I can't feel anything, is there something wrong with my device?
There are a couple of reasons why you can't feel anything. Please follow these steps to determine where the problem is:

Problem: The device does not turn on (no numbers on the display or the entire display is flashing)

• Solution 1:Change the batteries
  

• Solution 2:Check the battery connectors inside the unit. If they don't touch the battery, there is no power. To resolve this issue, move the connectors forward.
  

• Solution 3:If the timer turned the device off, you have to turn both intensity knobs to the OFF position. This will re-set the timer and the TENS unit will turn on again.
  

Problem: The device turns on, but still can't feel anything

• Solution 1:Make sure the electrodes arenotplaced more than 3" apart from each other. You can't just touch them, they have to be placed on your skin.
  

• Solution 2:1 or both of your wires are broken internally. Replace both lead wires
  

• Solution 3:Your electrodes are worn out and need to be replaced
  

Problem: The device turns on, but I can't change any settings

• Solution:The device is locked and you will see a lock symbol on the display. Push the Up and Down button at the same time until the lock symbol disappears from the display.
