60° SR4023
Remote controller
Approx. 5 m
Caution:
• Do not allow direct sunlight, an inverter fluorescent
light or other strong source of light to shine onto
the player’s infrared receptor window. Otherwise,
the operation of the remote controller may be
disabled.
• Bear in mind that operating the remote controller
may cause other devices operatedby infrared rays
to be operated by mistake.
• The remote controller cannot be operated if the
space between the controller and the player’s
infrared receptor window is obstructed.
• Do not place any objects on top of the remote
controller.
Doing so may cause one or more buttons to be
held down which will cause the batteries to run
down.
LOADING BATTERIES
Before using the remote controller for the first time,
load the batteries in the remote controller. The
batteries provided are used to verify the operations
of the remote controller only.
1. Remove the battery cover.
2. Load the two new size “AAA” batteries inside
the battery compartment while taking care to
align their polarities correctly with the polarity
markings ( with ( and with ).
3. Close the battery cover until it clicks shut.
CAUTIONS ON BATTERIES
• Use “AAA” type batteries in this remote controller.
• We recommend that you use alkali batteries.
• If the remote controller does not operate from
close to the unit, replace the batteries with new
ones, even if less then a year has passed.
• The included battery is only for verifying operation.
Replace it with a new battery as soon as possible.
• When inserting the batteries, be careful to do so in
the proper direction, following the + and - marks in
the remote controller’s battery compartment.
• To prevent damage or battery fluid leakage:
- Do not use a new battery with an old one.
- Do not use two different types of batteries.
- Do not short-circuit, disassemble, heat or
dispose of batteries in flames.
• Removethe batteries whennotplanning tousethe
remote controller for a long period of time.
• If the batteries should leak, carefully wipe off the
fluid from the inside of the battery compartment,
then insert new batteries.

(3/8inch)
1. Strip away approx. 10 mm (3/8inch) of wire
insulation.
2. Twist the bared wire ends tight, to prevent short
circuits.
3.
Loosen the knob by turning it counterclockwise.
4. Insert the bare part of the wire into the hole in
side of each terminal.
5. Tighten the knob by turning it clockwise to
secure the wire.
Caution:
• Be sure to use speakers with the specified impedance
as shown on the rear panel of this unit.
• To prevent damage to circuitry, do not let the bare
speaker wires touch each other and do not let them
touch any metal part of this unit.
• Do not touch the speaker terminals when the power
is on. It may cause you to receive an electric shocks.
• Do not connect more than one speaker cable to one
speaker terminal. Doing so may damage this unit.
Note:
Be sure to connect the positive and negative cables for
the speaker properly. If they are miss-connected, the
signal phase will be reversed and the signal quality
will be corrupted.

Connecting the supplied FM antenna
The supplied FM antenna is for indoor use only.
Duringuse,extendtheantennaandmove itinvarious
directions until the clearest signal is received.
Fix it with push pins or similar implements in the
position that will cause the least amount of distortion.
If you experience poor reception quality, an outdoor
antenna may improve the quality.
Connecting the supplied AM loop antenna
The supplied AM loop antenna is for indoor use
only.
Set it in the direction and position it to where you

possible from the unit, televisions, speaker cables,
and power cords.
If you experience poor reception quality, an outdoor
antenna may improve the quality.
1. Press and hold down the lever of theAM antenna
terminal.
2. Insert the bare wire into the antenna terminal.
3. Release the lever.
CONNECTING AN FM OUTDOOR ANTENNA
Notes:
• Keep the antenna away from noise sources (neon
signs, busy roads, etc.).
• Do not put the antenna close to power lines. Keep it
well away from power lines, transformers, etc.
• To avoid the risk of lightning and electrical shock,
grounding is necessary.
CONNECTING AN AM OUTDOOR ANTENNA
An outdoor antenna will be more effective if it is
stretched horizontally above a window or outside.
Notes:
• Do not remove the AM loop antenna.
• To avoid the risk of lightning and electrical shock,
grounding is necessary.
3. Insert the hook at the bottom of the loop part
into the slot at the base part.
4. Place the antenna on stable surface.

You can control other Marantz products through
this unit with the remote control by connecting the
REMOTE CONTROL terminals on each unit.
The signal transmitted from the remote control is
received by the remote sensor on this unit. Then the
signal is sent to the connected device through this
terminal. Therefore you only need to aim the remote
at one unit. Also, if a Marantz power amplifier (some
models excluded) is connected to one of these
terminals, the power amplifier’s, power switch is
synchronized with this unit’s power switch.
Set the REMOTE CONTROL SWITCH on the units,
other than the main unit to EXT.(EXTERNAL) for this
feature.
