 Instructions for Use:

 Connect the bubble stone with the exhaust hole and put it into the water body that needs oxygenation, the solar cell is facing the sunlight, there is no shade between the solar cell and the sunlight, toggle the switch to ON to turn on, the oxygenation pump will start working. When the sunlight is strong, the solar cell can charge the extra power into the internal battery to store it, and then the battery will supply power when there is no sunlight to make the oxygen boosting pump work, this product can also charge the battery through USB 5V 1A power supply.

 Note:

 1. This product is an electronic product, the whole machine can not be placed in water, the inflow hole can not be blocked.

 2. The product needs to activate the circuit after replacing the battery in order to use normally; the activation method will be solar cell placed in the sunlight for 5 seconds, or USB charging port input 5V voltage for 5 seconds.

 3. This product is a solar product, the charging speed is related to the strength of sunlight, regular cleaning of solar cells on the dirt can improve the charging efficiency.
