I have my unit for 1 month before experience the `` f61 '' many people have see . I call they repair shop back and forth during a period of 4 month and it seem that none of the part that Panasonic send they could fix the unit . to this date , I still can not get Panasonic to send I a refurbish unit . on top of that , I have to drive the unit 97 mile to the nearest repair shop . I would not recommend this product due to the terrible customer service when it come to service the warranty .
