work Instruction: boot up the LED displays the remaining battery power, which is displayed in 5 levels. When the battery is low (3.2V), the last LED flashes.

5. Charging method:

mode1: solar panel charging charging duration: 15h

mode2:USB charging (1A charging) charging duration: 5h

charging indication: during charging the LED path is waterfall light-shaped indicating charging, and the 5 LEDs are fully on after being filled.

II. Instructions for use:

  connect the bubble stone with the vent hole and put it import in the water body that needs oxygen enrichment, Sun the battery board is too sunshine, solar cell and Sun light no barrier, press switch oxygen pump is on beginning work, press the switch repeatedly to select different working modes.

Six. Note:

1. This product is an electronic product, oxygen-increasing part device cannot be put in water medium, the diversion hole cannot be blocked.

2. This product is a solar energy product, the charging speed is related to the intensity of sunlight, and the dirt on the solar cell is cleaned regularly to improve the charging efficiency.
