It is a very simple process. All it takes is a few clicks and I will show you the steps below. I will use the word GENERATOR when I am talking about the surgically placed unit in my chest that delivers the therapy to my brain.
This is my DBS programmer. It has a small white button on the bottom right side that turns the programmer on and off. There is also a larger white button at the top left that is used to turn the generator on or off. I will be using the ORANGE button with the check mark on it for this tutorial.
Place the programmer, or the attached antennae on top of your generator and press the orange button. When I do it, this is what my screen looks like.
Now, see the box outline around the center line where it says OK? The OK means that my generator battery is OK. But what if I want to know how much life is left? I use the arrow buttons on the bottom of the programmer and push the right arrow once. This is what my screen looks like after.
It says OK and 2.89 V.
When my generator was brand new, my reading was 3.20 V. A year ago, it was 2.98 V. In January, it was 2.91 V. When it gets down to 2.61 V, I will get an ERI message warning me it's time to contact my doctor to schedule surgery to replace the generator.
Sometimes the outline is around the top line.
This line tells me the generator is ON. If I use the arrows and move it to the right, it will display the programmer batteries. The AAA batteries in the patient programmer.
It says Low and 25%. So I need to put new AAA batteries in my programmer. PS I use rechargeable ones.
You can use the up & down arrows at the bottom of the programmer to move the outline box on the screen.
I check my generator battery once a month. That way, I can see how quickly it is discharging. In my case, I should be good for at least another year.
An easy way to remember is....generator life is always displayed as V and programmer batteries as percentages.
PS This tutorial is for the Medtronic DBS non-rechargeable generator.
