LCD difficult to read

If the LCD is difficult to read after the appliance has
been switched on, you should check the batteries as
follows:
Turn the measurement-mode switch (fig. 1, pos. 8) to
the position, and switch over to diode testing by
means of the blue function button (fig. 1, pos. 2). The
battery voltage is now displayed. The displayed voltage
should be between 2.8 V and 3.2 V in order to guar-
antee safe operation of the MMD 302. The batteries
should be changed if this value lies below 2.5 V.
