• Safety Precaution (This "Safety Precaution" is applied only inU.S.A.)1. Before servicing,unplug the power cordto prevent an electric shock.2. When replacing pads, use only maanufaacturer's recomended components for safety.3. Check the COnditionof the power cord. Replace if wear or damage is evident.4. After servicing, be sure to restore the lead dress,insulationbarriers, insulation papers, shields,etc.5. Before returning the serviced equipment to the customer,be sure to make the following insulationresistancetest to prevent the customer from

being exposed to a shock hazard.

• INSULATION RESISTANCE TEST1. Unplugthe power cord and short the two prongs of the plug with a jumper wire.2. Turn on the power switch.3. Measure the resistance value with ohmmeter between the jumpered AC plug and each exposed metal cabinet pad, such as screwheads antenna,

control shafts, handle brakets, etc. Equipmentwith antenna terminals should read between 3 MQ and 5.2 MQ to all exposed pads. (Fig. A)Equipment without antenna terminalsshould read approximately infinityto all exposed pads. (Fig. B)

Note: Some exposed pads may be isolated from the chassis by design. These will read infinity.

Antenna Jterminal _

(Fig. A)

Resistance = 3 MQ - 5.2 M_

Ohmmeter

(Fig. B)

Resistance = Approx. o_

4. If the measurement is outside the specified limits, there is a possibilityof a shock hazard. The equipment should be repaired and rechecked beforeit is returned to the customer.

• Preparation of the cartridge D

[] Attach a cartridge (not included).Follow the cartridge's instructions to correctly attach Stto the headshell,

• Use the included shell weight "_ when using a light cartridge (3.5

to 6.5 grams).• Usethe stylusweight -2to increasestyluspressure( ,,_page 6).

Leave it oftuntil stylus pressurehasbeen adjusted.

[] Adjust the overhang.Fit the included overhang gauge to the head shell. Adjust the over-hang and facing of the cartridge and tighten the screws.• Line the point of the stylus up with the end of the gauge,• The cartridge should be parallel on the shell head.

• Putting the player together

Put the player together in the following order.• Do not connect the AC power cord until set up is complete.• Leave the dust cover off until set up and adjustments are complete.

ill Fit the turntable ® and turntable mat @.Putthe turntable on the center spindleand then Jaythe mat on top.

• Be very careful when putting the turntable on the main unit.The magnet on the bottom of the turntable is finely adjusted andsharp contact can cause it to move and lead to poor operation.Ensure the magnet remains free from dust and iron particles.

• Do not adjust the screws attaching the magnet to the turntable.The rated performance of the unit cannot be guaranteed if themagnet is moved.

[] Attach the head shell @.Fit thehead shellinto thetonearm,keep it horizontalandtightenthe lockingnut.

[_"] Attach the balance weight @ to the rear of the tonearm.If thecartridge weighsbetween 10and 13 grams, attachthe in-cluded auxiliaryweight_) tothe main balanceweight.

• Maintenance

I Care of the parts I

To clean this unit, wipe with a soft, dry cloth.If the surfaces are extremely dirty, usea soft cloth dipped ina soap-and-water solution or a weak detergent solution.• Never use alcohol, paint thinner, or benzine to clean this unit.• Before using chemically impregnated cloth, read the instructions that

came with the cloth carefully.

Do not wipe the dust cover while playing a record.This can cause static electricity. This staticcan cause the tone arm to beattracted towards the cover.

Thoroughly clean dust off the stylus and record.• Use a softbrush to clean the stylus.Brushfrom the base to the tip. []• Use a good quality record cleaner to keep your records clean.

Wipe the head shell terminals occasionally []Use a soft cloth. Turn the amplifier off before fitting or removing thehead shell.

• Damage to your speakers can occur if the head shell is moved whilethe volume is turned up.

• Leave the stylus cover on while handling the head shell to preventdamaging the stylus.

Oiling the center spindle. []Apply2 or 3 dropsevery 2000 hoursof operation. Use SFW0O10 oil (notincluded).

Moving the unit ]

Repackage the unit in the packaging it came in.If you no longer have the packaging, do the following:• Return the tone arm to the arm rest and tape it in place.• Remove the balance weight and head shell from the tone arm and

carefully wrap them,• Take off the turntable and turntable mat and carefully wrap them.• Carefully wrap the main unit ina blanket or paper.

• Product service

Do not attempt to remove the cover(s) or repair the unit yourself.Refer servicing to quaIified personnel only.
