b) Cleaning：
Clean the two long shafts, the bearing, rotary ball and inside of clamping ring with clean
soft dry cloth or paper.
c) Installing the trackball
Put the rotary ball back in the trackball mechanism and put the clamping ring back in (with
the bulge direction of 15 ° deviated from the horizontal line), turn the ring clockwise until the
bulges are flush with the top cover, and the ring clicks and locks, which means the ring is
secured. See figure below.
4. Clean Control Panel
Tools: dry soft cloth, soapy water
Method:
Use dry soft cloth to clean the surface of control panel (including keystrokes, encoders and
sliders). If the control panel is dirty, moisten the soft cloth with a little mild soapy water and wipe
off any stains. Use another dry soft cloth to remove any moisture and allow all hard surfaces to
completely air-dry. If it is difficult to clean the control panel, disassemble the encoder caps first
and then use mild soapy water to clean it.
Keyboard on the control panel should be cleaned periodically; otherwise, keys maybe
blocked by dirt and buzzer dings, keys don’t work.
