WARNING: Any maintenance work undertaken on a James Heal instrument must be done so by a trained and competent person. Where electrical work is detailed, this should only be completed by a qualified engineer. James Heal is not responsible for damage or injury arising from work carried out by any person not qualified to do so. If in doubt, please contact James Heal or your local James Heal Agent.

THE FOLLOWING PROCEDURE REQUIRES THAT THE IMPULSE IS CONNECTED TO THE ELECTRICAL SUPPLY WHILE THE COVERS ARE REMOVED AND THEREFORE SHOULD ONLY BE PERFORMED BY A COMPETENT TECHNICIAN.
