Troubleshooting
What should I do if…
…during charging the letter "E" appears on the Control Unit display?
An error occurred while charging. Try to reconnect the charger cable. If this
doesn’t help replace the battery or contact your NESS L300™ distributor.
… the Control Unit's display does not light up when I switch it ON?
Make sure that the Control unit's battery is charged (see the section
"Charging the batteries"). If after charging the battery, the problem
persists, replace the battery or contact your NESS L300™ distributor.
…after charging the batteries, they are still low?
Your batteries need replacing (see the section "replacing the batteries").
If the RF Stim Unit's battery needs replacing contact your NESS L300™
distributor.
… the electrodes are frayed, peeling, damaged, or falling off the
Orthosis?
• Replace electrodes (see the section "Replacing Electrodes").
• Your electrode bases may be worn, contact your NESS L300™
distributor.
