Roland SRA-60 User Manual

Cleaning The Filters
This unit is equipped with a fanned cooling system. This
system includes a filter which is designed to trap dust and dirt
before it reaches the interior. You must routinely clean this
filter, since the cooling ability of the system can drop signifi-
cantly should the filter’s pores become clogged.
How to clean the filter:
1 Turn OFF the unit’s power, and pull out its plug from
the AC outlet.
2 Use a Philips screwdriver to loosen the 4 screws
holding the filter cover in place. Remove the filter
cover.
* Remove only the specified screws. @
3 Take out the filter, and clean or wash it. (If washed
using soap and water, make sure it has been dried
thoroughly before putting it in the unit.)
4 Replace the filter and fasten the cover in place.
* Never use benzene, thinner, or alcohol-based products for clean-
ing the filter, since discoloration or warping could result.
* Never mount the filter in the unit while it is still wet or damp.
* While you have the filter removed, make sure nothing (dust,
foreign objects) gets into the unit.
* Handle the screws carefully so you don’t lose them.
* Should you require replacements for the filter, make your request
to the nearest Roland Service Station (a list can be found on page
15).

e Always pick a place for the unit that is well ventilated, and
easily allows any heat to dissipate. In particular, you must
make sure there will be nothing interfering with the air
flow around the front and rear of the unit.
e When stacking the unit in a rack along with numerous
other devices, allow a space of at least 1 U in size to be left
unoccupied between every four units. At such unoccu-
pied spaces, you should then install a hole-less blank
panel.
e¢ When mounting the unit in a rack stacked together with
numerous other devices, make sure to provide sufficient
ventilation for the rack, since warm air can tend to
accumulate within it. Make whatever provisions are
necessary so as to avoid having warm air that has been
expelled be drawn back in again. In particular, if the rear
of the rack cannot be opened, you will need to provide
some means for expelling the hot air that accumulates at
the top-rear of the rack; by putting in either a ventilation
port or an exhaust fan.
e Avoid mounting the unit in a rack which is tightly closed.
Such racks inhibit proper ventilation, and cause warm air
to be trapped inside. As a result, no real cooling can take
place, since the same warm air will be repeatedly circu-
lated through the unit.
e Ifthe unit is mounted ina hard case, take off both the front
and rear covers, and make sure the air flow at front and
rear is not obstructed.
e Ifthe Protection indicator lights as a result of the heat sink
being excessively hot, you will need to take measures to
assure that the unit will be sufficiently cooled. Check over
your setup and determine what the problem could be with
the way you have the unit placed, especially if in a rack.
Refer to the above precautions, and setup the unit appro-
priately.
