The pre dive test keeps stoping on test 55. Why?
Test 55 is the Service Interval test. When the Discovery is delivered, it has a service interval of 104 weeks. For each week that passes, this value is counted down towards 0. When the value is 0, the unit will not pass the Pre Dive ckeck. To re-set the service interval value, you need to take your Discovery to a Poseidon Service center.
