Cleaning for Front Ventilation
Use vacuum cleaner to remove any dust or threads accumulation
away from both the ventilation holes on front cover and ventilation grids on
chassis exposed after removal of the front cover.
Replacing Front Cover

the front cover in position. Please make sure the all hooks on front cover is
well positioned into chassis. Please remember to check that the power switch is
at “Off” position before power and signal connection.
Accessing Side Ventilation Grids
The operation to further clean the side ventilation grids requires much
more highly technical maneuver. Therefore careful attentions must be taken
throughout the further cleaning operations below. When the main unit is
opened, there must be no liquid spill,
no electro-conductive material, no
electric charged device come into the
area of the main unit. Please also note
that not to touch any component or
cable inside.
Please first disconnect every
cable from the main unit and prepare
enough space in front of the PB
system and lay a piece of clean soft
clothe of appropriate size there to
prevent damage. With the back cable cover opened, push in the circled spring
button in the above picture on both sides of chassis and raise the rear edge of
the top cover. Apply some mild maneuver if there is already a pole display
mounted.
