My hand control went "dead." Batteries were the originals, branded "GP." Rechargeble NiMH rated at 1.2v. Legacy is about 9 months old.
I tried non-rechargeble Rayovac alkaline AAs, rated at 1.5v (Not in the charging base, of course!).
Then some rechargebles I have on hand. Also Rayovac. NiMH rated at 1.2v.
Both kinds bring the controller to life, but it isn't working "properly" with either! For example, it won't completely turn off. Holding the power button down blanks the screen but the backlight will not turn off. It will not come back on either, without removing the batteries and re-inserting them??
I've put the original "GP" batts back in. Same result now.
Replacing batts should not be this hard??
