3. Maintenance Safety Precautions

Before doing maintenance work

DANGER

Ensure that the power has been shut down, and move after the rotating screen has

come to a full stop.

Ensure disconnecting the power cord from the power outlet first.

Ensure the display unit is well-supported when moving otherwise it’s easy to be tilted

or fallen down.

While doing maintenance work

WARNING

Do not make any object fall into the drum or base to prevent the display system from

breaking down during operation.

Please do “not” use toluene (methyl benzene), thinner, gasoline, or any acidic

dissolvent to clean the screen shield.

Be careful not to scratch the screen shield surface.

Do not touch any components on the PCBs. Hold the PCBs by the edge to protect

the components on the PCBs from being damaged by the electrostatic on the body
through hands.

Do not change default settings or try to adjust any devices inside the base without

the guidance of professional technicians or engineers from DynaScan.
