1. Product Overview
The Westek MLC12BC-4 is an indoor plug-in motion-activated light control designed to automate lighting and small appliances. It detects motion within its range and activates connected devices, turning them off after a user-defined delay. This device enhances convenience and can contribute to energy savings by ensuring devices are only active when needed.

2. Setup Instructions
Follow these steps to set up your Westek MLC12BC-4 motion-activated light control:
- Unpack the Device: Carefully remove the motion control unit and its components from the packaging.
- Set the Desired Off-Time: Before plugging in, locate the timer dial on the back of the plug-in power block. Use a small screwdriver or a similar tool to select the desired duration (1, 2, 5, 10, or 20 minutes) for the connected device to remain on after motion ceases.
- Plug into Wall Outlet: Insert the plug-in power block into a standard 120V AC wall outlet. An activation indicator light on the power block will illuminate.
- Connect Your Device: Plug the lamp or appliance you wish to control into the outlet on the power block. Ensure the device is switched to the 'ON' position if it has its own power switch.
- Position the Motion Sensor: The motion sensor is connected to the power block by a 6-foot cord, allowing for flexible placement.
- Tabletop Placement: Place the sensor in the included weighted base and position it on a table, counter, or any flat surface where it can best detect motion in the desired area.
- Wall Mounting: The sensor unit can also be mounted to a wall using appropriate screws (not included) through the designated holes on its back.
- Initial Calibration: Upon initial power-up, the unit may cycle on and off briefly. This is a normal calibration process for the sensor. Allow a few moments for it to stabilize.

3. Operating Instructions
Once set up, the Westek MLC12BC-4 operates automatically:
- Motion Detection: The sensor continuously monitors its detection zone for movement.
- Device Activation: When motion is detected, the connected light or appliance will turn on.
- Timer Function: The device will remain on as long as motion is continuously detected. After motion ceases, the timer will begin counting down. The device will turn off once the pre-set time (1, 2, 5, 10, or 20 minutes) has elapsed without further motion.
- Resetting the Timer: Any new motion detected during the countdown period will reset the timer, keeping the device on for the full duration of the selected off-time.

4. Maintenance
The Westek MLC12BC-4 requires minimal maintenance:
- Cleaning: Periodically wipe the sensor lens and the unit with a soft, dry cloth to remove dust or debris that may obstruct motion detection. Do not use liquid cleaners or abrasive materials.
- Inspection: Regularly check the cord and plug for any signs of damage. If damage is observed, discontinue use and replace the unit.
5. Troubleshooting
If you encounter issues with your Westek MLC12BC-4, refer to the following troubleshooting tips:
- Device Not Turning On:
- Ensure the power block is securely plugged into a live wall outlet.
- Verify that the connected lamp or appliance is properly plugged into the power block and its own power switch is in the 'ON' position.
- Check if the sensor is obstructed or positioned correctly to detect motion in the desired area.
- Confirm that the power outlet is functional by testing it with another device.
- Device Not Turning Off:
- Ensure there is no continuous motion within the sensor's detection zone.
- Check the timer setting on the back of the power block to ensure it is set to the desired off-time.
- Verify that the sensor lens is clean and free from obstructions that might cause false motion detection.
- Intermittent Operation:
- The sensor may be detecting motion from an unintended source (e.g., pets, drafts, objects moving in the wind outside a window). Adjust the sensor's position or angle.
- Ensure the sensor is not placed near heat sources or air vents, which can interfere with its operation.
