Note In the program, the 4339B is referred as \UUT".
Note If the adjustments being performed follow right after EEPROM replacement,
change switch A2SW1-1 to \CLOSE", so that the 4339B will ignore the self
test errors at power-on. (Return the switch to the \OPEN" position when the
adjustments have been completed.) Refer to Figure B-1 for the switch location.
