Tool is fully seated in the grooves. If necessary,
maintain hold of the Adjustable Height Locator
Tool throughout the procedure to keep it firmly in
the grooves of the package.
CAUTION: Failure to maintain a fully-seated
Locator Tool above the valve mechanism
could result in an inaccurate indication of the
performance setting.
Note: Do not use the Low Profile Locator Tool for
programming the valve in the package, as it does not
contain a base that will fit into the circular grooves of
the packaging.
2. Fully seat the Indicator Tool into the Adjustable
Height Locator Tool so that the red markings are
aligned (Figure 4). You may hear a click when the tool
seats; the Indicator Tool will not rotate within the
Locator Tool when properly seated.
CAUTION: When reading the performance setting
with the Indicator Tool, make sure that the
Adjustment Tool and any other magnetic devices
are at least 36 cm (14 in.) away from the Indicator
Tool. Failure to do so can result in an inaccurate
indication of the performance setting.
3. When the number dial on the Indicator Tool stops
moving, observe the number and its position within the
window to determine the performance setting. A single
number within the window, with full purple background
and both gray side lines visible (Figure 13), indicates
the performance setting of the valve when the tools are
properly aligned. Once the valve performance setting
has been read, remove the Indicator Tool.
4. Insert the Adjustment Tool into the Adjustable
Height Locator Tool so that the arrow is pointing
to the current performance setting. With one hand
holding the "petals" of the Adjustable Height
Locator Tool, turn the Adjustment Tool with the
other hand until the arrow points to the desired
performance setting (Figure 5). The Adjustment Tool
will provide an audible click and a tactile response as
you turn to each setting.
Note: The Adjustment Tool is equipped with a
mechanical stop between Settings 1 and 8. This is to
prevent inadvertent adjustment between the extremes
of the available settings.
Note: Successful adjustment is accomplished by
starting at the valve's current setting and moving
directly to the desired setting.
5. Remove the Adjustment Tool from the Adjustable
Height Locator Tool by lifting it straight upwards a
minimum of 3 cm (1.25 in.) before moving it horizontally
away from the Adjustable Height Locator Tool in
order to avoid inadvertently changing the valve setting.
6. Repeat Steps 2 and 3 to confirm successful
adjustment of the performance setting. Always
confirm the desired performance setting of the valve.
7. If the desired performance setting is not achieved,
repeat Steps 4 through 6.
8. It is recommended to record the valve setting in the
patient's record and I.D. wallet card (available from
local Codman sales representative).
