The Activforce 2 and all included accessories are moisture-resistant, but the device itself should never be submerged in water. The device and accessories may be safely cleaned with a disinfecting wipe or a cleaning solution consisting of 70% isopropyl alcohol and water.
To remove an affixed pad accessory, grasp the soft portion of the pad and twist it to the left. To attach a different pad accessory, align the locking tabs on the accessory with the matching slots on the device, and twist it to the right. This locking mechanism is designed such that the pad accessories may be fixed at multiple angles. You may continue to rotate the pad until it is fixed in the most suitable position.

The most likely cause for failure to power on is a dead battery. See the User Guide for instruction on replacing the battery.
The battery life in your Activforce 2 device depends upon the frequency with which you are performing measurement tests. Usually, a device’s battery will last between 6 and 12 months. Activforce 2 uses a AAA battery.
The Activforce 2 device comes with a standard AAA battery, which lasts between six to twelve months, depending on usage and environmental conditions. For visual reference, see the section "Replacing the Battery" in the User Guide.
Occasionally, you may find that your strength measurements do not seem to read as accurately. If you suspect that measurements are reading slightly imprecise, go to Settings, and select Calibrate Your Device. Do not apply force before or during the calibration. This should stabilize measurement read-outs.

Although the Activforce 2 device tests a range of motion and does not calculate a starting angle, you can still measure a knee joint or elbow joint that does not have full extension. For these tests, the Activforce 2 has to be calibrated on the distal bone of the joint at a position parallel to the ground. Then once the device is calibrated, the patient then moves the proximal bone of the joint to a parallel position, and the distance that the distal end raises from the starting point is the extension measurement. For example, for someone who does not have full knee extension, the Activforce 2 should be placed at the distal tibia. Then, the patient should lift their body to allow for the shin and Activforce 2 device to be parallel to the table. Once calibrated, the patient then lowers their body to the prone position. The distance from the starting position to the ending position of the test, is the extension measurement.
