23. Please put the steps below in the correct order (1-9) to demonstrate the sequence for changing the controller:

4 Pull back the white driveline cover from the original controller’s silver connector

1 Have the patient sit or lie down

5 Disconnect the driveline from the original controller (this will stop the pump)

7 Insert the red alarm adapter into the blue connector on the original controller

2 Place the new controller within easy reach

3 Connect back-up power sources to the new controller

9 Slide the white driveline cover up to cover new controller’s silver connector

6 Connect the driveline to the new controller (this will restart the pump)

8 Disconnect both power sources from the original controller

24. Put the following actions in the correct order to switch from battery operation to tethered AC power.

_3__ Connect AC power by lining up the solid white arrow on the cable connector with the white dot on the controller

_4__ Confirm that the power cable is properly locked to the controller by gently pulling on the cable near the connector

_1__ Plug the AC adapter into an electrical outlet

_2__ Disconnect the battery with the least remaining charge

25. One power source indicator will light up based on which port is providing primary power. Which statements are correct for the image below? Check all that apply

____ Power source #2 is the port providing primary power

___ The AC or DC adapter is providing power

___ Power source #1 is the port providing primary power

26. What is the procedure to clear a resolved, inactive medium priority alarm from remaining on the display screen?

___ Hold down the alarm mute button for 5 seconds to clear the alarm___ No action is needed, alarm clears itself___ Change out the controller__ Press the scroll to clear the alarm from the controller

27. Match the battery charger light to the correct battery status:

Green Battery ready for use and fully charged

Yellow Battery too cold or too hot, waiting to charge

Flashing Yellow Defective battery. Do not use

Red Battery not charging. Check connections or switch battery to another slot. If persists do

not use

Flashing Red Battery being charged, not ready for use
