R6 and R18 need to be upgraded to a new value, and resistor R29 should be removed. This section details field modifications authorized and recommended by Crown which should be performed This problem has only occured on 102138-8(CE1000) on affected units. Only the specific models identi- and 102140-8(CE2000) boards and earlier, (before No- fied in each case should be modified. - Page 546 Rev. D CE Series Service Manual CAUTION! The main module MUST be cleaned! To clean the board, use only a soft bristle brush and high grade IPA isopropyl alcohol. Using any- thing else can damage the components.
