Setup
1. Battery Installation
The remote control typically comes with a pre-installed battery. If replacement is needed, use a CR2032 coin cell battery. To replace:
- Locate the battery compartment on the back of the remote.
- Use a small coin or screwdriver to gently pry open the compartment cover.
- Remove the old battery and insert the new CR2032 battery with the positive (+) side facing up.
- Securely close the battery compartment cover.
2. Programming the Remote Control
To program your remote to your garage door opener, follow these steps. Ensure you have access to your garage door opener motor unit.
- Locate the Learn Button: On your garage door opener motor unit (usually mounted on the ceiling of your garage), locate the 'Learn' button. This button is typically colored (red, orange, purple, or green) and may be behind a light cover.
- Activate Learn Mode: Press and immediately release the 'Learn' button on the garage door opener. The LED indicator next to the 'Learn' button will illuminate steadily for 30 seconds, indicating the opener is in programming mode.
- Program the Remote: Within 30 seconds of pressing the 'Learn' button on the opener, press and hold the button on your 139.53753 remote control.
- Confirm Programming: Release the remote control button when the garage door opener's light bulb flashes or you hear two clicks. This indicates successful programming.
- Test the Remote: Press the remote control button again to test if it operates the garage door.
