1) Remove black waterproof rubber cap, plug in adapter. 

2) Place the vessel with medium on work pan, put a stir bar into vessel. Please note that the vessel should be placed on the center of work pan.

3) Press “on/off” button, indicator light in red color.

4) 
Press “ Mode/▵” button to select Counter-clockwise and Clockwise mode or Clockwise mode.

5) Press “ Rev/▿” press to select speed (Totally five speeds). 

6) Press “ Start/Stop” button to start or stop operation.  

B. When the medium was mixed well, press “Start/Stop” button again, the stirrer will stop working, the indicator light turns red.

















A. After choosing stir direction and speed, we can press “Start/Stop” button to have the stirrer start working, the indicator light turns green from red.

7) Press “Timing” to set timer（Timer Range: 30s-99 Minutes 99s）.

Press "TIMING", "10:00" is flashing and a clock icon on the screen,this means

timer is 10 minutes. If you want timer above 10 minutes, press "MODEL/▵" shortly can increase 1s each time, and press "MODEL/▵" long time can increase 10s each time;

If timer exceed the time you need, press "REV/▿" shortly can decrease 1s each time, and press "REV/▿" for long time can decrease 10s each time.

Press "TIMING" again, quit timer setting.

There are 2 functions of timing:

A. When the stirrer is not working ( indicator light in red), it will start to stir when time is up.

B. When the stirrer is working ( indicator light in green), it will stop stirring when time is up.
