- Field Disturbance Sensor Rejection (FDSR): Recognizes and filters out false alerts caused by lane departure and collision avoidance systems in newer vehicles.
4.6 Signature ID Features
- Radar Signature ID (RSID): Displays specific Ka-band radar frequencies (e.g., Ka 33.8, 34.0, 34.3, 34.7, 35.5) when detected.
- Laser Signature ID (LSID): Indicates the Pulses Per Second (PPS) transmitted by speed laser or other laser sources.
4.7 Other Features
- POP Mode Detection: Detects brief bursts of radar used for instant speed measurement.
- Bilingual Voice Alerts: Provides audible alerts in both English and Spanish.
- Bilingual OLED Text Display: Displays information in English or Spanish.
- Vehicle Battery Saver: Automatically turns off the detector if the vehicle's ignition is off for an extended period.
5. Maintenance
To ensure the longevity and optimal performance of your Whistler CR93, follow these maintenance guidelines:
- Cleaning: Use a soft, damp cloth to clean the exterior of the detector. Do not use abrasive cleaners or solvents.
- Storage: When not in use, store the detector in a cool, dry place away from direct sunlight and extreme temperatures.
- Cable Care: Avoid kinking or pinching the power and USB cords.
6. Troubleshooting
If you encounter issues with your CR93, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Detector does not power on. | No power from 12V outlet; faulty power cord. | Check vehicle's 12V outlet fuse; ensure power cord is securely connected. |
| Frequent false alerts. | Operating in City mode in a rural area; interference from other vehicle systems. | Switch to a City mode (City 1 or City 2) or enable TFSR/FDSR features. |
| No GPS alerts. | Outdated GPS database; poor GPS signal. | Update GPS database via USB; ensure clear view of the sky for GPS reception. |
| Weak detection range. | Obstructed view; operating in City mode on highway. | Ensure clear line of sight; switch to Highway mode for maximum sensitivity. |
