Setup and Installation
The MERTTURM cabinet light offers two convenient installation methods:
- Adhesive & Metal Strip Installation:
- Clean the desired surface thoroughly to ensure it is dry and free of dust or grease.
- Peel off the protective film from the adhesive strip and attach it to the chosen surface.
- Attach the metal strip to the adhesive strip.
- The light unit can then be magnetically attached to the metal strip. This allows for easy removal for charging or repositioning.
- Direct Magnetic Adsorption:
- If your desired surface is made of iron or a magnetic material, the light can be directly adsorbed onto it without the need for the adhesive or metal strips.

Maintenance
To ensure the longevity and optimal performance of your MERTTURM cabinet light, follow these maintenance guidelines:
- Cleaning: Wipe the light gently with a soft, dry cloth. Do not use abrasive cleaners, solvents, or harsh chemicals, as these can damage the surface or electronic components.
- Avoid Water: This product is not waterproof. Do not expose it to water, high humidity, or rain. Clean only with a dry cloth.
- Battery Care: For best battery life, avoid completely draining the battery frequently. Recharge the light when the indicator shows red. If storing for an extended period, charge the battery every 3-6 months.

Troubleshooting
If you encounter any issues with your MERTTURM cabinet light, please refer to the following common problems and solutions:
- Light does not turn on:
- Check if the battery is charged. Recharge the light if the indicator is red or off.
- Ensure the light is not in 'Always Off' mode (long press S2 to toggle power).
- Verify that the sensor is not obstructed.
- Motion sensor not working:
- Confirm the light is in 'All-Day Motion Sensor' or 'Light & Motion Sensor' mode (short press S2 to cycle modes).
- Ensure there are no strong light sources directly hitting the sensor in 'Light & Motion Sensor' mode.
- Check for any obstructions blocking the sensor's field of view.
- Light flickers or is dim:
- The battery may be low. Recharge the light fully.
- Adjust the brightness setting by long pressing the S1 button.
- Battery life is shorter than expected:
- Frequent activation in high-traffic areas will consume more battery.
