    Classic owner’s manual (continued) Sealed or Vented The Classic has the ability to be sealed for protection from salt air or dust. It comes from the factory Vented. If you live in a dusty or salt air environment you may wish to seal the Classic. Sealing the Classic does not make the unit water resistant.

  • Page 15: Follow-Me" Charging Coordination

    Classic owner’s manual (continued) “Follow-ME” Charging coordination Follow-Me will allow Classics to share charge stages, as well as Battery temperature info and Ground fault coordination. Follow-Me also allows you to program a single Classic for Equalize charging and it will instruct all the others to Equalize as well. You do need to set the Equalize parameters in each Classic. For the Battery Temp sensor you will need one BTS only and it can be on any of the Classics.
  • Page 16 Classic owner’s manual (continued) Addressing the Classics You can assign unique addresses to each networked Classic. This is not necessary for Follow Me to work but it is necessary if you want to view multiple Classics from a single MNGP. To address a Classic simply use the MNGP that is plugged into that Classic, or plug the MNGP into that classic and hold the Left arrow button down and tap the up or down button.
