Usage method:

1. Long press the power switch (press 3 seconds) blue light is on, that is, start to oxygenate, this time for long-term oxygenation mode.

2. Press the power switch again (press 1 down) oxygenation mode is switched to intermittent mode, (stop for 2 seconds, oxygenation 8 seconds cycle mode).

3. Charging: when the voltage is insufficient, the blue light turns into red light, and enters the flashing state, that is to say, the voltage is insufficient, please charge in time, charging at the same time can also oxygenate: that is to say, while charging and oxygenating.

This product is AC/DC dual-use oxygen pump, using pure copper movement, high-quality lithium batteries, the cycle life of up to 500 times, with a small size, low noise, large volume of gas, long life, full of electricity can be used continuously for 24 hours.

The internal circuit is controlled by imported microcontroller, featuring constant voltage and constant current charging, overcharge and overdischarge protection, low power alarm, and high safety coefficient.

Widely used in a variety of ornamental fish, aquariums, fish enthusiasts, company fish tanks, family fish breeding fish oxygenation, especially suitable for power outages emergency oxygenation, as well as field fishing, a small amount of aquatic transportation of oxygen function.
