Once it's plugged into a grounded 110V receptacle, click each of the channel control buttons to make sure the LEDs light up on and off. 

If you don't see any LED activity at this point, make sure the ZEN20 Power Strip is on and try moving it to a different receptacle to rule out any grounding issues.

We've added a new feature that allows you two switch between LED indicator modes by clicking the CH1 button 6 times quickly. Check that the LED indicator wasn't disabled accidentally by pressing the CH1 button 6 more times to see if that activates the LED.

If the receptacle is powered and the LEDs are working fine, try performing a hard reset on the ZEN20 Power Strip if the unit is otherwise unresponsive. Just remember that this type of reset will erase all previously recorded activity along with any custom changes you had in place. 

If you notice the ZEN20 Power Strip became unresponsive after you connected a device or appliance, we also recommend checking here to verify that the connected device is compatible with the strip. Certain devices, like heavy duty equipment and chargers, will damage the ZEN20 Power Strip.

If the device is still unresponsive after trying the suggestions above, get in touch with us. We'll be happy to help.
