7. Maintaining the recorder
To keep your Welch Allyn CardioPerfect recorder in good working condition, please observe
the following:
Remove the battery when you do not use the recorder for a longer period of time.
Do not expose the recorder to temperatures lower than –15° C or higher than 45° C, at
a maximum non-condensing humidity of 95%.
Clean the cables regularly.
Replace the battery of the recorder when the power indicator light is red.
7.1 Clean the cables
When you use electrodes that need electrode gel, make sure that the cables and the non-
disposable electrodes are cleaned regularly. Otherwise, the gel may build up on the wires.
Use a moist cloth to clean the cables and the electrodes.
7.2 Replace or charge the battery of the recorder
The Welch Allyn CardioPerfect Portable recorders are powered by a 9V alkaline battery. The
Welch Allyn CardioPerfect Pro recorder has a rechargeable battery. You need to replace or
charge the battery when the power indicator light becomes red instead of green. Do not use the
recorder when the power indicator led is red.
After you replaced or recharged batteries, let the Pocket ECG software run in Monitor mode for
a few seconds. This verifies that the recorder functions properly and the cable is undamaged.
To replace the battery of Welch Allyn CardioPerfect portable recorders:
The battery compartment is located at the bottom of the unit.
1. Remove the battery lid with a pair of tweezers.
