Y The components identified by in this basic schematic diagram
have been carefully factory-selected for each set in order to satisfy
regulations regarding X-ray radiation.
Should replacement be required, replace only with the value
originally used.
Y When replacing components identified by , make the necessary
adjustments indicated. If results do not meet the specified value,
change the component identified by and repeat the adjustment
until the specified value is achieved.
