3) Positioning the Locator
Place the Locator in the slot provided for it on outside of the packaging tray, centered
above the valve, with the green arrow on the Locator pointing in the direction of
the CSF fl ow as shown by the arrow on the valve.
Figure 9
4) Positioning the Compass and Reading the Pressure
Place the Compass in the housing provided on the Locator using the guide pins:
align the lines on the Compass with the pressure values engraved on the Locator.
On the Locator read the operating pressure shown by the needle on the Compass.

Reading this initial position of the pressure setting can also be performed visually,
without using the Polaris® adjustment kit, as the valve rotor is visible through
the valve and the blister pack.
5) Positioning the Magnet and Adjusting the Pressure
Remove the Compass and insert the Magnet into the Locator.
Move the green marker on the Magnet to face the initial position of the pressure
setting (turn the Magnet in the Locator if necessary).

Hold the Locator with one hand.
Slide the Magnet, back and forth quickly along the axis of the initial position of
the pressure setting, to unlock the valve rotor, then replace it correctly in the center
of the Locator.

Turn the Magnet to the position chosen as the operating pressure for the valve which
is to be implanted.
Figure 12
Remove the Magnet vertically from the Locator to ensure eff ective re-locking of
the valve rotor in the chosen operating pressure position.
