- Connection of USB port line
- 7.4V Rechargeable lithium battery/1100mAh (the battery cannot be dismantled at will. Please contact the manufacturer is it needs to dismantle the lithium battery).  
- Work time of the battery: the time for continuous test is longer than 3 hours.  
- Display of remaining energy: three-grid battery electricity display (it needs to charge if one grid of electricity is left. The charging should be made before the battery electricity displays red. This will result in reducing service life and capacity of the battery). The electricity is tested once at the time of power on.

III. Use method
Power on
- Take out the product from the package. After the power key is pressed, product LOGO is displayed and it enters the main page and displays the interface of dust particle number/L or PM2.5 air quality ug/m3 (interface may be changed at functional parameters).  
- Power off: At power-on state of the instrument, press power key  ( )to power off. The instrument will power off automatically if there is no operation within 2 minutes.  

Note:
- When power supply of battery and adapter exists at the same time, the circuit adopts adapter as power supply.  1. When the adapter is disconnected, the circuit adopts battery as power supply.  
- When power adapter is used to provide supply, it is not necessary to pull off the plug of the power adapter. If there is no operation within two minutes, the instrument will power off undoubtedly and automatically. After automatic power off, the adapter charges the lithium battery. The time of charging is two hours.
- The instrument will appear with sleep state if it is not used for a long time and cannot power on. At the moment, adapter may be disconnected to wake up the circuit of power supply. If the electricity display on the top right corner is not three grids of full electricity after powering on, it is necessary to charge the battery of the instrument.

Description of key function
- RUN key: Press the key once and the instrument’s screen displays the sampling time and begins countdown of 50s. The collected data is displayed once every 10s. For the collected data, the data of last collected is correct reference data.

- When Down key is pressed once, the instrument enters historical record →functional parameter setting in proper order. Data may be checked at the bottom of history page. Press ENTER to confirm the state of certain page for specified check of current page in historical record. At the moment, SHIFT key may be used to select hundred place ←tens place← unit place of current page. Press UP () key or DOWN () key to select 001-999 page of current page.

At the page of functional parameters, press ENTER to confirm that functional parameters enter change state. At the moment, use SHIFT to select the item to be changed. Press UP () key or DOWN () key to select the function. Press ENTER to confirm completion after selection. Change of parameter function is completed at the moment. Press BACK key to return to previous interface until to the main interface.

VIII. Considerations
- The device cannot be started if the inlet pipe is covered or blocked.
- The product should be placed at a horizontal, dry environment without direct sunlight for storage.  
- The product should not be placed in an environment with PM2.5 concentration exceeding 999ug/m3. Exposure to air with high concentration of pollution will result in damage of the sensor so that the equipment cannot work normally.
- The product should be placed at an area with slow air circulation when it is used for measurement to prevent interfering with the detection result caused by direct blowing of strong air blowing to the inlet pipe.
- The product is not provided with waterproof function. Don’t splash water or other liquid onto the device. The service hotline should be dialed at once in case of such condition.
- The device should not be used in environment vulnerable to invasion of rain, snow and humid climate. Otherwise, failure may be brought to it.  
- Don't dismantle and repair the product without authorization. This may result in failure of the device. Please dial the service hotline if there is any doubt. Our company will not undertake any responsibility for any loss with respect to unauthorized dismantling.
- The device should be placed at a stable and safety site to avoid dropping off of the device body.
