Rechargeable Batteries
Battery message:
'Battery OK':
'Battery Low':
Measurements are possible
The battery needs to be recharged,
measurements are still possible
Battery installation:
This device is supplied with Li-ion 18650 3.7V rechargeable battery *3 pcs.
Please confirm whether batteries + polarity are Li ion18650 positive bump specification and install batteries in
the correct polarity. If the battery polarity is reversed, the capacity will be insufficient and the battery life will be
shortened.
Battery charging:
The charge lamp (○
(5V/1A USB adapter charger)
Note: During battery charging, the temperature of the device will rise by 5°C~10°C. At this time, the
measurements of temperature and humidity will be affected by temperature rise. Cause an impact on
the accuracy of temperature when charging, please use a fan to blow toward the temperature sensor
(○
) directly in order to get a compensated balance of temperature and humidity between temperature

sensor and surrounding area.
Safety Instructions
Warning: Your safety is very important to us. To ensure to use the device correctly and safely, we would like
to draw your attention to read the warning and entire User Manual before using the device. These
are important safety information and should be observed at all times.
1. Please handle the device lightly, do not subject the device to impact or shock.
2. Do not immerse the device in water. Water can cause electric shock, fire or malfunction which may result in
damage.
3. Do not keep the device under the hot and moisture environment. Keep the device away from the heat source
or near water.
4. Please use a standard USB power supply (such as PC's USB port, universal AC adapter with USB port).
Improper power supply can cause serious damage to the device, or result in injury or death to the user.

) to return to the main screen.
2. During battery charging, the temperature of the device rises. The temperature and humidity sensors are
affected. At this time, measurements are only for reference. After batteries are fully charged and the device
cools down, measurements are reliable.
3. Repair – Do not attempt to repair the device or modify the circuitry by yourself. Please contact with the local
dealer or a qualified repairman if the device needs servicing.
4. Caution – The CO and NH3 sensors must be replaced every 3 years.
5. Cleaning – Disconnect the power before clean. Use a damp cloth, do not use the liquid cleaning agent, such
as benzene, thinner or aerosols.
