previously stored rotation speed will be appearing.
5) The highest rotation speed for this stirrer is 100 grade, meaning the △ button can be
pressed for 100 times to reach the highest speed. But if the △ or ▽ button is long
pressed or held, the rotation speed can be changed much more quickly.
4. Notes:
1) If powered by batteries, please carefully cover on the white rubber cap of the DV power
outlet.
2) If the bottom of container is rough, the stirrer will be shaking when stirring or couldn’t stir
properly. So users should replace it with a qualified container.
3) When using batteries to power on, if the power of battery is lower than 5V, the red
indicator under the panel will be lighted, indicating that the stored rotation speed will
become slower. So it’s time for users to replace new batteries. However the speed can
also be increased when pressing the △ button. If user doesn’t really care the accuracy
of the stored rotation speed, the stirrer can still be used even if the red indicator is
flickering until power is completely consumed.
4) In the situation of zero rotation speed, please don’t long press the RPM button,
otherwise the stored speed will be set to zero—press RPM button, if the green light
doesn’t flicker, it means rotation speed is zero — under that situation, users only need to
press △ button and reset it.
5) This stirrer comes with B835 and B628 stir bars (one for each), which can meet most
common requirements. If users need other kinds of stir bars, please buy accordingly.
