Location of Position Lock Buttons
Range of motion is adjustable for user comfort and can vary from 30 to 80 degrees of
inclination from the horizon. Thus each user can position the touchscreen to a
comfortable angle, just as a microphone can be repositioned to a suitable height for
each speaker. The comfortable angle is herein referred to as user position. The
position lock guarantees that once a user position is established or locked, the angle
will not degrade from repeated presses on the touchscreen.
The touchscreen is free to move up from the nearly horizontal position to a larger
incremental angle. Grasp the touchscreen with a hand at each side (or just one hand
at either side, as shown after this paragraph) and gently tilt up to a comfortable
position. To activate position lock, slightly reverse the motion until the touchpanel
stops moving. The touchscreen is now set into user position.
NOTE: If the position lock button is held down as the screen is tilted, there are no
audible clicks.
Two-Hand Placement for Tilting a Touchpanel to a Vertical Position
Once in user position, position lock is activated which means the touchscreen can not
be forced to a horizontal position without depressing the position lock button(s). The
touchscreen is still free to tilt up; a new user position is established at each increment
or audible click.
A position lock button needs to be pressed before the touchscreen can be returned to
a more horizontal position. To press the button, slightly position the touchscreen in
the vertical direction with one or two hands, avoiding any horizontal movement. The
position lock button can then be held down and the touchscreen can be tilted to a
more horizontal position.
