Annex B
Installing batteries.
Remove the top cover of the appliance by removing the six screws on the
side walls.
Install the batteries as shown in the figure, observing the polarity (positive
pole of the battery to the positive terminal on the device board). Positive terminals
are marked with a "+" on the board. The positive pole of batteries is usually also
marked with a "+" sign. Like salt or alkaline batteries, the terminals of lithium-ion
batteries differ in shape: the positive terminal is convex and the negative terminal is
flat. If you are in doubt about the polarity of the battery, use a voltmeter.
Warning!!! Incorrect connection of the batteries may result in damage
to the device.
Two 3.7 volt 18650 lithium-ion batteries with built-in protection (BMS) can
be used to power the device. Do not use other types of batteries!
