I use the TWA occasionally really. Sometimes I won't use it for several weeks. If that's the case, the batteries will always be empty. Yes, I do know that it'd be better to remove the batteries when I'm not using then regularly,
But still: what could be draining the batteries when the device is off? And is there anything I can do about it (other than always removing the batteries after playing)?
That is strange! If the TWA is powered off, it should not drain the batteries. How old is your unit? Shoot us an email at firstname.lastname@example.org and we can help determine if a repair is in order for your unit.
it's been a while - my invoice shows 07/28/2016. :-)
FWIW, I've had the problem since the beginning and I've been through a few firmware updates, so this is nothing that came up due to one of those updates.
Shoot me an email at email@example.com and I can connect ya with Bruce, our engineer, to determine if it's a hardware issue causing the battery drain!
