3-3. About the Data Backup Capacitor
A large capacitor is installed on the CA-45/CA-57 board in
order to backup the memory storing the setup data and the
real time clock in the MKS-8010/8010A machine.
Leave the main power of the MKS-8010/8010A turned on
for an hour or longer in order to charge this capacitor. The
data is backed up for about one week when the capacitor is
fully charged under normal operating temperature.

3-2-2. Cleaning
Front panel
The filter on the rear of the front panel of the MKS-8010/
8010A can easily accumulate dust. Be sure to remove dust
by cleaning it about once in two months.
1. Remove the front panel. (Refer to Section 2-1.)
2. Remove the dust accumulated on the filter with a
vacuum cleaner.
n
Cleaning the filter by washing in water is recommend-
ed when there is a heavy accumulation of dust.
Be sure to dry the filter completely after it has been
washed.
Fan
The inside of the MKS-8010/8010A is cooled by a fan
(side on the rear).
If dust has accumulated in the intake of the fan, air is
prevented from flowing smoothly and this may result in a
temperature rise inside the machine. This may have an
adverse effect on performance and life of the machine.
Cleaning of the fan every month is recommended.
Contact your local Sony Sales Office/Service Center for
information cleaning the fan.
