  The discovery potential for charged Higgs bosons has been studied including
background simulations for sqrts = 500 GeV and a luminosity of 10 fb-1
depending on the hadronic calorimeter resolution of a LC500 detector. The
hadronic decay channel H+H- --> cscs is in particular suited for this study due
to a large sensitivity dependence on the hadron calorimeter performance. For
this study a hadronic energy resolution as achieved at LEP experiments is
sufficient to reach a very good sensitivity. A calorimeter with weaker energy
resolution would reduce the sensitivity by a factor of two.
