Setup and Installation

Follow these steps to properly install your APT USB CD Player:

1. Choose a Mounting Location: The unit can be mounted vertically or horizontally. Consider placing it on your center console, in your glove box, or any other location where the USB cable can comfortably reach your vehicle's USB data port. Ensure the CD slot faces upwards for proper disc insertion.
2. Secure the Unit: Use the included durable double-sided tape to secure the CD player in your chosen location. Ensure the surface is clean and dry before applying the tape for optimal adhesion.
3. Connect to USB Port: Locate an available USB data port in your vehicle. Plug the USB cable from the APT USB CD Player directly into this port. No additional wiring or tools are required.
4. Initial Indexing (Crucial Step): After connecting, insert an audio CD into the player. It is VERY IMPORTANT to allow 20-30 seconds for the CD player to finish indexing the disc. This process ensures complete installation and helps avoid setup issues.

Maintenance

To ensure the longevity and optimal performance of your APT USB CD Player, consider the following maintenance tips:

• Cleaning: Keep the exterior of the unit clean by wiping it with a soft, dry cloth. Avoid using abrasive cleaners or solvents.
• Disc Handling: Always handle CDs by their edges to prevent fingerprints and scratches. Store discs in their cases when not in use.
• Environment: Avoid exposing the unit to extreme temperatures, direct sunlight for prolonged periods, or excessive moisture.
• Ventilation: Ensure the unit is not obstructed in a way that would block any ventilation points, although this device typically generates minimal heat.

Troubleshooting

If you encounter issues with your APT USB CD Player, try the following troubleshooting steps:

• Player Not Recognized:
  • Ensure the USB cable is securely plugged into both the CD player and the vehicle's USB data port.
  • Verify that your vehicle's USB port is functional by testing it with another USB device (e.g., a USB flash drive).
  • Try plugging the CD player into a different USB port in your vehicle, if available.
  • Restart your vehicle's infotainment system (refer to your vehicle's manual for instructions).
• CD Not Playing / Skipping:
  • Ensure the CD is clean and free of scratches or smudges.
  • Verify that the CD was fully indexed during the initial setup. If the process was interrupted, insert a different CD and repeat the installation steps from the beginning.
  • Try a different audio CD to rule out a faulty disc.
  • Ensure the player is mounted securely and not subject to excessive vibrations.
• No Sound:
  • Check the volume level on your vehicle's audio system.
  • Ensure the correct audio source (USB/Aux) is selected on your vehicle's radio.
