(1) Check the front panel. Perform the power supply and fuse test if there is
a processor electrical malfunction. This check verifies that proper power is delivered to
machine components. Refer to figure 1-15.
(a) Plug the power cord in. The MAINS indicator should light. If it does
not, check the wall electrical outlet, or the secondary taps of the power transformer, as
appropriate. If the processor works but the indicator does not light, the light bulb is
probably burned out.
