Note: Check mark is not required to indicate. The performance setting
may still be indicated as long as the device is in proximity of the valve and
accurately oriented with the valve's direction of flow.
CAUTION: Failure to move the Adjustment Tool at least 60 cm (24 in) away
from the Locator can result in challenges locating, indicating, and adjusting
the valve.
9. Once the desired performance setting has been achieved, power down
the Locator by pressing and holding the purple button on the front of
the device until the screen turns off.
Disinfect the tool kit components (see Disinfecting the CERTAS Plus Electronic
Tool Kit section).
It is recommended to record the valve setting in the patient's record and
Patient I.D. Card (available from your local sales representative).
Return both tools to their proper locations in the storage case.
Troubleshooting
If there is difficulty in indicating and/or adjusting the valve setting:
• If the display shows an indication between two settings and the Locator
is centered and oriented, remove the device from the patient and repeat
steps 1 and 2 of Section B. If the indication between settings persists and
the Locator is centered and oriented, insert the Adjustment Tool at the
desired setting and remove without rotating to a new setting.
• If there is difficulty receiving a valve indication, repeat calibration with
the Locator a minimum of 10 cm (4 in) above the valve while keeping it
aligned and parallel to the valve.
o Confirm that the Adjustment Tool is a minimum distance of 60 cm
(24 in.) away from the Locator.
o Confirm that the Locator is not tilted forward by ensuring that
the concave section of the device base is fully in contact with the
patient.
• If difficulties persist, use fluoroscopy or x-ray to determine orientation
of the valve for adjustment and/or to determine the performance setting
of the valve. A fiducial mark may be helpful for this technique. It may
be challenging to get the correct position of the Locator above the
implanted valve. Palpate to feel for the hard valve mechanism and make
sure the Locator is aligned with the valve's direction of flow.
