sensation.
The orange LED on the output socket
indicates that there is an active output.
The LED will remain on as long as the
intensity is above 0.
LOW BATTERY
The LED indicator will flash
when you need to change
the batteries. The unit will
shut down about 2 minutes after this.
OPEN CIRCUIT CUTOUT
If the TENS One is not correctly
connected to your body, the strength in
the channel which is not properly
connected will automatically reset to
zero for 3 seconds and the display will
flash. After 3 seconds, the intensity will
start ramping back up to the intensity
selected. This also happens when
changing the mode. This is to prevent
sudden changes in sensations.
