Troubleshooting - Zynex Medical InWave User Manual

Problem
Unit stays on even
after treatment ends.
Cannot increase
stimulation level from
its current setting.
Display shows "Check
Connections".

Troubleshooting

Hold Off button down for two seconds to shut unit off.
Otherwise unit will shut off automatically after five
minutes of no stimulation. Alternatively you can start
a new treatment session after the last one ends.
Press and release Unlock button to unlock this safety
feature. Then increase stimulation to the desired level/
intensity. Intensity level is locked after twenty
seconds of inactivity.
The probe is not properly connected to the device.
Check to see that the probe connector is properly and
completely inserted into the device. Turn the device
off and disconnect and reconnect the probe if
necessary to establish a better electrical contact. If the
"Check Connections" indicator persists the probe may
be faulty. Contact Zynex technical support (Page 4) for
further assistance.
