Theft detection systems may also produce EMI. While some theft detection systems
are obvious and are located at store exits, others may be concealed within the store. If
you are in a store or other environment and suspect EMI is affecting your device, turn
OFF the Senza system and move out of the area. Once you are out of the area, check
whether therapy is ON or OFF. You may have to recharge the device. If you have
specific questions about EMI sources, talk to your doctor.
Strong electromagnetic fields arising from closeness to electrical equipment such as
mobile phones, satellite phones and radio systems may interfere with the radio
communication between the Remote Control and IPG. As described in the
“Troubleshooting” section of this manual, communication failure is indicated by three
beeps. Communication can be restored by moving away from the interfering electrical
equipment and retrying the operation.
Electrostatic Discharge (ESD) is a common source of electromagnetic interference that
can occur when a person or object accumulates a static charge. ESD is made worse by
low humidity and synthetic materials.
• If the battery terminals of the Trial Stimulator are exposed to ESD, the device
may reset and stop stimulation. Stimulation can be restarted by following the
instructions in the “How to Turn ON Stimulation” section of this manual. To
avoid unintentionally stopping stimulation, do not open the battery
compartment while stimulation is ongoing.
• ESD may cause the Charger to stop charging the IPG. If this happens, charging
can be resumed by repeating the steps in the “How to Charge the IPG” section
of this manual. ESD events can be minimized by keeping the charger in the
Charger Holster while recharging the IPG.
WARNINGS ABOUT OTHER MEDICAL
TREATMENTS
Always tell your doctors, nurses, and other clinicians (including dentists, physical
therapists, occupational therapists, and others) that you have the Senza Spinal Cord
Stimulation system implanted in your body. There are some procedures that are not
recommended for people with the Senza system, and there are other procedures
which may be possible for you only with certain precautions. If you ever need any of
these treatments, be sure to discuss them with your pain doctor as well as with the
clinical team doing the procedure.
Procedures that are not recommended for you with an implanted SCS system include:
• Diathermy
• Computed tomography (CT scans)
