2. How to Use Preset Height
At any height (unavailable under the reset and error status), keys 1/2/3 may be
used to quickly reach the preset height. If the current height has reached such
preset height, no acons will be performed.
3. How to Change the Height
• Use the “Up” key to li the display. The li will automacally stop upon reaching
the height limit. Please note, the “Up” key is a “click to act” key, i.e., upon
releasing the key the li will not immediately stop. Instead, it will slow down for
a short distance then stop.
• Use the “Down” key to lower the display. The li will automacally stop upon
reaching the height limit. Please note, the “Down” key is a “click to act” key, i.e.,
upon releasing the key the li will not immediately stop. Instead, it will slow
down for a short distance then stop.
