DCEU Types
Two different types of DCEU exist:
one where you set the actual MU value: see section ‘DCEU With Actual Preset
MU Value’ on page 15-4.
one where you set the MU value divided by 10: see section ‘DCEU With Preset
MU Value to be Multiplied by 10’ on page 15-4
Take a close look at the DCEU in your TCR to ascertain that you have to enter either
the actual preset MU value, or the preset MU value divided by 10.
