Each competitor must compete with assigned SI card (the same one for whole championship). Team leaders will receive SI cards in the event office during registration. SI cards must be returned to organizer after the competitorís last competition (usually PreO 2).
In case of SI failure competitor punch to the map by pin to a control decsription field. For example (as you can see on the right picture), SI on station 13, 17 and 19 doesnít work. Your answer is A, C and Z. The red spots show, how you woud punch by pin then. There is usually room for 30 punch in the SI-card, so be careful to multipunching.
In video Hanka is turning by carousel using the same hand where she has a SI card on it's finger. She is very familiar with SI, so she can do it this way. But there is a danger of accidently mispunching! If the SIcard approach to a hole on SI device for some critical distance, it can write the data into the SI card! The correct way is turning the carousel by other hand without SIcard!
