ignition timing

how do I set the ignition timing on a 1994 mazda protege? The timing mark is way down on the crankshaft pulley. How do I know which mark is which? There is no way to read the numbers, etc. I know to use a jumper wire between the TEN and GND of the test connector. I can buy an induction timing light, but how in the world do you know which notch of the timing indicator to use?? THANK YOU FOR YOUR HELP!
