Mounting considerations
When selecting a mounting location for the trackball control unit, keep in mind the fol-
lowing points.
• Select a location where the controls can be easily operated.
• Locate the unit away from heat sources.
• Locate the unit away from places subject to water splash and rain.
• Referring to the outline drawings at the back of this manual, allow room for mainte-
nance and service.
• Select a mounting location considering the length of the cable.
• Do not place items which should not get wet near the display unit.
There is the drain hole on the bottom of this unit. If water enters the unit from the
clearance around the trackball, water is drained from the drain hole.
• A magnetic compass will be affected if the unit is placed too close to the magnetic
compass. Observe the compass safe distances at the front of this manual to prevent
interference to a magnetic compass.
