3. Opsætning og installation
3.1 Montering af detektoren
The Cobra XRS 9740 should be mounted in a location that provides a clear, unobstructed view of the road ahead and behind for optimal radar and laser detection. Use the provided windshield mounting bracket.
- Clean the windshield area where the detector will be mounted.
- Attach the suction cups to the mounting bracket.
- Press the suction cups firmly against the windshield to secure the bracket.
- Slide the detector onto the mounting bracket until it clicks into place. Ensure the detector is level and has a clear line of sight.
3.2 Strømtilslutning
Connect the coiled 12V DC power cord to the detector's power input jack and then into your vehicle's 12V accessory outlet (cigarette lighter socket).
3.3 Initial Compass Calibration
For accurate compass readings, the 8-Point Electronic Compass requires initial calibration. This procedure should be performed in an open area away from large metal objects or strong magnetic fields.
- With the detector powered on, drive your vehicle slowly in two complete circles (360 degrees each).
- The detector will automatically calibrate the compass during this process.
- Once calibrated, the compass display will show accurate directional headings.
4. Betjening

5. Vedligeholdelse
To ensure the longevity and optimal performance of your Cobra XRS 9740, follow these maintenance guidelines:
- Rensning: Regularly wipe the exterior of the detector with a soft, damp klæde. Brug ikke slibende rengøringsmidler eller opløsningsmidler.
- Linsepleje: Keep the front and rear laser lenses clean and free from obstructions. Avoid touching the lenses directly.
- Opbevaring: When not in use for extended periods, store the detector in a cool, dry place, away from direct sunlight and extreme temperatures.
- Strømledning: Inspect the 12V DC power cord periodically for any signs of damage. Replace if necessary.
- Montering: Ensure the suction cups on the mounting bracket are clean for a secure attachment to the windshield.
6. Fejlfinding
If you experience issues with your Cobra XRS 9740, refer to the following common problems and solutions:
| Problem | Mulig årsag | Løsning |
|---|---|---|
| Ingen strøm til enheden. | Power cord not properly connected; vehicle's 12V outlet is not functioning; blown fuse in power cord. | Ensure power cord is securely plugged into both the detector and the vehicle's outlet. Check vehicle's 12V outlet with another device. Inspect and replace fuse in the power cord if necessary. |
| Hyppige falske alarmer. | Operating in Highway Mode in urban areas; interference from other vehicle systems or automatic door openers. | Switch to City Mode (try different levels). Ensure IntelliShield False Signal Rejection is active. Reposition the detector if it's too close to other electronics. |
| Inaccurate compass readings. | Compass not calibrated; strong magnetic interference. | Perform the Initial Compass Calibration procedure (Section 3.3). Move the detector away from large metal objects or strong magnetic sources. |
| No radar/laser detection. | Detector is off; volume is too low; specific bands are disabled; obstructed view. | Ensure the unit is powered on and volume is audible. Check programming settings to ensure desired bands are enabled. Verify the detector has a clear line of sight to the road. |
