Warning
2.1
Touch operation
Incorrect / phantom operation:
Incorrect operation of the touch screen may result in accidental functions and errors. The device
will then be unable to execute functions, may execute them incorrectly or in a way not intended.
- Do not realise safety-relevant functions via the touch screen
- Avoid accidental multi-touches
- Do not touch the touch screen across a large area
- Use a touch pen only for the capacitive touch screen
- Before operating the device, thoroughly acquaint yourself with the multi-touch functions of
the operating system and the application
- Switch off the device for cleaning and maintenance
Conductive liquids on the touch screen can result in incorrect or phantom operations. This applies
in particular to salt water.
- Avoid contamination of the touch screen surface with salt water
Protect the device against rain, snow and splashes, since excessive amounts of standing or
running water will disrupt operation and may cause erratic cursor movement.
This protection can be achieved by using a canopy or some other protective roof-type
construction. Offshore, strong winds, saltwater and rain will have to also be taken into
consideration.
Touch screen damage:
Only touch the touch screen with your finger or a suitable pen.
- Do not touch the screen with pointed or sharp instruments as this may damage the touch
screen, substantially reduce its service life or result in total black-out
Foil membrane blistering / air-pockets:
Extreme ambient conditions (high humidity, temperature) may, in rare cases, result in blistering
or air-pockets underneath the foil touch screen. This does not impede functionality and is a purely
optical phenomenon.
