Device specifications
The external neurostimulator (Figure 1) is a programmable device that delivers stimulation
through one or more leads (delivered through one lead at a time). The stimulation settings are
stored in programs. A program is a specific combination of pulse width, rate, and amplitude
settings acting on a specific electrode combination.

Instructions for use
The external neurostimulator is used to evaluate lead placement and stimulation settings.
w
Warning: This device was designed for single patient use only. Do not reuse , reprocess,
or resterilize this product. Reuse, reprocessing, or resterilization may compromise the
structural integr ity of the device and/or create a risk of cont amination of the device, which
could result in patient injury, illness, or death.
#
Caution: The device is not certified for use in the presence of a flammable anesthetic
mixture with air or with oxygen or nitrous oxide. The consequences of using the device
near flammable atmospheres are unknown.
#
Caution: Do not modify this equipment. Modification of this equipment can result in
damage to the device, causing the device to malfunction or become unusable.
#
Caution: Do not use the device in the proximity of equipment that generates
electromagnetic interference (EMI). EMI may cause a disruption in device function.
Examples of common medical sources of EMI are magnetic resonance imaging (MRI)
and lithotripsy. Powerful computer monitors, cell phones, x-ray equipment, and other
monitoring equipment may also generate EMI.
Note: Turn off and dispose of the external neurostimulator after defibrillation. For more
information on the effects of defibrillation on the neurostimulator, refer to the Information for
Prescribers Booklet.
Pairing the external neurostimulator to the controller
For instructions on pairing the external neurostimulator to the controller, refer to the
appropriate controller programming guide.
Using the external neurostimulator during test stimulation
When programming during test stimulation, keep the controller within 3 meters (10 feet) of the
external neurostimulator. The external neurostimulator does not attach to the controller.
Using the ENS button
The ENS button is used to place the external neurostimulator into discovery mode to establish
communication with a controller. It can also be used when you need to immediately turn off
the external neurostimulator. You must use the controller to turn on the external
neurostimulator. The ENS button is not an on/off control.
Press and hold the ENS button for at least three seconds to turn off the external
neurostimulator or to place the external neurostimulator into discovery mode.
Understanding the LED on the external neurostimulator
Once batteries are inserted into the external neurostimulator, the external neurostimulator
turns on, and the light-emitting diode (LED) shines continuously for a few seconds. When the
LED begins to blink, the external neurostimulator has completed initiation, has entered
discovery mode, and can be paired to a controller.

Notes:
The external neurostimulator will remain in discovery mode for 90 seconds, or until it
▪
successfully pairs with a controller, at which point the LED will stop blinking and turn
off.
The LED blinks whenever the external neurostimulator is in discovery mode, or when it
▪
receives data from a controller.
Refer to the appropriate programming guide for more information on using the
▪
controller.

Replacing the external neurostimulator batteries
For instructions on checking the external neurostimulator batteries using the controller, refer
to the appropriate controller programming guide.
#
Caution: Do not leave depleted batteries in the external neurostimulator. The batteries
may corrode and cause damage to the electronic components.
#
Caution: If the device will not be used for several weeks, remove the batteries from the
device. A battery left in the device may corrode, causing damage to the electronic
components.
Notes:
Before inserting batteries, check for signs of battery leakage. If any residue is present,
▪
do not use.
Stimulation settings may not reflect programming changes that were made prior to
▪
replacing the batteries.
1. If the external neurostimulator is on, use the programmer to turn the external
neurostimulator off.
2. If the connector cable is attached to the external neurostimulator, disconnect the
cable.
3. If the external neurostimulator is in the external neurostimulator belt or boot, remove the
external neurostimulator from the belt or boot.
4. Press down lightly on the battery compartment cover, slide the cover outward, then
remove the cover (Figure 2).

Using the external neurostimulator boot
The external neurosti mulator boot is a single-use accessory. The external neurostimulator boot
is attached to an adhesive pad, which can be used to adhere the external neurostimulator to
the patient's body.
Note: Schedule a visit during the test stimulation phase to replace the initial boot with a new
boot.
1. Ensure that no cable is attached to the external neurostimulator. The external
neurostimulator can not be inserted into the boot with a cable attached.
2. Insert the external neurostimulator into the boot (Figure 5).
