equipment operation in the following guide, be aware that all heaters will go off immediately after
an error indication alarm occurs if the operator takes no action. With the exception of the fuses,
there are no user-replaceable parts on the printed circuit boards. If there is a non-fuse failure on any
of the PCBs, the PCB must be replaced.
