before short or long-term storage. Even with
the new battery lid, batteries can leak, releasing toxic and corrosive battery acid and
damaging equipment.
INSTALLING BATTERIES IN THE 6920V2-1 AND 6920V2-2 SONDES
To install the 8 AA-size alkaline batteries into the sonde, refer to the following directions and Figures 36
and 37.

Position the bail so that it is perpendicular to the sonde and use it as
a lever to unscrew the battery cap by hand. Then slide the battery lid
up and over the bulkhead connector.
Insert batteries, paying special attention to polarity. Labeling on the
top of the sonde body describes the orientation.
