Before use

Placement precautions

• Place the unit in a stable location near the audio system that you will use with it.
• Do not install this unit in a location that could become hot. This includes places that are exposed to direct sunlight or near a radiator, heater, stove or other heating equipment. Moreover, do not place it on top of an amplifier or other equipment that generates heat. Doing so could cause discoloration, deformation or malfunction.
  Also avoid locations that are subject to vibrations or exposed to excessive dust, cold or moisture.
• When installing this unit, leave a little space (at least 3 cm or 1") between it and walls and other devices in order to allow good heat dissipation.
  If you put it in a rack, for example, leave at least 5 cm (2") open above it and at least 10 cm (4") open behind it. Failure to provide these gaps could cause heat to build up inside and result in fire.
• You may stack this unit with a PD-501HR, NT-505 or other 501/503/505 series units. However, if heat should cause the protection circuit to be activated and sound output stops suddenly, place this unit on top and with sufficient distance between it and walls and other devices in order to improve heat dissipation.
• Do not place CDs, CD-Rs, cassette tapes, other audio equipment or other items that are susceptible to heat on top of the unit. Doing so could damage these items.
• Do not put cloth on top of the unit or place the unit on top of bedding or thick carpets. Doing so could cause the unit to overheat and damage it. o Do not move the unit during use.
• The voltage supplied to the unit should match the voltage printed on the rear panel. If you are in any doubt regarding this matter, consult an electrician.
• Do not open the body of the unit as this might result in damage to the circuitry or cause electric shock. If a foreign object should get into the unit, contact your dealer.
• When removing the power plug from the wall outlet, always pull directly on the plug; never yank on the cord.

Using the remote control

Precautions for use
Misuse of batteries could cause them to rupture or leak, which might result in fire, injury or the staining of nearby materials. Please carefully read and observe the precautions.

• When using the remote control, point it toward the remote control signal receiver on the main unit from a distance of 5 m (16 ft) or less. Do not place obstructions between the main unit and the remote control.
• The remote control might not work if the remote control signal receiver on the unit is exposed to direct sunlight or bright light. If this occurs, try moving the unit.
• Beware that use of this remote control could cause the unintentional operation of other devices that can be controlled by infrared rays.

Installing batteries
Remove the cover from the back of the remote control and insert two AAA batteries with their / oriented as shown in the case. Replace the cover.

When to replace batteries
If the distance required between the remote and the main unit decreases or if the unit stops responding to the remote buttons, replace both batteries with new ones.
Dispose of the used batteries according to the instructions on them or requirements set by your local municipality.

Precautions when connecting speakers

• Connect the power plugs after all connections have been made.
• Carefully read the manuals of the devices that you are connecting and follow their instructions when making connections.
• When the left and right grounds are shared in a sub woofer with a built-in amplifier, for example, use might not be possible depending on connection conditions.

ATTENTION

• This unit works with speakers that have nominal impedances between 4 Ω and 8 Ω. Use of speakers with impedances of less than 4 Ω, in particular, could cause the protection circuit to activate and sound output to stop. In some cases, damage could even occur to this unit and the speakers.
• This unit's red terminal is positive () and its black terminal is negative (). Generally, the wire of the speaker cable is marked to distinguish it from the wire of the cable. Connect the marked wire to the red terminal and the unmarked wire to the black terminal.
• If the exposed end of a core wire in a speaker cable contacts another cable or terminal, a short could occur.
• Never allow speaker cables to cause a short.
• To prevent hum and noise, avoid bundling the cables together with the AC power cord or other cables.

Connecting speakers

How to connect speakers

1. Remove about one centimeter (1/2") of insulation from the end of the speaker cable and twist the core wires well.
2. Turn the terminal cap counterclockwise to loosen it.
3. Insert the wire into the hole in the terminal post and turn the terminal cap clockwise to securely connect it.
   
   • Connect it so that none of the wire insulation is touching the terminal.
4. Confirm that the cable is fastened securely by gently pulling the cable.

Connecting with banana plugs
You can also make connections using commercially-available banana plugs. First, connect the banana plugs to the speaker cables and then connect the plugs to the terminals.

• Keep the caps tightened when in use.
• Carefully read the instructions for the banana plugs that you are using.

ATTENTION
Notice about the European model
In accordance with European safety regulations, connecting banana plugs to speaker terminals is not allowed on European models. The holes into which banana plugs could be inserted have been covered with black caps.
Connect speakers using bare wires or spade lugs.
If a black cap should become separated from its terminal, return it to its original position.

Troubleshooting

If you experience a problem with the unit, please take a moment to review the following information before requesting service. If it still does not operate correctly, contact the retailer where you purchased the unit.

General

The unit does not turn on

• Check that the power cord is completely plugged into the power outlet. If the outlet is switched, confirm that the switch is in the ON position.
• Connect a different electrical device to the outlet to confirm that it is supplying power.

No sound is output

• Adjust the VOLUME knob. Turn it clockwise (right) to increase the volume
• Use the INPUT SELECTOR knob to select the input that is connected to the source that you want to hear
• Reconfirm the connections with other equipment.

Remote control does not work

• Set the main unit STANDBY/ON switch to ON before using the remote control.
• If the batteries are exhausted, replace both of them with new ones.
• The remote control will not work if there is an obstruction between it and the main unit.
  Point the remote control at the remote control center on the unit from a distance of less than 5 m (16 ft.).

A television set or another device operates in error

• Some televisions that are able to receive signals from wireless remote controls might be operated in error by this unit's remote control.
  If this is the case, turn the other devices off when using this remote control.

Noise occurs

• Place the unit as far away as possible from TVs, microwave ovens and other devices that have strong magnetism.

There is a humming noise

• If a connecting cable is near a power cord, fluorescent light or similar cause of interference, increase the distance between them as much as possible.

There is no sound from one side of the headphones

• Confirm that the headphones plug is inserted completely.

The level meter lights are blinking and no sound is output.

• The and speaker cables might have shorted. Set the STANDBY/ON switch to STANDBY, and check the speaker connections.

Sound output stops suddenly and the level meter lights are blinking.

• The protection circuit might have activated due to high temperature, excessive load or another cause. Set the STANDBY/ ON switch to STANDBY, check the power and speaker connections, and wait several minutes before setting it to ON again. If this unit is becoming hot, increase the amount of space between it and walls and other devices to increase the dissipation of heat.

Automatic power saving caused the unit to enter standby.

• Set the STANDBY/ON switch to STANDBY once and then set it to ON again.
