aircraft. The use of pressure washers is not recommended. Sparing use of
warm soapy water is recommended for the painted surfaces.

other fluids may cause discoloration or spots.

8) At the insertion or removal of the power and signal interface connectors,
ensure that the sockets are free from debris and be sure not to damage the

bend the display even momentary. When designing a suitable mounting, it
should be taken into consideration that no bending/twisting forces are applied
to the display from outside. Otherwise the TFT -LCD module or backlight may
be damaged.
