do we need to cover the reciever in black plastic bag or any carbon paper or any such material?

Is it necessary to use the TATA SKY in India for 2-3 days and then bring it here.In one of the post above i read so.
[After buying can I bring it here without setting up/using it in India,box pack or do i need to instal in India 1st and then bring.]

Thanks,
