Changing Your Battery
Device: 523/723 (Revel), 522/722, Guardian, 515/715, 512/712
To insert a battery, you will need your pump, a new AAA alkaline battery, and a thick coin (nickel or quarter). Do not use a rechargeable or carbon zinc battery in your pump.
Make sure all the following apply:
Clear (ESC, ACT) any alarms and/or alerts before removing and replacing the battery.
Make sure the pump is at the HOME (idle) screen when you remove the battery.
Do NOT remove the battery during a bolus or Fill Cannula delivery.
Place the edge of the coin in the slot of the battery cap. Turn the cap to the left (counter-clockwise) until it comes off.
Remove the old battery and dispose of it per the disposable requirements of your state or country.
Place the new battery in the pump with the negative end [(-) symbol] going in first. Check the label on the back of the pump to make sure the battery is inserted correctly.
Note
Do not use batteries that have been in cold storage, such as in the refrigerator or in your car during winter in cold climates.
Replace the cap. Use the coin to turn the cap to the right (clockwise) and tighten until the slot is horizontal.
Important
Be careful not to overtighten the battery cap!
The pump should power-up. It will count up to 7 and then display the HOME screen. If the HOME screen displays, your battery is good, and it is inserted correctly. If the HOME screen does not display, follow the steps below:
You may have inserted a battery that has been used for a short time.
You can clear this message and continue, but the battery may not last as long as a new battery.
Clear the alert by pressing ESC, and then ACT.
The HOME screen should appear.
Check to make sure the time and date are correct. If more than 5 minutes have passed since you removed the battery, you will be prompted to check.
Press ESC to view the STATUS screen, making sure no alarms are active. If an alarm is active, follow the instructions on the screen.
