Officials said engineers from the Electronics Corporation of India Limited (ECIL) would be present in the counting centres to immediately provide technical assistance in the event of malfunctioning of EVMs.
One counting observer has also been appointed for each Assembly constituency. Altogether 78 companies of central armed forces are guarding the strong rooms where the EVMs are kept after the end of polling, officials said.
The day after counting ends, all central security forces will leave the state. Top officials of the Election Commission in Delhi will hold a review meeting tomorrow with the returning officers through video conferencing.
