In Primus 701A the gain
can be adjusted also in Wx mode. It can also easily be reset to calculated( fixed gain) to get the appropriate WX readings with correct colors. When used in Wx Alert mode the gain is fixed and cannot be changed.
If the above apply to S92 due to implementation etc, I do not know.
