WalkAide Control Unit Troubleshooting

1. The blue light for the WalkLink shows black in WalkAnalyst program despite the cable
connections at both the laptop and the WalkAide unit.
Possibilities:
m There is a loose or damaged cable connection with either the WalkAide or WalkLink .
m T he WalkAide battery needs replacing if pressing down on the STIM
button on the unit does not show an amber light.
m The WalkLink batteries are not sufficiently charged.
The USB Bluetooth Adapter is not properly seated.
m
m Bluetooth connection: Re-establish
2. No stimulation despite the amber light when pressing the STIM button
on the WalkAide unit.
Possibilities:
m Check the electrode leads to ensure they are not broken.
m Check to make sure the electrode lead cable is firmly connected to the back of
the WalkAide.
m Replace self-adhesive electrodes or enhance contact with water or gel.
3. Intensity of the stimulation is weaker at the same setting.
Possibilities:
m WalkAide battery is weak.
m T he cuff may need to be shifted as the electrode placements are
slightly off.
m The electrodes and/or skin need to be re-wet to improve conduction.
m The cables may have been reversed (ie: Red to back)
4. Occasional sharp stimuli.
Possibilities:
The electrodes are old and need to be changed.
m
m The electrodes are not wet enough.
m The cuff is not adequately tightened causing it to shift with motion and thereby
compromising electrode/skin connection. Ensure proper positioning of cuff and
tighten the strap. Avoid tight, slim-fitting pants that can cause a pull on the cuff.
56
m Check skin under electrodes for irritation or open areas.
m Ensure total contact with skin.
5. Red light is flashing with 4 beeps every two seconds.
Possibilities:
m I ndicates a fault has occurred in the control module. Turn OFF the light blue Intensity
Knob by turning counter-clockwise to 0. Wait 5 seconds and then turn ON again to
see if the green light is flashing. If the red light remains lit, the WalkAide unit must be
returned to Innovative Neurotronics for repair or replacement.
m Contact Innovative Neurotronics at 888-88ININC (888-884-6462) for shipping
instructions.
6. Red light is flashing with an audible beep every minute.
Possibilities:
Low battery condition. Change the battery.
m
7. Red light flashing with audible 2 beeps every two seconds.
Possibilities:
I f the unit beeps two times every two seconds, you may be in heel mode. When in
m
heel mode, the Heel or Foot Sensor must be connected to the unit. Check device
parameters and make changes to 'Stimulation Mode' if necessary.
8. Red light is flashing with no audible alarm.
Possibilities:
Time clock in the WalkAide unit for usage log has stopped working.
m
Need to reset the WalkAnalyst program to Clear WalkAide Log.
m Internal time clock battery needs replacing. Contact Innovative Neurotronics.
9. The green light does not flash when the WalkAide is turned ON.
Possibilities:
m M ake sure the light blue Intensity Knob is turned to 1 or higher.
There will be a clicking noise when the knob is turned from 0 to ON.
m A new battery may be needed.
