- Do not use the device simultaneously with other electronic equipment to avoid elec-
tromagnetic interference with the operation of the device.
- Do not use the device near, on, or under other electronic equipment to avoid electro-
magnetic interference with the operation of the device.
- Do not use the device in the same room with other equipment such as life-support
equipment, other equipment that has major affects on the life of the patient and
results of treatment, or other measurement or treatment equipment that involves
small electric current.
- Do not use the device simultaneously with portable and mobile radio frequency com-
munication systems because it may have an adverse effect on operation of the
