Maintenance 35
General Cleanness
General Cleanness of the Maxpad™ must be accomplished with a paper towel or
highly smooth fabric, slightly humid. Never use chemical products or abrasives be-
cause they may damage the paint or the integrated electronic components.
In order to facilitate the removal of grease from the frontal touch screen glass use
alcohol of high concentration (above 92°). Apply the alcohol in small quantities using a
paper towel or fabric of high smoothness slightly humid.
Cleanness of optical sensors
Each and every Apek Maxpad™ has four optical sensors of high precision,
placed internally in the four vertices of the LCD monitor.
This sensors are micro cameras with infra red vision technology, that allow Maxpad
todetectuptosixpointsoftouchonthescreen,oeringanadvancedrecognitionof
multi touch gestures.
For the touch screen to be kept in its maximum precision and don´t present blind
points (areas where the screen does not answer to the touch), it is recommended
that the Optical Sensors and all the IR (infra red) illumination perimeter of the screen
should be cleaned regularly, each 30 days or always when a great amount of dust is
detected on the components.
It is recommended that the cleanness of these sensors should be done with
swabs(ex:Cotonetes®)slightlyhumidiedwithalcohol(atleast92°).
For this, it is only necessary to slide the cotton edge of the swabs all around the lat-
eral perimeter of the screen, over a dark wine color plastic piece and over the optical
sensors on the four vertices of the board. Check the detailed illustration.
