4. Operating Instructions
Your BRIKSMAX light kit can be powered using the included AA Battery Box or via the USB power cable.
4.1 Powering the Light Kit:
- Using the AA Battery Box: Insert the required number of AA batteries (not included) into the battery box, observing correct polarity. Connect the battery box to the main power input of the light kit. Use the switch on the battery box to turn the lights on or off.
- Using the USB Power Cable: Connect the USB cable to the main power input of the light kit and plug the other end into a compatible USB power source (e.g., a USB wall adapter, power bank, or computer USB port). The lights will typically illuminate automatically when power is supplied.
Ensure the power source provides stable voltage to prevent damage to the LED components.
5. Maintenance
Proper maintenance ensures the longevity and optimal performance of your light kit.
- Cleaning: Gently dust the LED components and wires with a soft, dry cloth. Avoid using liquid cleaners directly on the lights or wiring.
- Handling: Always handle the light kit components and wires with care to prevent bending, breaking, or disconnecting.
- Storage: If disassembling the light kit for storage, carefully coil wires and store components in a dry, cool place away from direct sunlight.
- Power Source: When not in use for extended periods, disconnect the power source (remove batteries or unplug the USB cable) to conserve power and prevent potential issues.
6. Troubleshooting
If you encounter issues with your BRIKSMAX light kit, please refer to the following common solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Lights do not turn on. | No power, loose connection, faulty component. | Ensure batteries are correctly inserted or USB cable is securely connected to a working power source. Check all wire connections. If problem persists, contact support. |
| Some lights are not working. | Damaged wire, loose connection, faulty LED. | Inspect wires for kinks or breaks. Re-seat connections. If a specific LED is faulty, contact support for replacement options. |
| Lights flicker or dim. | Low battery power, unstable power source, loose connection. | Replace batteries or try a different USB power source. Check all connections for tightness. |
| Wires or components do not fit properly. | Incorrect placement, tight space. | Refer to the detailed paper instructions and installation video. Gently adjust LEGO bricks to create space for wires. Avoid forcing components. |
| Wing strips or other flexible lights detach easily. | Insufficient securing, movement. | Ensure the strips are firmly pressed into place. If possible, use small, clear adhesive dots or additional small LEGO elements to secure them without obstructing light. |
