2-2-1. Cleaning

1. Fan
The inside of the CCP-9000-C is cooled by a fan 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.

2-3. About the Data Backup Capacitor
A large capacitor is installed on the CA-52 board in order
to backup the memory storing the setup data and the real
time clock in the MKS-9011/9012 machine.
Leave the main power of the MKS-9011/9012 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.
Tighten the lock.
