To turn CPD or DCPD on:
Select CPD or DCPD from the 2D on-screen menu to turn on CPD or DCPD.
Note: DCPD is only available for Cardiac (Card) exam type on a C15 transducer.
Note: When imaging with the iLook L25 using CPD at depths of 2.2, 2.5, and 2.8 cm, the color fill-in around
the first one (1) cm may be inversely affected by increasing the CPD gain at high gain settings. If the vessel
fails to fill with color after continually increasing the CPD gain, try slowly decreasing the gain.
