Otherwise, if the battery polarity is reversed it can be damaged and leak and damage the device.
Then insert the batteries with tubes into the battery compartment (ensure correct polarity).
ATTENTION! The device is not designed for rechargeable batteries. Therefore, they must not
be used. Rechargeable batteries can be damaged, leak, and damage the device.
The socket provided for the mains adapter (15V DC) is located on the bottom right of the front part
of the housing (see also 5.7. ‚Interfaces')
WARNING! Danger of electric shock! Observe the SAFETY INSTRUCTIONS at the beginning
of the manual!
Insert the mains adapter in the socket and connect it to the side of the device. The mains adapter can
supply the BOD Direct plus measurement system and the stirring device with power via the supplied
Y-adapter.
We recommend supplying the device with power via the mains adapter in order to ensure a long
battery life.

Switching on and off

If the device is switched off, it can be switched on with the ON/OFF key. If the ‚Auto-off' option is
activated and no keys/keys are pressed for an extended time, the device switches off automatically in
two stages. First the background lighting is switched off and then it switches off completely (if any
measurements are still pending, the device is automatically activated at the given time). The device
can also be switched off manually with the ON/OFF key.

Replacing batteries

Switch off the device with the ON/OFF key. Before it switches off, the next menu item is shown, if
provided. By this time, the device must be supplied with power via the batteries or the mains adapter;
otherwise measurements are lost. Replace the batteries as described under 5.2 ‚Initial commissioning'.
Place the samples back in the rack and then switch on the device so that the heads are recognised
and the measurements in progress are continued.
