Onlv when the OQOO63 is replaced by a new type (w€eknumber > 7919) the following modifications must
be built-in:
- Short circuit resistor R413
-
Place a resistor of 220 ksr. cR16 532211130302
between pin 1 of the OOOO59 {DS1) and pin 6 of the 000063 (clock)

In these instruments, the modification as mentioned in Service note SME84 are already built'in.
For the correct modification proceed as follows:
-
Remove resistor R418 (SME84)
-
Replace capacitor C407, 15uF 1OV 5322124 14036 by a capacitor of 22nF,4822122 30103 Ceramic plate
- place a resistor of 220 kS) , CR16 5322 11 I 30302 b€tw€en pin 1 of the OO0059 (DS1) and pin 6 of the

The modification has already been built-in by the factory.
NOTE: There are several instruments with a lower serial number than DMO6 16386 and DM07 19671 in which
the modifications are alreadv built-in,
