before continuing with the Adjustment Procedure.
See the "Cabinet" remove and replace instructions
located in the "Maintenance" section of the manual.
c. CHECK—Display amplitude is 4.2 divisions or
greater as the generator output frequency is increased up
to the value shown in Table 5-6 for the corresponding
