]....... and NO< YOU CAN NOT!!!! I am dealing with this problem as I write this... very frusterating... when it says you can slow change and you can not.....[:@]
If anyone has the answere please post up... I have tried holding battery type for 3 seconds.... there is NO SCREEN FOR CHANGING the timer. I have also pressed enter after starting the system..... It just trys to start the charge / discarge process.....
