Note: After charging is complete, disconnect the cable and securely close the waterproof cap.

Powering On

Double-press the power button to turn the camera on or off. When powered on, the blue indicator will light up.

Pre-Installation Test

Before installation, ensure the WR2 camera and receiver are working properly. (The camera and receiver are pre-paired before shipment.)

1. Connect the receiver box to your ATOTO head unit or Portable Smart CarPlay Display (PSCD).
2. Open the WRC app. The camera feed should appear within a few seconds.
3. By default, the camera operates in Power-Saving Mode and will automatically exit the WRC App after 2 minutes.

If the camera is not paired:

1. Press and hold the receiver’s WAKE/PAIR button until the blue light flashes rapidly.
2. Then press and hold the camera’s power button until the red light appears and changes to fast blue flashing.
3. When pairing is successful, the blue indicator light will turn solid.

WRC App

If your device does not have the WRC App preinstalled, download and install it on your car stereo or PSCD.

Ensure that the receiver box is properly connected and that its indicator lights are functioning normally (both the camera and receiver box should show a solid blue light when ready).

Once everything is set up, open the WRC App.

Troubleshooting

7.1 No Video or Connection Issues

If the camera takes a long time to display video on your car stereo or PSCD, frequently freezes or buffers, or fails to show any video, the issue may be caused by a weak wireless signal between the camera and the receiver box. Connection interference can be caused by structural elements of your vehicle.

How to Improve Wireless Signal:

• Adjust the receiver’s antenna

Open the WRC app and check the signal strength. If it is below 60%, try rotating the receiver’s antenna in different directions to improve the signal to 60% or higher.

• Reposition the camera

Rotate and adjust the camera’s vertical angle. Adjust the distance between the antenna and the vehicle’s trunk metal. Try to point the antenna toward the sky.

Remove the camera from its bracket and temporarily flip it upside down. Reinstall the camera on the license plate or in a different location. When the camera is mounted with the ATOTO logo facing downward, it will automatically flip the video on your display device to ensure the image is correctly oriented. Flipping the camera may change the position of the wireless antenna and, in some cases, improve connection quality.

7.2 Cold Weather Issues

Low temperatures may reduce battery performance and affect connection. If the battery is below 20%, recharge the camera.

7.3 Camera Paired but No Video Display

If the camera’s battery is fully charged and the indicator light is slow-blinking blue, but no video appears on your car stereo or PSCD, follow these steps:

Possible Cause: Camera Not Paired Successfully

Solution: Press and hold the WAKE/PAIR button on the receiver box for 3 seconds to enter pairing mode. The receiver’s indicator light will change from slow-blinking blue to fast-blinking blue and remain in pairing mode for 15 seconds. If pairing is successful within this time, the light will turn solid blue.

Camera Pairing Process:

Press and hold the camera’s power button for 3 seconds to enter pairing mode. The indicator light will briefly turn red, then switch to fast-blinking blue. Once pairing is successful, the light will turn solid blue.

After Successful Pairing:

Open the WRC App on your car stereo or PSCD. The camera feed should appear in the app. By default, the camera operates in Power-Saving Mode and will automatically exit the WRC App after 2 minutes.

7.4 Unstable Signal or Intermittent Connection

Possible Causes:

The camera and receiver are installed beyond the effective wireless range.

There are metal structures or enclosures between the two devices that interfere with signal transmission.

Recommended Solution:

For optimal performance, install the camera and receiver within an open-air distance of approximately 7 meters (23 feet).

Avoid placing large metal objects or multiple layers of metal (such as trailer walls, toolboxes, or vehicle frames) between the camera and receiver.

If the layout limits placement options, consider repositioning the receiver closer to the camera to maintain a clear signal path.
