GFCI Test
Before using the equipment, press the GFCI button to check if it can return to the original posi-
tion. If not, please do not plug the equipment into the electrical circuit and ask a professional
electrical engineer for help. If the button works, please press the button on the socket.
The transmitter (A) has to be connected to the socket. When the GFCI button is pressed for at
least 8 seconds, the LEDs (1) will be turned off after releasing the GFCI button. If the circuit did
not reset the GFCI button, either the wiring or the GFCI button are not correct.
Replacing the battery
If the standby LED (4) and the LED (6) in the tip of the receiver (contact-free voltage display)
flash simultaneously, the battery voltage is in a critical state.
If the battery voltage of the receiver is too low, the standby LED (4) will not illuminate.
In both cases, replace the 9 V block battery.
To this end, open the battery compartment (5) by pulling down the cover (see arrow symbol on
the cover).
