Carbon dioxide(CO2) is a colorless and odorless gas usually derived
from the breath of humans and animals. High CO2 concentration
means that fresh air or ventilation is required; otherwise, it may
cause problems such as drowsiness, dizziness, loss of attention,
and cognitive impairment.
Temperature & Humidity may often be ignored. However, they do have
a significant impact on an individual's well-being, comfort, health
and safety, as well as your property. High Humidity may lead to an
increase in household air pollutants, especially the biological contaminants
such as molds, bacteria, viruses, and dust mites; cold, low Humidity
may cause nosebleeds, skin and respiratory irritations, dyspnea, static
electricity, etc.

Do not expose the detector to heavily contaminated environments for long
periods, as this can damage the sensor.
Do not use the detector for long periods in environments with a strong, irritating
smell to ensure accurate measurements.
Do not dismantle the unit yourself. In the event of a defect, contact your dealer
instead, who will liaise with the service center and, if necessary, send the
device in for repair.
Children should only use this device under adult supervision. Keep packaging
materials, such as plastic bags and plastic wrap, out of the reach of children
as they present a choking hazard.
If the battery level shows , please charge the detector in time to avoid
being aected during use (it can also recharge when switched o).
This product is intended for monitoring the health of the indoor environment
only and should not be considered a professional measurement tool.

Switch on the detector in an outdoor ventilated area; Long press the and to
enter the calibration state, the CO2 title on the screen flashes, the CO2 display area starts
to count down 200 seconds; the countdown ends, and the calibration is complete.
During manual calibration, the monitor must be exposed to fresh outdoor air (approx. 400
ppm of CO
2) at least 1 meter away from people or animals.
In calibration mode, press the button to stop calibration mode.
Please ensure the power supply is sucient during the calibration process. If the calibration
mode is forcibly excited due to shutdown or power failure, the calibration may fail, and the
data will be inaccurate, so you need to re-calibrate.
Press and hold the and buttons for 2 seconds.

FAQ
17

Q: Why are there two modes?
A: We oer two modes to cater to dierent usage scenarios. Mode is suitable for
situations where real-time monitoring of environmental parameters is needed. It
has a higher data collection frequency but shorter battery life. This Mode is best
suited for scenarios with frequent ecological changes, such as traveling. For regular
usage, we recommend selecting the mode. The mode is designed for long-term
monitoring, oering a longer battery life but a lower data collection frequency.
Choose the Mode that best suits your specific needs.
Q: Why does Mode have a shorter battery life?
A: Mode has a higher data collection frequency, with data being collected every
minute. Therefore, it has a relatively shorter battery life.
18

Q: If I need to monitor CO2 data for an extended period continuously, will this
impact the device's lifespan?
A: According to Temtop Laboratory's testing, continuous real-time monitoring of CO2
data for an extended period has a negligible impact on the device's lifespan.
Q: Why is CO2 data high?
A: The user's environment may be poorly ventilated, resulting in high CO2 concentration;
it is recommended that the user place the product in an outdoor ventilated place for
10 minutes. If the data is still high, the customer is advised to calibrate according to
the user manual.
Q: Why is the temperature high when charging?
A: The temperature and humidity sensor is located inside the product. When charging,
a large amount of heat will be generated, causing the actual temperature of the product
to rise.
