[1] Vertical grooves. Used to ensure the correct positioning
of the Compass and the Magnet inside the Locator.
[2] Reading area. Shows the valve model on the left and
each of the five pressure levels associated with this refer-
ence.
[3] Rotating ring. Used to select the reading area corre-
sponding to the valve model to be adjusted.
See Table 1 to determine the valve model and the pressure
range to be displayed.
[4] Arrow showing the direction of the CSF flow. Used to po-
sition the Locator correctly in relation to the valve.
[5] Central cut-out area. Used to center and position the Lo-
cator accurately and as closely as possible to the valve.

6.2. Compass

The Compass fits into the Locator and enables direct reading
of pressure values.
The needle indicates the exact orientation of the valve rotor.
When used in conjunction with the Locator, the Compass en-
ables the valve pressure to be read.

[6] Central target. Used to refine the position of the Compass
above the valve.
[7] Needle. Indicates the orientation of the valve rotor.
[8] Lateral lugs. Used to vertically guide the Compass into
the internal grooves of the Locator.
[9] Compass needle shaft. To be centered in the target.

6.3. Magnet

CAUTION
Keep the Magnet away from electromedical devices for
care or diagnosis (i.e. pacemaker, patient monitor, elec-
tronic measuring devices, imaging devices, etc.). The
magnetic field of the Magnet could provoke electro-
magnetic disturbance and altere their operation.
CAUTION
Do not store or handle the Magnet near any device like-
ly to be altered by a powerful magnetic field.
CAUTION
Do not move the Magnet close to a powerful magnetic
field (e.g. MRI). It could become a dangerous projectile
or its performance could be affected.
CAUTION
Handle the Magnet with care near metal objects (e.g.
hospital furniture). They could become violently attrac-
ted.
The Magnet is made up of a specific assembly of magnets
designed to enable the rotor to be unlocked and the pres-
sure of the Polaris valve to be adjusted.
To operate correctly, the Magnet must be properly centered
above the valve and aligned with the valve rotor.
The Magnet fits into the Locator.
It makes it possible to adjust the pressure by rotating the
Magnet.
[10] Blue mark. Used to align the Magnet with the valve rotor
using the indication given by the Compass.
[11] Lateral lugs. Used to vertically guide the Magnet into the
internal grooves of the Locator.
[12] Handle.
The Magnet handle can be off-centered towards the front or
the back to be able to make backwards and forwards move-
ments.
