The NESS L300 Foot Drop System is an advanced neuroprosthesis designed to improve gait in people suffering from foot drop. The NESS L300 incorporates cutting-edge technology and sophisticated design features to improve walking and quality of life.
Page 10
The wireless hand-held Control Unit monitors system status and manages system performance. Your clinician has prescribed the NESS L300 Foot Drop System to treat your foot drop. This User’s Guide describes your NESS L300 Foot Drop System and how to operate your system to achieve maximum benefits. Be sure to read this guide before using your NESS L300.
The NESS L300 should not be used where a cancerous lesion is present or suspected. • The NESS L300 should not be used on a leg where a regional disorder, such as a fracture or dislocation, could be adversely affected by motion from the stimulation.
RF Stim Unit. • Do not use the NESS L300 within three feet of short wave or microwave therapy equipment. Such equipment may produce instability in the RF Stim Unit output.
Page 13
• Do not wear the NESS L300 during x-ray examinations. • Turn off the NESS L300 when at a refueling place. Do not use the NESS L300 near flammable fuel, fumes, or chemicals. • Only your treating clinician should determine electrode placement and stimulation settings.
It should not be worn by anyone else or on any other part of the body. • Turn off the NESS L300 before putting on the FS Cuff. Do not turn on the NESS L300 until the FS Cuff is fastened in place.
FS Cuff. Skin irritation tends to occur after approximately three months of use. To promote healthy skin with long-term use of the NESS L300, it is important to follow a daily skin-care routine.
Page 16
Caution: Do not put on or operate the NESS L300 before being properly fitted and trained by a certified clinician. Caution: The Intelli-Sense Gait Sensor has not been validated for use by individuals weighing more than 136 kilograms (300 pounds).
Environmental Conditions that Affect Use Radio Frequency (RF) Communication Several components of the NESS L300 communicate via radio communication and have been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 (RF Devices) of the FCC (Federal Communications Commission) Rules.
NESS L300. The NESS L300 will likely set off the security alarm. Either ask for a “hand scan” or be prepared to remove your NESS L300 so that security can scan it.

RF Stim Unit The RF Stim Unit fits into the cradle of the L300 FS Cuff. See Figure 5-1. It responds to signals from the Control Unit and Intelli-Sense Gait Sensor to turn stimulation on/off. It has a rechargeable battery, a status light, and a stimulation light.
Intelli-Sense Gait Sensor The Intelli-Sense Gait Sensor detects when your foot is in the air and on the ground, and wirelessly signals the other NESS L300 components to move your foot accordingly. The Intelli-Sense Gait Sensor features a pressure sensor and a transmitter. The pressure sensor fits under the insole of the shoe of your weak foot, attached to a Gait Sensor pad.
Control Unit communicates wirelessly with the RF Stim Unit and Intelli-Sense Gait Sensor. It is powered by a single rechargeable AAA battery. Your NESS L300 System Kit includes a system charger set for charging the Control Unit and RF Stim Unit. It also includes a belt pouch, wrist strap, and neck strap for carrying the Control Unit.

The Control Unit has four operating modes: standby, gait, training, and clinician. Only clinicians use clinician mode. Standby Mode In standby mode, the NESS L300 System is on and waiting for commands. Stimulation is off. Gait Mode Gait mode is used when walking. In gait mode, the Gait Sensor signals the RF Stim Unit when your heel or forefoot leaves the ground, turning stimulation on.

Selecting an Operating Mode Gait Mode. To select gait mode, turn on the Control Unit, and press the mode button briefly. The Control Unit will beep and the mode button will start flashing YELLOW SLOWLY (indicating that stimulation is off). When stimulation is on, the mode button will flash YELLOW RAPIDLY.
To mute the audio alerts, lower the volume to the lowest setting. When the system is turned off, the active volume level is saved. If the active volume level is “mute”, the default volume level is automatically restored. Chapter 7 - Operating the NESS L300...
Turning On Audio Feedback During Stimulation You can choose to receive an audio alert when stimulation turns on. To turn on Audio Feedback, turn on the Control Unit and press and hold the volume button for three seconds. To turn off Audio Feedback, press the down volume adjust button or turn off the Control Unit.
Maintenance and Cleaning Charging the Batteries When a system component has a low battery, the Control Unit will beep and the component indicator light will flash YELLOW. See Table 8-1. When the RF Stim Unit battery is low, the RF Stim Unit status light will also flash YELLOW.
Page 48
To charge the batteries in the Control Unit and RF Stim Unit: 1. Open and assemble the System Charger Set. The System Charger set comes with four interchangeable blades for U.S. and international outlets. Select the appropriate blade that fits the chosen power outlet and slide the blade onto the end of the charger.
Page 49
Caution: Do not use the RF Stim Unit or Control Unit while charging. Caution: Use only the charger included in your NESS L300 System Kit. Use of any other charger could damage the system. 3. Connect the system charger set to the Control Unit and RF Stim Unit.
Page 50
Note: It is possible to charge the Control Unit and RF Stim Unit separately, but Bioness recommends that the Control Unit and RF Stim Unit be charged at the same time. 6. The charging process will continue until a horizontal GREEN line appears in the Control Unit digital display and the RF Stim Unit status light is solid GREEN.
Replacing the Batteries RF Stim Unit Battery The RF Stim Unit rechargeable battery should be replaced approximately every two years by a Bioness certified technician. Intelli-Sense Gait Sensor Battery The battery in the Intelli-Sense Gait Sensor is not rechargeable. It should be replaced approximately every six months.
2. Slide the cover out. 3. Note the “+” orientation of the old battery. 4. Remove the old battery and properly dispose of it according to your local environmental regulations. 5. Insert the new battery. The “+” should face outward. 6.

Note: Store the L300 Cloth Electrodes, when not in use in the Cloth Electrode Mesh Bag or in a location where they can air dry. Figure 8-8: Replacing the L300 Cloth Electrodes. (Regular L300 Cloth Electrodes and Regular L300 FS Cuff shown.) Chapter 8 - Maintenance and Cleaning...
Caution: Use only L300 hydrogel electrodes supplied by Bioness. Caution: Do not use your NESS L300 System without electrodes. To replace the L300 Hydrogel Electrodes: (See Figure 8-9) 1. Turn off the Control Unit and remove the L300 FS Cuff..
Page 59
Note: Save the covers. Always reapply the covers between uses. When reapplying the covers, make sure the Bioness logo faces up. Note: If the electrode gel becomes dry, rehydrate it with one to two drops of water. Figure 8-9: Replacing the L300 Hydrogel Electrodes. (Regular L300 Hydrogel Electrodes and Regular L300 FS Cuff shown.)
Replacing the Electrode Bases You will need to replace the electrode bases after one year of use. Contact Bioness to purchase replacement electrode bases. For Regular L300 FS Cuff users, if you are switching from hydrogel to cloth electrodes, or from cloth electrodes to hydrogel electrodes, you will need to be seen by a qualified clinician for a first fitting.
Removing the RF Stim Unit The only time you should remove the RF Stim Unit is to clean the FS Cuff or replace the RF Stim Unit. To remove the RF Stim Unit: 1. Turn off the Control Unit. 2. Pull the top of the RF Stim Unit away from the cradle. See Figure 8-11. If the fit is too tight, open the flexible cover over the charging port for a better grasp.
Cleaning Your NESS L300 Components All NESS L300 components may be cleaned by carefully wiping them with a damp cloth. The electrical components are not waterproof. Do not immerse them in water. The L300 FS Cuff is the only component that can be immersed in water to clean.

NOTE 1: At 80 MHz and 800 MHz, the higher frequency range applies. NOTE 2: These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from structures, objects, and people. For transmitters rated at a maximum output power not listed above, the recommended separation distance d in meters (m) can be determined using the equation applicable to the frequency of the transmitter, where P is the maximum output power rating of the transmitter in watts (W) according to the transmitter manufacturer.
