Help Needed With Sinclair 1000

Hello everyone. I have an old Timex Sinclair 1000 computer that I recently got at Salvation Army for $.50 (they thought it was an organizer!). I bought it to do a presentation in my school on BASIC, but can't quite figure out how ot get it to work. First of all, the display constantly has an (approxamately) 2" wide (I'm using a 13" TV) black bar that rolls from the top to the bottom -constantly. Would this be caused by using the wrong type of adapter? I'm using a 9VDC 100mA adapter. Is this too little? Too much? Secondly, I can't seem to get it out of shortcut mode. I try to type "10 CLS", and I get "10 CONT LET SAVE". I know that the Sinclair had shortcus for the functions, but how do I get to the normal data-entry mode? I took it apart, and the board in it has a Zilog Z80A, a Ferranti chip (same size as Z80), a removable Sinclair Research chip, and a Toshiba chip. It says SINCLAIR ZX81 1981 (c). Anyone have info on this *tiny* computer?
