Maintenance and Servicing
Maintenance interval
To maintain maximum performance and to protect your invest-
ment, it is essential that your product is serviced in accordance
to the correct maintenance interval.
Every 5000 hours we recommend you to have maintenance
on your product. This operation involves, among other things,
cleaning of connectors, adjustments of DC voltage and idling
current(class A area). See page 4.
Servicing
Refer all servicing to qualifi ed personnel. To reduce the risk
of electric shock, do not perform any servicing other than
that contained in the user manual unless you are qualifi ed
to do so. Servicing is required when the product has been
damaged in any way, such as the product has been exposed
to rain or moisture, does not operate normally or has been
dropped.
Do not remove any cover
There are areas with high voltages inside. To reduce the risk of
electric shock, do not remove any cover if the AC powercord is
connected. The cover should be removed by qualifi ed person-
nel only. No user serviceable parts inside.
Cleaning
When the product needs a cleaning, you can blow off dust
from the amplifi er with a blower or clean with a rag etc. Don’t
use solvents such as alcohol or other fl uids with very strong
volatility and fl ammability for cleaning the apperatus body.
Fuse
To prevent a fi re, make sure to use fuses with specifi ed
standard(current, voltage, type). Do not use a different fuse
or short circuit the fuse holder. Before replacing the fuse, turn
OFF the product and disconnect the powercord.
