thanks for the help marzac2....I do already have that feature installed (which btw is very cool feature ) so that must have been an earlier firmware update as I am at firmware v1.7...after reading more i see that there up to about v2.4 but doesnt really explain the improvements or advantages of the later updates....I'm not exactly comfortable doing the later upgrades cause i dont want to ruin my charger so i may just leave it at v1.7 for the time being....thank you very much for the help
