Is it possible to start logging or to delete stored data when it is not possible to connect the MOUSE-E-MOTION Universal Data Logger to a PC (e.g. in an animal facility or outdoors)?

Yes. The basic functions start logging, stop logging, delete data and data output can be put into operation via the buttons of the device. (Changing the configuration of the device, however, is only possible with a PC using the MOUSE-E-MOTION Excel add-in.)
