Operating Control
Conditions
Pulsed Doppler A
Note 1:
Only one operating condition per index.
Note 2:
Data should be entered for "at surface" and "below surface" both in the columns related to TIS and TIB.
Note 3:
Information on MI and TI need not be provided regarded using TIC for an TRANSDUCER ASSEMBLY not intended for
transcranial or neonatal cephalic uses.
Note 4
If the requirements of 201.12.4.2a are met, it is not required to enter any data in the columns related to TIS, TIB or TIC
Note 5
If the requirements of 201.12.4.2b are met, it is not required to enter any data in the columns related to MI.
Note 6
Unshaded cells should have a numerical value. The equipment setting related to the index has to be entered in the operat-
ing control section.
Note 7
The Depths z
