Replacing
the AAA alkaline batteries
When the batteries are approximately 75% empty the battery symbol will appear on the Qardio app
blood pressure measurement screen. Although the QardioArm will continue to measure reliably, you
should obtain replacement batteries.
If the empty battery symbol appears on the Qardio app, your QardioArm batteries are depleted and it’s
time to replace them. You cannot take any further measurements and must replace the batteries. You
should replace all four AAA alkaline batteries at the same time. Use 4 new, long-life 1.5V, size AAA
batteries. Do not use batteries beyond their expiration date.
To replace batteries:
1.
Release the batteries compartment hatch by pressing the button under the
cuff as shown in the drawing.
2.
Replace all four AAA alkaline cells with new ones, ensuring that the polarities
are correctly aligned: the + (positive) and – (negative) polarities should match the
polarities indicated on the AAA alkaline batteries compartment.
3.
Put the batteries compartment hatch back in place, pushing until it clicks in
place.
4.
You will see a green light shining through the batteries compartment hatch.
Resetting the pairing
In order to reset the pairing,
unwrap the cuff from around the QardioArm to switch
on the device and use a paper clip to press the button on the pinhole on the battery
compartment hatch. You should see a green light shining through.
If necessary, go in the Settings of your phone or tablet, select the QardioArm and
select forget device.
Accuracy testing and maintenance
QardioArm comprises sensitive components and must be treated with caution. Observe the storage and
operating conditions described in the “ Technical Specifications” section.
If you can’t fix the problems using the troubleshooting instructions, please contact Qardio customer
service on www.getqardio.com
We recommend the QardioArm is tested for accuracy every 2 years or after mechanical impact (e.g.
being dropped). Please contact Qardio customer service on www.getqardio.com to arrange the test.
