Setup Instructions
1. Unpacking and Inspection
Carefully remove all components from the packaging. Inspect the light fixture, power adapter, and adjustable brackets for any signs of damage. If any parts are damaged or missing, do not proceed with installation and contact customer support.
2. Attaching the Adjustable Brackets
Slide the adjustable brackets onto each end of the light fixture. Ensure they are securely attached. The brackets are designed to extend, allowing the light to fit tanks between 90cm and 106cm.

3. Positioning the Light
Place the light fixture with the attached brackets onto the rim of your aquarium. Adjust the brackets to fit your tank size, ensuring the light is centered and stable. The taller design of the brackets helps illuminate every corner of the tank.
4. Power Connection
Connect the power adapter to the light fixture and then plug it into a suitable power outlet. Ensure your hands are dry before handling electrical connections.
Operating Instructions
1. Controller Overview
The light is controlled via an inline controller with a digital display and several buttons for setting time, brightness, and color modes.

2. Setting the 24/7 Mode (Sunrise/Daylight/Sunset/Moonlight)
The 24/7 mode simulates natural light cycles with gradual transitions. This mode is programmable for specific start and end times for different light phases.
Video: A guide on setting up the 24/7 mode for a SEAOURA aquarium light controller (model SR-657 shown, but similar functionality applies to SR-653). The video demonstrates how to long-press the 24/7 button to enter settings, adjust start and end times for sunrise, daytime, sunset, and night modes using up/down arrows, and save settings by pressing the mode button. It highlights the gradual light changes between phases.
3. Preset Timer Modes
The light offers 3 preset timer options: 6 hours, 8 hours, and 12 hours. These timers automatically turn the light on and off daily at the specified duration, maintaining a consistent cycle.

4. WRB 3-Channel Customization
You can customize the intensity of the White (W), Red (R), and Blue (B) LED channels independently. This allows for fine-tuning the light spectrum to suit specific plant growth needs or to enhance fish coloration.

5. Preset Color Options & Brightness Adjustment
The light offers 11 preset color options and 10 levels of brightness adjustment. You can cycle through these options to find the ideal aesthetic for your aquarium.

Maintenance
The SEAOURA SR-653 is built with durable ABS housing designed for efficient heat dissipation, ensuring stable performance and prolonging LED life. Regular cleaning of the light fixture's exterior with a soft, damp cloth is recommended to prevent dust and mineral buildup, which can affect light output. Always unplug the light before cleaning.
Temperature Monitoring and Alarm
The controller includes a temperature monitoring feature with an alarm. This allows you to set high and low temperature thresholds for your aquarium. If the water temperature exceeds these thresholds, an alarm will sound, alerting you to potential issues.
Video: A demonstration of the SR-659 controller's temperature monitor and alarm setup (similar functionality to SR-653). The video shows how to access the temperature display, switch between Celsius and Fahrenheit, enable/disable the alarm, and set high and low temperature thresholds. It also demonstrates how the alarm triggers when the temperature exceeds the set limits and how to silence it.
