Main Features

• Individually designed as the high-quality
Separate Collection Series

• 4 ohm-drive capability with discrete out­put stage circuit

Memory Preservation

This unit does not require memory preservation bat­teries. A built-in memory power back-up system pre­serves the contents of the memory during power fail­ures and even when the unit is unplugged. The unit
must be plugged in order to charge the back-up sys­tem.

WARNING:

TO REDUCE THE RISK OF FIRE OR
ELECTRIC SHOCK, DO NOT
EXPOSE THIS APPLIANCE TO RAIN
OR MOISTURE.

CAUTION:

TO REDUCE THE RISK OF
ELECTRIC SHOCK, DO NOT
REMOVE COVER (OR BACK). NO
USER-SERVICEABLE PARTS INSIDE.
REFER SERVICING TO QUALIFIED
SERVICE PERSONNEL.

• Input selector for six audio sources

• Remote control operable with

-con-

nected ONKYO components

The memory preservation period after the unit has
been unplugged varies depending on climate and
placement of the unit. On the average, memory con­tents are protected over a period of a few weeks af­ter the last time the unit has been unplugged. This
period is shorter when the unit is exposed to a highly
humid climate.

WARNING

RISK OF ELECTRIC SHOCK

DO NOT OPEN

The lightning flash with arrowhead symbol, within
an equilateral triangle, is intended to alert the user
to the presence of uninsulated “dangerous
voltage” within the product’s enclosure that may
be of sufficient magnitude to constitute a risk of

electric shock to persons.
The exclamation point within an equilateral

triangle is intended to alert the user to the
presence of important operating and maintenance
(servicing) instructions in the literature

accompanying the appliance.
