Maintenance
Data Updates
To ensure the most accurate and up-to-date information, it is recommended to regularly update the GPS data and public enforcement information. These updates are available monthly for free download from the COMTEC website.
You will need to download the data to a microSD card and then update the unit. Refer to the COMTEC website for detailed instructions on the update process.
Cleaning the Unit
Gently wipe the unit's screen and body with a soft, dry cloth. Avoid using abrasive cleaners or solvents, as they may damage the display or casing.
Troubleshooting
If you encounter issues with your COMTEC ZERO 85M, please refer to the following common troubleshooting steps:
- No Power: Ensure the power cable is securely connected to both the unit and the vehicle's 12V power outlet. Check the vehicle's fuse for the power outlet.
- No GPS Signal: Ensure the unit has a clear view of the sky. GPS reception may be difficult in tunnels, underground parking, or dense urban areas. Allow sufficient time for the unit to acquire satellites after startup.
- False Radar Warnings: The unit features a "Radar Cancel Point Detection" function. If you frequently receive false warnings in a specific location (e.g., near automatic doors), you can register that location as a cancel point to mute future alerts there.
- Motion Sensor Not Responding: Ensure there are no obstructions in front of the motion sensor. Try performing the gestures clearly and deliberately.
- External Input Not Displaying: Verify that the optional ZR-09 AV input cable kit is correctly connected and that the external device (backup camera, DVD player) is powered on and functioning. Ensure the unit is switched to the external input display mode.
- OBD2 Data Not Displaying: Confirm that the optional OBD2-R2 adapter is correctly connected to both the unit and the vehicle's OBD2 port. Verify that your vehicle model is compatible with the OBD2 adapter.
If the problem persists after attempting these steps, please contact COMTEC customer support or visit their official website for further assistance.
