What should I do if…

…I hear a beep, the RF Stim Unit's indicator on the Control Unit

turns

red and the letter "E" appears

on the

intensity display?

This is a symptom of Bad Electrode Contact. To resolve this follow

these steps:

1. Turn OFF the Control Unit.

2. Remove the Orthosis from your leg.

• Make sure the electrode liner is removed and there is no

interference to the contact between the electrodes and the skin.

• Make sure that the electrodes are installed properly. The electrodes

may be missing or damaged. If this is the case then install new

electrodes according to the section "Replacing Electrodes".

3. Put the Orthosis back on your leg, turn the Control Unit ON, and

press the Gait mode button.

If the problem persists then:

4. Check that the RF Stim Unit is installed properly (see the section

"Removing and Installing the RF Stim Unit").

If the problem persists then contact your NESS L300™ distributor.
