3. Setup
3.1 Battery Installation
- Locate the battery compartment on the back of the remote control.
- Slide open the battery cover.
- Insert two AAA batteries (not included), ensuring the correct polarity (+ and -) as indicated inside the compartment.
- Close the battery cover securely.
3.2 Pairing with Flood Light
The Ustellar remote control is designed to work seamlessly with compatible Ustellar 55W and 100W motion sensor flood lights. Typically, no manual pairing is required; the remote should function directly with the flood light upon battery installation.
- Ensure the flood light is powered on and within range of the remote control.
- Point the remote control directly at the flood light's sensor or receiver.
- Press any function button (e.g., ON) to test the connection.
If the remote does not respond, refer to the troubleshooting section or the specific manual for your Ustellar flood light model for detailed pairing instructions, if any are required.
4. Operating Instructions
This section outlines the basic and advanced functions of your Ustellar remote control.
4.1 Basic Functions
- Power ON/OFF: Press the ON/OFF button to toggle the flood light's power state.
- Adjust Brightness: Use the Brightness + or Brightness - buttons to increase or decrease the light output.
- Mode Selection: Press the MODE button to cycle through available lighting modes. Common modes include:
- Motion Sensor Mode: Light activates only when motion is detected.
- Always On Mode: Light remains on continuously.
- Dusk-to-Dawn Mode: Light automatically turns on at dusk and off at dawn.
4.2 Advanced Settings
- Timer Function: Press the TIMER button to set the duration for which the light remains on after activation (e.g., 1 min, 5 min, 10 min).
- Motion Sensor Sensitivity: Use the SENSITIVITY button (if available) to adjust how easily the motion sensor is triggered. Higher sensitivity detects motion from further away or with less movement.
5. Maintenance
5.1 Cleaning
To clean the remote control, gently wipe its surface with a soft, dry cloth. Do not use abrasive cleaners, solvents, or wet cloths, as these can damage the remote's finish or internal components.
5.2 Battery Replacement
When the remote control's range decreases or it becomes unresponsive, it is likely time to replace the batteries. Follow the battery installation steps in Section 3.1. Always replace both batteries at the same time with new ones of the same type (AAA).
5.3 Storage
If the remote control will not be used for an extended period, it is recommended to remove the batteries to prevent leakage and potential damage to the device.
6. Troubleshooting

- Remote is unresponsive:
- Check if the batteries are correctly installed with the proper polarity.
- Replace the batteries with new ones.
- Ensure there are no obstructions between the remote and the flood light's sensor.
- Confirm the flood light is powered on.
- Limited operating range:
- Replace the batteries.
- Ensure you are within the recommended operating distance and pointing the remote directly at the flood light.
