LED in door button
The LED light in the door button is used to indicate that
an “ON” signal is being sent to the receiver. When the
receiver receives the signal, the selected gong tone
will be played.
Replacing battery
The battery life depends on how often the door button is
operated and how low the ambient temperature is.
If there is insuffi cient power remaining in the battery,
the LED light will be dim and the receiver will not react
to the button. In this case, the user should replace the
battery.
