hanwarlal told reporters that some EVMs received from Electronic Corporation of India Limited (ECIL), Hyderabad were in factory mode and the polling staff was unable to use them.
He, however, said such EVMs were replaced in 20 minutes to half-an-hour as every district has 2,000 EVMs in reserve.
"There was a small technical snag in new EVMs. They are in factory mode and they have to be sent back to the factory but we have sufficient number of machines for immediate replacement," he said.
The election authorities are using 100,000 EVMs. The CEO said these were new machines which arrived two days ago from ECIL and Bharat Electronics Limited (BEL).
