This unit powers on and is in need of repair. When plugged in the standby light comes on. When turned on the digital display lights up as can be seen in pictures. Other than that I have no way to test it. All of the keys on the keypad are in good condition and depress and spring back up as they should. There is a sticker on the back with the serial number. The top of the casing is missing and the motherboard is not attached to the bottom.
