How do I know the BodyGem device calibrated correctly?
The BodyGem device is designed to self-calibrate. If calibration is not completed, error message Er05 will appear in the LCD and the lighted button on top of the BodyGem device will turn red. This message indicates the BodyGem device has detected a flow of air during the calibration and was unable to complete the calibration process. If you continue to experience Er05 messages, contact Microlife at 1-800-968-1378.
