7. Conclusions Satisfactory results of RLS components repairs
Low cost (150 instead 1000 CHF when additional production made),
Good efficiency,
But: tests in 904 needed: eye diagram, configurations, data transfer, etc
The end of June – we should have enough spares for all RLS components and RLS spare components problem solved.
