Check that there is a fully working battery in the unit. If it is a rechargeable battery then make sure that it is charged. Ensure the battery cap has located correctly and is screwed down properly.

You can providing you leave the lens cap on. There is a tiny hole in the lens cap to enable this but we would not advise it because it will shorten the life of the tube.
