When it is suspected that your MAS is not operating correctly, a
few simple checks can be made before dismantling for repair:
1. Make sure there are no leaks in the line.
2. Check that all cables are plugged in and are in good condition.
3. Check that the power supply is in the correct range.
4. Double-check connector pinouts.
This guide is provided to help locate the section of the MAS at
fault. It is not intended to be an all-inclusive repair manual. In the
case of most repairs, your MAS should be returned to the factory
for service.
