How To Sealing EVM CU BU and VVPAT : Sealing Process of EVM and VVPAT
1. The Electronic Voting Machine (EVM) is a reliable system for conduct of elections in which one
person has to be elected out of many candidates.
2. EVM consists mainly of two units – (a) Control Unit (CU) and (b) Balloting Unit (BU) with cable
for connecting it with the Control Unit. A Balloting Unit caters upto 16 candidates. Four Balloting
Units linked together catering in all to 64 candidates can be used with one Control Unit.
3. EVM uses a modern microcomputer and other Large Scale Integration (LSI) chips. It operates on a
special Power pack. It is tamper-proof, error-free and easy to operate. It is easily portable. The
polling information once recorded is retained in its memory even when the Power pack is
removed.
4. The machine, which is according to the design approved by the Election Commission of India, is
manufactured by Bharat Electronics Limited (BEL) and Electronics Corporation of India Limited. It
is the end product of considerable experience and extensive trials in Indian Elections under the
guidance of the Election Commission of India.
5. This chapter aims at introducing the machine and familiarising the electoral officials with its
functioning.

be opened by pressing the latches simultaneously, on both sides of the handle, as shown in

‘Ballot Button’ on the Control Unit is pressed by the Presiding Officer to enable the voter to record
his vote. It goes off when the voter has recorded his vote.
13. The Slide Switch Window is on the top right side. The Slide Switch inside the Balloting Unit can

window of that Unit, and so on.
