### HEAD ONLY — Rail Required

This listing does NOT include a garage door opener rail.

A compatible LiftMaster chain-drive rail must be purchased separately.

Rail length must be selected based on the garage door height.

Typical applications may require:

- 7' rail for a 7' high door
- 8' rail for an 8' high door
- 10' rail for a 10' high door
- Other compatible rail configurations where applicable

Always measure the garage door height and verify rail compatibility before ordering.

The opener cannot be installed or operated without the correct compatible rail system.

### Heavy-Duty DC Motor

The 4690L uses a heavy-duty DC motor designed for smooth and dependable residential garage door operation.

DC motor technology provides:

- Smooth acceleration
- Soft stopping
- Reduced vibration
- Quieter operation
- Controlled door movement

The garage door must still be properly balanced and mechanically sound. A powerful opener should never be used to compensate for broken springs, binding tracks, damaged rollers, or an improperly balanced door.

### Integrated Garage Camera

The built-in camera allows homeowners to monitor garage activity through the myQ app.

Camera features include:

- 360° adjustable viewing position
- Wide-angle garage coverage
- Night vision
- Live video
- Two-way audio
- Garage activity monitoring

Certain recording and advanced video features may require an eligible myQ Video Monitoring subscription.

### 2,000-Lumen LED Lighting

The integrated LED ring provides approximately 2,000 lumens of garage illumination.

The lighting design helps distribute light throughout the garage and can automatically activate when motion is detected.

### Built-In Wi-Fi & myQ

The 4690L connects directly to the myQ app through built-in Wi-Fi.

Compatible functions include:

- Open the garage remotely
- Close the garage remotely
- Check door status
- Receive activity notifications
- Monitor garage activity
- View the integrated camera
- Use myQ Diagnostics
- Manage compatible myQ accessories

An active internet connection and compatible smartphone are required.

### Battery Backup

The integrated battery-backup system allows the garage door opener to continue operating during a household power outage.

Battery backup makes the 4690L suitable for residential installations where battery-backed garage door opener operation is required.

### Security+ 3.0

The 4690L uses LiftMaster Security+ 3.0 wireless technology.

Security+ 3.0 provides encrypted communication between the opener and compatible remotes, keypads, and accessories.

Because this is a newer LiftMaster platform, older accessories should not automatically be assumed compatible.

Always verify accessory compatibility before ordering.

- Residential sectional garage doors
