Battery Information
Low Battery Indicator:
A battery symbol is shown on the display when the battery is
almost empty. As long as the stimulator is working normally
you can continue the treatment. When stimulation feels weaker
than usual or the stimulator turns off, it is time to replace
the new battery. If you suspect the device is not functioning
correctly due to a low battery, immediately discontinue use
until the battery has been replaced.
Check/Replace Battery:
Over time, in order to ensure the functional safety of TENS,

The Direct Supply Direct Choice Digital TENS device can be
