Technical Issues Avoiding, Identifying and Resolving Adverse Electromagnetic Effects Although the system has been tested satisfactorily to Electromagnetic Comparability Standards, it is recommended that the device is not used simultaneously on a patient, with other active diagnostic devices such as blood pressure monitoring equipment. An indication of adverse electromagnetic effects from the Clinic on another electronic device would be a degradation of performance in that other device when the Clinic is operated simultaneously. If such interference is suspected, separate the two devices as much as possible, or discontinue simultaneous operation, if practical, and contact Mediwatch UK Limited. The Clinic will operate normally in the proximity of other potential interference sources, and has demonstrated immunity at a field strength of 3 V/m (per EN 60601-1-2). In the event of any external electrical disturbance causing an abnormal condition, ensure the device has shut down, switch the device back on and continue using the device as normal. No other precautions need be taken as regards exposure in reasonably foreseeable environmental conditions to magnetic fields, pressure or variations in pressure, acceleration, or thermal ignition sources. The mains plug must only be inserted in a mains socket outlet provided with a protective earth contact. It is forbidden to use extension cords. WARNING Any interruption to the protective earth conductor inside or outside the system or disconnection of the protective earth connector is likely to make the system dangerous.
