1. Introduction
Thank you for the purchase of this Carbon Dioxide Monitor, Carbon Dioxide is also known as CO2. This product is
designed for measuring CO2concentrations, as well as air temperature and humidity. To be used at home, office,
school, canteen etc. The CO2monitor adapts itself to its environment (auto calibrate). No settings need to be made.
This CO2Monitor alerts users through voice messages and audible alarms. Always avoid exposure to high
concentrations of CO2. This product, when used properly, is designed to alert you to elevated levels to CO2so that you
may take action to remove yourself from that environment.
•Accurate measurement of:
- carbon dioxide detection, ± 50ppm+5%
- temperature detection, ± 0.5°C or 0.9°F
- moisture detection, ± 5% RH
•Led status indication
•Voice alarm notification
•AUTO adjustment brightness of the display
•Rechargeable internal backup battery (± 12 hours)

3. Where to install the device?
The CO2sensor needs a process that ADAPTS to the current environment. In order to achieve a more accurate detection
effect, it should continue to work for more than 24 hours after changing the use environment to complete the
automatic calibration. After the completion, the calibration will not be completed at the next startup.
Ideally, a device should be installed in every room containing a fuel-burning appliance and in a room where the
occupant(s) spend most time like the living room, bedroom and study or hobby room. The CO2monitor can be wall
mounted (eye level), use cable input A (see page 2) or placed on a cabinet or table/desk, use cable input B (see page 2).
4. Where not to install the device
In an enclosed space (for example in a cupboard or behind a curtain).
Where it can be obstructed (for example by furniture).
Directly above a sink.
Next to a door or window.
Next to an extractor fan.
Next to an air vent or other similar ventilation openings.
In an area where the temperature may drop below -5°C or exceed 50°C.
Where dirt and dust may block the sensor.
In a damp or humid location.
In the immediate vicinity of a cooking appliance.
5. Mounting (see page 2)
The CO2Monitor comes with screws and wall plugs for mounting on the wall.
Remove the CO2Monitor from the mounting plate, turn (11) counterclockwise approximate 15°.
Use the mounting plate to mark the drill holes.
After drilling, place the dowels in the holes and then screw down the mounting plate with the screws.
Switch on the back-up battery (10), fully charged is approximate 12 hours usage without adapter connection.
Connect the adapter to the CO2monitor (9) and a power outlet.
Place the CO2Monitor on the mounting plate and turn (12) approximate 15° clockwise.
6. Status indicator - Green / Yellow / Red

- 4 -
When ≤1000PPM, the warning window displays green colour.
When 1000PPM ~ 1500 PPM the warning window displays yellow colour
When ≥1500 PPM, the warning window displays red colour and emits 75db@1m alarm sound. Take recommended
actions to prevent damage to personal health and safety.
7. Explanation operation buttons
Short press to switch between temperature, humidity and CO2display.
Short press to get temperature display and then long press to set degrees Celcius or degrees
Fahrenheit.
Short press to get CO2display and then long press to set alarm sound ON/OFF.
Long press to test the alarm.
Short press to delay/hush the alarm for 10 minutes.
Press and hold both keys simultaneously for 3 seconds. You will hear the voice message in the
set language. Press again for 3 seconds and the menu moves to the next language.
8. Recommended actions when the CO2Monitor warning has been activated
Keep calm.
Open all doors and windows and turn off all combustion appliances.
If the CO2Monitor continues to sound the alarm, evacuate your home.
Leave all doors and windows open and do not enter until the alarm has stopped.
Seek medical attention for anyone who may be suffering from the effects of carbon dioxide poisoning.

9. Carbon dioxide levels and guidelines
400PPM Normal outdoor air level
400 ~ 1000PPM Typical level indoors with good ventilation.
NOTE: If CO2levels are low when building is sealed and occupied, check for overventilation
(too much fresh air = energy wasted).
>1000PPM ASHRAE and OSHA recommended maximum level in a closed room.
Considered maximum comfort level in many countries.
>1200PPM Poor air quality - requires ventilation.
>2000PPM According to many studies this level of CO2produces a significant increase in drowsiness,
tiredness, headache lower levels of concentration and increased likelihood of spreading
respiratory viruses like colds, etc.
>5000PPM OSHA and NIOSH first threshold for safety. Maximum allowed concentration within an 8
hour working period.
10. Maintenance
We recommend to manually test CO2Monitor once a month by pressing and holding the test button. Dust is a major
cause of false alarms. Therefore, clean the CO2Monitor once a month. Use a vacuum cleaner to gently remove any
accumulated dust along the sides of the CO2Monitor. Never use a wet cloth or detergent to clean your CO2Monitor.
Clean the device with a soft, damp and lint-free cloth. Make sure that no moisture enters the housing. Do not use any
sprays, solvents, alcohol-based cleaning agents or abrasive cleaners, but only clean water to moisten the cloth.
11. Warnings
This manual contains important safety information about the CO2Monitor.
Read the manual carefully and keep it in a safe place for future reference.
Do not open the device in case it is damaged.
Do not remove any safety signs, stickers or labels from the device.
Keep all safety signs, stickers and labels legible condition.
This product cannot be used in factories, warehouses and other industrial environments that may be in high CO2
concentration for a long time.
If the product is to be placed in a narrow space, the space should be well ventilated, especially the two diffusion
windows should be in a well-ventilated position.
The product should be away from heat source, and avoid direct sunlight or other thermal radiation.
This product should not be used in the environment with high dust density for a long time.
