Precautions
1. Do not operate with power on. Always turn off the power before operating. Only power on after confirming that everything is working properly.
2. If the remote control battery voltage is low, please replace the batteries immediately. (A low battery voltage in the remote control generally reduces the control range.) 3. When using wireless electronic products, avoid strong interference sources such as metal covers, large electronic devices, and electromagnetic fields to prevent the remote control from being too close to the receiver or causing it to malfunction.
4. Do not use this electronic product improperly. Improper use can reduce product performance and lifespan, and in severe cases, damage the product and pose a safety hazard.
5. The delay time setting is automatically set when entering learning mode. The delay time setting is linked to the number of times the learning button is pressed. Please pay special attention to this.
