My new GMC-200 has a very low count rate; it's 1 CPM (10 minute average). Another GM tube detector I have reads ~15 CPM, which is what I expect from this GQ detector based on the World map. Is there an adjustment? The audible clicks are reliably counted by the software, so it's not a communication or software issue. I wonder if it may be a tube voltage issue.

Returned for repair after getting an RMA.
