- 3 Pop out the old coin cell, noting its orientation.
- 4 Insert the new battery the same way up, then snap the case shut.

Battery tips
- Use a fresh, name-brand 3V lithium cell — bargain cells drain quickly.
- Try not to touch both faces of the new battery; skin oils shorten its life.
- If the buttons still don't respond after a new battery, the remote may need re-syncing or programming.
