However, the cautery electrodes must not contact the implant and should be kept more than ~ 2 in. (1 cm) from the extracochlear electrodes. • Diathermy: Do not use therapeutic or medical diathermy (thermopenetration) using electromagnetic radiation (magnetic induction coils or microwave).
N02210F ISS4 DO2.qxd 24/4/02 1:13 PM W A R N I N G S Page 73 A N D P R E C A U T I O N S Magnetic Resonance Imaging (MRI) Magnetic Resonance Imaging (MRI) is contraindicated except under the circumstances described below. Do not allow patients with a cochlear implant to be in the room where an MRI scanner is located except under the following special circumstances. The Nucleus 24 cochlear implant has a removable magnet and specific design characteristics to enable it to withstand MRI up to 1.

Long-term Effects of Electrical Stimulation Most patients can benefit from electrical stimulation levels that are considered safe, based on animal experimental data. For some patients, the levels needed to produce the loudest sounds exceed these levels.

The speech processor must not be opened by anyone other than Cochlear’s qualified service personnel or the warranty will be invalidated. Each speech processor is programmed specifically for each individual. Do not wear another person’s speech processor or lend yours to another user. Using another person’s speech processor may result in uncomfortably loud or distorted sounds.
