5.5 ADJUSTMENTS AND TESTS
The following are adjustment and tests used to check adjustments if applicable. The adjustments
have been divided into two categories – Those that are routine adjustments, and those
adjustments that should only be performed if applicable circuit parts have been replaced.
The Top Cover of the TymMachine must be removed to make the following adjustments and
tests. This exposes a potential safety hazard in the Power Supply area which is located in the
right rear corner of the unit as viewed from the front.
