Protective Zinc Anode Appendix L
NOTE: The zinc anode collar must be removed before you can replace the batteries for 600XLM, 600
OMS V2-1, and 6920-style sondes. A new plastic cable tie will be needed to re-secure the zinc.
WARNING: The zinc anode must not interfere with the ability to properly attach of the pressure cap to the
sonde connector – the cap MUST be threaded all the way down to prevent leaks into the connector.
Therefore, the anode must also NOT be placed over the threads of the connector.
