dialyzer in the Final Dialysate (post proportioning and the reaction of the acid
and bicarbonate concentrates). Selecting this button and using the  or  (up
or down) keys on the Keyboard, the operator can set the base sodium content of
the dialysate in milliequivalents per liter (mEq/L). The values of some of the
other constituents will change as this parameter is adjusted (see Table 12 on
page 66 for more information).
Bicarbonate—This is the prescribed bicarbonate that will be delivered to the
dialyzer in the Final Dialysate (post proportioning and the reaction of the acid
and bicarbonate concentrates). Selecting this button and using the  or  (up
or down) keys on the Keyboard, changes the bicarbonate level in
milliequivalents per liter (mEq/L). The values of some of the other constituents
will change as this parameter is adjusted (see Table 13 on page 67 for more
information).
Dialysate Flow On/Off—Selecting and confirming this toggle-button will turn off
dialysate flow. The value displayed in the Dialysate Flow button on the "Home"
screen will flash when dialysate flow is turned off with this toggle-button. Select
and confirm this button again to resume dialysate flow at the previously set rate
(software version 2.34 or later).
Acid/Bicarbonate Alert—Selecting this button opens a subscreen with options
to notify the user when there is only 20 percent concentrate remaining in either
supply jug. See "Setting the Acid/Bicarbonate Alert" on page 71.
Alarm Position—Selecting this button and using the  or  (up or down) keys
on the Keyboard, the operator can shift the conductivity alarm window, up or
down in 0.1 mS/cm increments. The alarm window can be shifted 0.5 mS/cm
above or below the TCD of the selected concentrate type within the maximum
upper limit of 16.0 mS/cm, and the minimum lower limit of 12.5 mS/cm. For more
information, see "Conductivity Limits" on page 72.
Alarm Width—Selecting this button and using the  or  (up or down) keys on
the Keyboard, the operator can change the width of the conductivity alarm
window from 0.6 to 1.0 mS/cm width. For more information, see "Conductivity
Limits" on page 72.
SVS Profile—This button, which also appears in the "Home" screen, opens the
"Sodium Variation System (SVS) Profile" subscreen. For more information, see
"Sodium Variation System" on page 83. This button is colored green when an
SVS profile is running (software version 2.34 or later).
If the SVS option is set to 'No' in Service Mode, this button will not be displayed.
