thnx Tom, if all else fails I might just drop the 25$I have the 701 manual - Casiotone 701 Textbook & a Technical_Guide_For_CasiotoneYet no trouble shooting guild, which I would hope would be in the service manual.Though also know MANY trouble shooting guilds are balls... So not looking to find out @ 25$If all else fails I guess I will have no choice. Well maybe sell the rig and get one that works.This one was suppose to work, and was shipped VERY lax, and got damage.I payed 151& yet got back 90 & AM thinking I should've got more...I would like to mod. it though too...Thnx again Tom
