Setup

The NEC RE0209 remote control requires two (2) AAA alkaline batteries (not included). Follow these steps to install them:
- Locate the battery compartment cover on the back of the remote control.
- Slide the cover downwards or in the direction indicated by an arrow to open it.
- Insert two (2) AAA alkaline batteries, ensuring the positive (+) and negative (-) terminals align correctly with the markings inside the compartment.

Note: Always use new alkaline batteries for optimal performance. Do not mix old and new batteries, or different types of batteries.
2. Channel Selection (if applicable)
Some lighting fixtures may require channel selection to ensure proper communication with the remote. The RE0209 remote control features CH1 and CH2 buttons. If your light fixture has a channel setting, ensure the remote's channel matches the fixture's channel. Refer to your ceiling light's manual for specific channel setting instructions.

Cleaning
To clean the remote control:
- Wipe the surface with a soft, dry cloth.
