Roland S-4000D 用户手册

 

This unit performs forced cooling by means of a cooling fan. Give attention to the 
following points.

 

•

 

Never block the cooling-fan intake port or ventilation port in the rear panel. Doing so 
may cause the temperature of the unit’s interior to rise, resulting in malfunction caused 
by heat.

 

•

 

Clean away any buildup of dust in the intake port or ventilation port using a vacuum 
cleaner or the like.

 

●

 

This unit can be installed in a rack. When installing the unit in a rack, to ensure efficient 
cooling, give attention to the following points.

 

•

 

Ensure that the location provides good air flow and ventilation.

 

•

 

Never block the cooling-fan intake port or ventilation port in the rear panel.

 

•

 

Avoid using the S-4000D in sealed-type rack mounts. As this type of rack does not 
permit heated air within the rack to be expelled, the heated air is drawn into the 
S-4000D as a result, thus preventing adequately efficient cooling.

 

•

 

If the rack’s rear panel is not removable, ensure that a ventilation port or exhaust fan is 
provided at the top of the rack’s rear panel to expel any accumulated heat.

 

•

 

If the S-4000D is mounted in a portable rack, remove both the front and rear rack covers 
before use to ensure that the S-4000D’s front and rear panels remain unobstructed.

 

•

 

When installing the unit on a rack, detach the rubber feet from the bottom of the unit.

 

 

●

 

Use due caution when mounting the S-4000D in a rack or other enclosure so you don’t 
get your fingers wedged or pinched.
