SANYO home electric fan remote control with wind speed adjustment and timer functions. - Model Name: EF-30CHR - Brand: SANYO - Battery Type: CR2002 Button Operation ・On/Off → ○ ・Timer → ○ ・Sleep → × ・Wind Speed → × Two of the four buttons did not work. Also, the buttons that do work need to be pressed a little harder than usual. For these reasons, I am selling this item as junk. Thank you for your understanding.
