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.
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.
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.

Note: fully collapse the Adjustable Height Locator
Tool (See Figure 2B).
Silicone has a low cut and tear resistance; therefore,
exercise care when placing ligatures so as not to tie
them too tightly. The use of stainless steel ligatures
on silicone rubber is not recommended.
Do not use sharp instruments when handling the
silicone valve or catheter; use shod forceps. Cuts or
abrasions from sharp instruments might rupture or
tear the silicone components.
Do not fold or bend the valve during insertion.
Folding or bending might cause rupture of the
silicone housing, needle guard dislodgement,
or occlusion of the fluid pathway.
