Suggestions for Priming the Handpieces
Do not lay the handpiece and the empty test chamber down and have the system fill the test
chamber. When you lay down the handpiece, this allows air to collect in the test chamber
and can produce an error. Point the tip of the handpiece up to reduce the amount of bubbles.
1. Use Continuous Irrigation to fill the tubing with fluid. Remember to hold the ends of the
tubing over a container to catch any fluid.
2. Use the Continuous Irrigation or Cup Fill feature to fill the test chamber with fluid and to
eliminate all air. Remember to remove the test chamber from the handpiece, if needed,
before you start the cup fill process.
3. Place the test chamber over the handpiece tip and the sleeve hub.
4. Attach the tubing to the handpiece, if needed.
5. Tap the Prime/Tune button, this starts the prime and tune sequences.

To perform a prime only, tap the Prime button.

To perform a tune only, tap the Tune button.
6. Ensure low ceilings, light fixtures, or equipment do not block the movement of the IV
pole. Do not manually adjust the IV pole height with the remote control or rocker switch
during Prime/Tune sequences.
7. Watch the fluid fill the drip chamber. The fluid moves toward the handpiece and fills the
test chamber.
8. The display screen indicates the progress of the prime and tune process.
9. As the tubing lines fill, the system software performs functional checks. The checks
include:

Monitoring for the presence of irrigation flow (bottle height)

Leaks (via vacuum rise checks)
10. When you attach the phaco handpiece and tap Prime/Tune or Tune , the system
automatically includes a handpiece tuning test concurrently with the prime cycle.

At the end of the priming sequence, the system makes an audible sound to indicate
that Prime process is complete.

At the end of the phaco tuning test, the system makes an audible alert sound to
indicate that Tune process is complete.
11. To discontinue prime or tune during the process, tap Cancel .
12. When prime and tune are complete, the system automatically proceeds to the
preprogrammed submode or Phaco 1 operating mode. It is important that you verify the
Irrigation and Aspiration balance prior to operating.
