concentration recorded Table standing or wall mounting Installation Push the power switch " " to “ON” to start the monitor, all monitor elements will be displayed and a signal sound is made. The monitor enters the normal working mode and 60-second countdown appears on the screen, indicating that the CO

sensor is warming up. When using the USB cable as DC power supply, the lithium battery inside the monitor will be charging. When the DC power is disconnected, the monitor will switch to the lithium battery as power source, or it can be start directly with the lithium battery as power supply. A fully charged lithium battery can last for about 20 hours of uninterrupted operation. Note: It is recommended to use DC power supply mostly and to only use the built-in lithium battery as back-up if needed. Manual settingEN4 In normal display mode, press and hold the "SET" button for 2 seconds to enter the time setting and the 12/24 hour time display flashes. Press the "UP" or the "DOWN" button to set the 12 or 24 hour time display. Press the "SET" button to confirm the setting and the hour flashes. Press the "UP" or the "DOWN" button to set the hour. Press the "SET" button to confirm the setting and the minute flashes. Press the "UP" or the "DOWN" button to set the minute. Press the "SET" button to confirm the setting and the alarm hour flashes.

Alarm and snooze function In normal display mode, press the "SET" button to activate or deactivate the alarm function. The alarm clock sounds for 1 minute, if no button is used. You can touch the “SNOOZE/LIGHT” touch field to enter the snooze function for 5 minutes or press any other button to exit the alarm sound directly. The alarm will sound again at the same time of the next day until the alarm function gets deactivated. Maximum and minimum values In normal display mode, press the "MEM" button to view the temperature, humidity and CO

concentration data in the followingEN5 order: maximum recorded values (MAX icon is displayed) → minimum recorded values (MIN icon is displayed) → currently measured values (no icon is displayed). Press and hold the "MEM" button for 2 seconds while viewing the maximum or minimum values to clear the recorded MIN/MAX data and start recording again. The maximum and minimum records will be automatically cleared and re-recorded daily at 0:00. Temperature display In normal display mode, press the "DOWN" button to change between °C (Celsius) or °F (Fahrenheit) as temperature unit.

concentration alarm Press the "ALARM CO2" button to activate or deactivate the CO

alarm function. Press and hold the "ALARM CO2" button for 2 seconds to enter the

concentration alarm setting and the CO

concentration value flashes. Press the "UP" or the "DOWN" button to set the desired alarm value. Press the "ALARM CO2" button to confirm and exit the setting and to return to the normal display mode. Notes: You can also save the setting and exit the setting mode any time by not pressing any button for 30 seconds. Press and hold the "UP" or the "DOWN" button for more than 2 seconds to speed up the setting process. Air quality and ventilation recommendation on the basis of CO

concentration in the air Your CO

monitor measures and displays the CO

in PPM with colorEN6 ventilation recommendations. In normal display mode, press and hold the "DOWN" button for 2 seconds and the air quality icon parameters flashes. Press the "UP" or the "DOWN" button to adjust the parameter of the different colored air quality icons. Press the "SET" button to confirm your changes in the following order: EXCELLENT→ GOOD→ MEDIUM→ POOR→ POOR flashing→ confirm and exit the setting mode and return to normal display mode. EXCELLENT：400~（500，600 as options), the default value is 600 GOOD to EXCELLENT+1~（700，800，900，1000 as options), the default value is 1000 MEDIUM to GOOD +1~（1100，1200，1300，1400，1500 as options), the default value is 1500 POOR to MEDIUM+1~（1600，1700，1800，1900，2000 as options), the default value is 2000 POOR flashing：POOR+1and above Notes: You can also save the setting and exit the setting mode any time by not pressing any button for 30 seconds. The setting of the air quality icon parameters is stored in the internal EEPROM of the chip and will not be lost due to power loss. During CO

detection, avoid product vibration and direct blowing of the sensor by strong winds, which may cause deviation of the carbon dioxide detection value. When the CO

concentration reaches MEDIUM or worse, the ventilation recommendation icon will be displayed to remind of the need to open the window for ventilation. When the CO

concentration is greater than 2000PPM, the screen will display to remind users to pay attention because of high CO 2EN7 levels.

sensor This monitor is factory calibrated to a 400 PPM CO

standard concentration. Due to transportation, vibration, aging and other reasons, the CO

sensor may get a zero drift and the detection accuracy may be reduced. In order to restore the accuracy of the sensor, the automatic or manual baseline calibration can be used to correct the drift. Caution: Do not calibrate the monitor in an environment of unknown CO

concentration. Automatic baseline calibration Your monitor is equipped with a smart chip so that it will automatically calibrate itself to reduce the drift of the CO

sensor for long time usage, starting after a minimum of 2 days. It will calibrate itself automatically at the minimum CO

reading detected during 7 days of continuous monitoring.EN8 Notes: Make sure the place you put your monitor at is well ventilated (with a

level near 400 PPM) for at least an hour or so everyday, or you move the monitor to such a well ventilated room for an hour or so everyday to perform the automatic baseline calibration. Automatic baseline calibration function is suitable for office, home and other good ventilation environments. Manual calibration of the CO

sensor It is recommended to undergo manual calibration performed by a qualified laboratory every 12 months.

monitor in a 400 PPM calibration chamber or a room with as close to 400 PPM as possible.

• In normal display mode, press and hold the "UP" button for 2 seconds to enter manual baseline calibration preparation mode. At this time, you can press the "SET" button to confirm the entry, or press the "UP" button or do not press any button for 30 seconds to exit manual baseline calibration preparation mode.

• The operation time of manual baseline calibration mode is 20 minutes. During the operation, you can press "UP" to exit the calibration in advance. Backlight Touch the “SNOOZE/LIGHT” touch field to change the backlight level. Four levels (high - medium - low - off) of backlight brightness are selectable. Low battery indicator and battery loading The battery indicator " " displays the remaining charge of the built-in lithium battery. When the built-in lithium battery voltage is low, there will be a low battery indicator " " flashing on the screen At theEN9 same time, the product will turn off the backlight function, carbon dioxide detection function, etc. to ensure the continuous operation of the time display function, until the battery is charged up again. In the process of lithium battery charging, the battery indicator " " is displayed filling up. The battery symbol is hidden once the battery is fully charged. Troubleshooting No display or functions Check if the USB cable is properly connected to a power source. Response time Ensure the air flow channels at the back of the monitor are not blocked or covered.

reading shows “Err” The CO

sensor is not working properly. Push the power switch " " to “OFF” and wait for 10 seconds before pushing it back to “ON” again. Care and maintenance Place your monitor on a stable surface, away from sources of direct sunlight or excessive heat or moisture. Clean your monitor with a soft cloth moistened only with mild soap and water. Stronger agents such as Benzine, thinner or similar materials can damage the surface of the item. Make sure the monitor is unplugged before cleaning. Do not open the back case or tamper with any components of this monitor. Do not plug in any other USB cables with incorrect specifications or voltage.EN10

levels and guidelines Below are some CO

reference levels in general: 400~600 ppm Background (normal) outdoor air level. 600~1,000 ppm Typical level for occupied spaces with good air exchange. 1,000 ~1,500 ppm Start ventilation of the room. 1,500~2,000 ppm Level associated with complaints of drowsiness and poor air. Ventilation recommended! 2,000~5,000 ppm Level associated with headaches, sleepiness, and stagnant, stale, stuffy air. Poor concentration, loss of attention, increased heart rate and slight nausea may also be present.
