Operating Instructions
LED Indicators:
- Green LED (Power Indicator): Blinks periodically to indicate normal operation and sufficient battery power.

Test/Silence Button:
Press the large central "TEST/SILENCE" button to:
- Test Functionality: A short press will activate the alarm sound to confirm it's working. The alarm tone is over 85 dB at 3 meters.
- Silence Alarm: If a non-emergency alarm occurs (e.g., from cooking smoke), press and hold the button to temporarily silence the alarm for 10 minutes. The alarm will automatically reset after this period if the condition clears.
CO Alarm Sensitivity:
The CO sensor is calibrated to specific carbon monoxide concentration levels and exposure times:
- 30 PPM: No alarm before 120 minutes.
- 50 PPM: Alarms between 60 and 90 minutes.
- 100 PPM: Alarms between 10 and 40 minutes.
- 300 PPM: Alarm in less than 3 minutes.

Maintenance
- Battery Life: The built-in lithium battery provides approximately 10 years of continuous operation. The device will indicate a low battery warning when replacement is needed.
- Cleaning: Regularly clean the detector to prevent dust and debris buildup, which can affect performance. Use a soft, damp cloth to wipe the exterior. Do not paint the unit.
- Testing: Test the alarm weekly by pressing the "TEST/SILENCE" button to ensure proper functionality.

Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Alarm sounds frequently without apparent reason. | Dust buildup, cooking fumes, high humidity, or proximity to steam/smoke sources. | Clean the detector. Relocate the detector away from cooking areas or bathrooms. Use the silence function if it's a false alarm. |
| Yellow LED flashes or chirps periodically. | Low battery warning or a fault in the unit. | The battery is non-replaceable. If the unit is chirping due to low battery after 10 years, replace the entire unit. If it's a fault, contact customer support. |
| Alarm does not sound during test. | Unit not properly activated or faulty. | Ensure the unit is correctly twisted onto its base. If still no response, the unit may be faulty and needs replacement. |
