3. Setup and Installation
3.1 Choosing a Location
For optimal performance, install the detector in areas where carbon monoxide or smoke may accumulate. This includes living rooms with stoves or wood fireplaces, kitchens, bedrooms, bathrooms, garages, cellars, and during travel in hotels or RVs. Ensure the device is placed where its display is easily visible and its alarm can be heard.
- For CO Detection: Place at breathing level, typically 1-1.5 meters (3-5 feet) from the floor.
- For Smoke Detection: Place higher on a wall or ceiling, away from air vents or fans that might interfere with smoke reaching the sensor.
- Avoid placing near windows, doors, or areas with high humidity or extreme temperatures.

6. Troubleshooting
If you encounter issues with your Gedsffati HD11 detector, refer to the following common solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on when plugged in. | No power from outlet; device malfunction. | Check the power outlet with another device. Try a different outlet. If still no power, contact support. |
| Alarm sounds without apparent hazard. | False alarm; sensor contamination; actual low-level hazard. | Press the Buzzer button to silence. Ventilate the area. Clean the device. If alarms persist, evacuate and seek professional help. |
| Display is blank or dim. | Screen brightness set to off; low battery; device malfunction. | Short press the Screen Brightness button to adjust. Plug the device into an outlet to charge. If problem persists, contact support. |
| Inaccurate temperature/humidity readings. | Placement near heat/cold source; sensor interference. | Relocate the device away from direct sunlight, heating/cooling vents, or high humidity sources. |
