You can plug in the host to check the power in the handle settings. If the battery is exhausted, you need to connect the power cord to charge the game machine, or you can plug the handle into the seat to charge it.
However, you must have an extra handle, otherwise you can't control the game while charging. The indicator light of the switch handle is not lit, indicating that there is no electricity.
The witch's right hand handle can't be identified separately if the light is off, because the thinking program host is identified by the display and flashing of the handle indicator light according to the settings of your handle and various key sounds. If all the indicators are turned off during the setting, there is no way to display the video through the indicators, only the result of manual operation, so don't turn off the lights casually after the adjustment is completed.
