Check to make sure that the Doppler gate covers the entire vessel. Otherwise, the real-
time volume flow measurement may not be precise.

Before you start imaging, verify that the type number or name of the transducer and the
type number or description of the puncture attachment you are using match the number
displayed on the monitor. Also make sure that the needle guide is positioned correctly. If
the numbers do not match, or if the needle guide position is not correct, the puncture line
on the monitor may not correspond to the true puncture path in the tissue. In case of any
inconsistency, stop imaging, turn off the system, and contact your local BK Medical
representative.

WARNING P-w2
Verify that the type number of the puncture guide displayed on the monitor corresponds
to the puncture guide that you are actually using. If the number is incorrect, the puncture
line on the monitor may not correspond to the true puncture path in the tissue.
