1. The default setting for Service Type is “Custom,” which enables you to

enter a Service Code that is not available from the Service Type pulldown
menu. When you select a Service Type other than “Custom” from the
pulldown menu, an appropriate Hex. value is automatically assigned to
the Service Code box which grays out (inaccessible).
