Hi Bob
thanks for taking the time to do my homework for me.
The M200 is actually in Auckland,I haven't had it sent to me yet so I may need to divert to one of the North Island Techs.
New Zealand is only a small country but the disconnection between North & South makes for expensive courier fees.
We have some very capable electronics people in the greater Christchurch area but unsure of anyone with specific knowledge.
The manuals on this site offer me confidence we should be able to get to the bottom of any issues.
kind regards
