User Tips:

1. It is normal for FM products to exhibit some noise due to interference from the local radio signal. Find a clear or undisturbed frequency and synchronize the device to that frequency to minimize static noise.

2. For the best audio quality, please set the volume on your phone or device to maximum and then adjust the volume on your car radio. It is not recommended to set your car speaker volume to maximum (this will result in excessive noise).

3. We recommend that the RAM be less than 32 GB. A RAM larger than 32 GB may lead to abnormal readings.

4. Our products support the use of a standard 12-24V car/truck battery. We recommend that you do not use the product in a car/truck with a modified battery. This may cause burns due to the high currents.

5. To protect this device, we recommend removing it from the cigarette lighter socket after use to prevent immediate damage from high starting voltage.
