RE: Chargery Power Charger Problems
Here may be a helpful question if you have button beep turned on.
When you hold down the start button and it confirms the number of series cells you have correctly stated that you have to push the button again (don't have to hod it down this time) When you do push it again does it beep? If it doesn't beep then maybe it is a dirty button or bad button and needs wiggled or cleaned.
If it does beep then what happens to the screen? it doesn't start at all? Does the screen go blank and then repower up like starting over? If this is the case then check input voltage during the start process or try using it with a car battery for power.
