<Technical back ground of changing SP 2-703xxx to SP 2-710-xxx>
The engine will automatically adjust AC bias a bit depending on what environment
(temperature and humidity) the engine is detecting; the real AC bias on a media could be a
bit higher or lower than it’s set on Op panel.
These SP 2-703 to SP 2-710 are for how much this correction works. But it is turned out
the default these SP values can be too sensitive than expected in a certain environmental
condition, which can be a risk of IQ failure caused by higher or lower AC bias than the best
optimized setting and/or IQ fluctuation between morning and afternoon, for example.
These default values have been reviewed so that we can prevent this type of symptom,
but more than 500 SP settings need to be changed so you can do this action with using
debug cable and Teraterm
