Online PHT
The online pressure holding test (PHT) is enabled or disabled with this button. Normally, the
PHT should be set to "Yes".
Arterial Chamber
This option is used to define whether the arterial chamber is pre-pump or post-pump. The
range of the display is different depending on the location of the chamber.
Audible Alarms
This option may be set so that audible alarms do not occur in certain situations. With "Yes"
set, audible alarms will occur in any alarm situation when either blood is sensed in the venous
blood line or the lines are off the shunt. If "No" is selected, audible alarms only occur when
blood is sensed. Note: Regardless of this setting, the machine responses, such as bypass or
blood pump and venous clamp operation are unaffected.
T and C Mode
This is for manufacturing operations only and should never be selected by the facility.
0 Arterial Limit
With this option set to yes, the upper arterial limit cannot be above 0 (with pre-pump arterial
monitoring only) when blood is sensed unless the spreading limits function is active.
Beacon (Traffic Light)
There are four possible selections for this option: Alarm, FDS08, OLC, Status:

With "Alarm" selected, the red light acts the same as the audible alarm. The yellow light
illuminates when warnings occur. The green light is illuminated when there are no
alarms or warnings.

With "FDS08" selected, the red light acts the same as the audible alarm. The yellow light
is based on a flag sent from FDS08 that indicates the machine is set outside of established
dialysis order limits. The green light illuminates when the blood volume processed has
been achieved as required by the FDS08 dialysis order.

With "OLC" selected, the red light acts the same as the audible alarm. The yellow light
is illuminated when the projected Kt/V is less than 100% of the target Kt/V (depending
on selected Service Mode option). The Green light is illuminated if there are no alarms,
and the necessary OLC parameters have been set (Volume, Target Kt/V, and OLC
enabled) and the Kt/V is projected to be at least 100% of target (depending on selected
Service Mode option).

With "Status" selected, the traffic lights act the same as the Red/Yellow/Green indicator
lights on the machine.
