Changing from Batteries to
PBU (Tethered Operation)
To change from mobile (battery) operation to tethered (PBU) operation:
1
Explain procedure to patient.
2
Insure that the PBU is plugged in and turned on and the PBU cable is attached
to the "Patient" socket on the back of the PBU (
Figure 24
).
3
Place the black and white PBU connectors within easy reach.
Note
: Periodically
inspect the connectors and connector pins to ensure they are not damaged or
dirty. Dirty or damaged connectors/connector pins/pin sockets may prevent
connection, which can affect performance.
4
Remove batteries and battery clips from the patient's holster or carrying case.
5
Unscrew the
white
connector from the 1
st
battery clip.
An alarm will sound one beep per second, the green power symbol
will flash
rapidly, and the four green battery fuel gauge lights
will flash.
6
Connect the
white
PBU cable connector by aligning the pins, pushing the con-
nectors together snugly, and then hand tightening the connectors (
Figure 25
).
The alarm will stop and both the green power symbol and battery fuel gauge
lights will stop flashing. Wait until the power symbol and battery fuel gauge lights
stop flashing and the alarm stops sounding before continuing with Step 7.
Note
:
Always connect connectors of the same color (i.e., white-to-white and black-to-
black).

WARNING !
At least 1 System Controller power lead must be connected to a power
source (batteries or PBU) at all times. Disconnecting both power leads at the same time
will cause the pump to stop. This could result in serious patient injury or death.
