Grounding or Polarization - The precautions should be taken so that the grounding or polarization means of an equipment is not deleated. 12. Power-Cord Protection - Power-supply cords should be routed so that they are not likely to be walked on or pinched by items placed upon or against them, paying particular attention to cords at plugs, convenience receptacles, and the point where they exit from the equipment. 1 3. Cleaning - The equipment should be cleaned only as recommended by the manufacturer. 1 4. Power Lines - An outdoor antenna should be located away from power lines. 1 5. Outdoor Antenna Grounding - ll an outside antenna is connected to the receiver, be sure the antenna system isgrounded soas to provide some protection against voltage surges and built up static charges. Section 81 0 ol the National Electrical Code, ANSI/NFPA No. 70- l981 , provides information with respect to proper grounding of the mast and supporting structure, grounding ol the lead-in wire to an antenna discharge unit, size of grounding conductors, location of antenna-discharge unit, connection to grounding electrodes, and requirements lor the grounding electrode.

TURNTABLE PLACEMENT
1. Before attempting to use your turntable, read this Manual 6. Avoid locating the turntable in the vicinity of other electrical equipment such as television receivers. These generate signals which can cause hum or noise.
3. Handle the equipment carefully-avoid subjecting it to
sudden shocks such as a slamming of a door. 4. Keep the unit out of the direct sunlight, in a place relatively free of dust and humidity. 5. Provide about 1O centimeters at the rear of the unit to
carefully and keep for future reference. 2. Locate the turntable on a firm, level surface.
7. Howling during play
permit the dust cover to be raised without jarring the
turntable.
is often caused by incorrect speaker placement. lf the speakers are too close to the turntable, the stylus will pick up vibrations. Avoid placing the unit on a speaker cabinet. 8. When interconnecting the turntable and amplifier, place the turntable on the side of the amplifier away from the amplifier's transformer, to avoid noise pick-up.

TURNTABLE SET-UP
A. PLATTER While setting up or dismantling the turntable, make sure it is not connected either to the amplifier or to the power source. 1. Remove all protective wrappers and the spindle protector, and dust the Platter and the rest of the turntable thoroughly with a soft, clean, dry cloth. 2. After confirming that the Reject Plate is as shown in the illustration, align the center of the Platter with the Spindle and carefully lower into place. 3. Place the Rubber Mat on the Platter, the grooved side upwards.
Note:
o o o
Operating the motor without the Platter
in place can
damage the motor and should therefore be avoided.
Akai recommends that the dust cover be re-attached after completing the turntable set-up on this page and
the adjustments on page 5.
There are two depressions inside the cabinet for easy
placement and removal of the Platter.

shaft. The range of adjustment is from 0 to 2'5 grams. For AP-D21OC only: The recommended stylus pressure for the
cartridge supplied, PC-85, is 2 grams.
8. Set the ANTISKATING adjuster to the corresponding
stylus pressure.
B. OVERHANG (Not necessary for AP-D21 OC) The distance between the Spindle and the Stylus when the Tone Arm is centered over the Platter is known as the overhang. Different cartridges require different overhang adjustments. For your convenience, the Rubber Mat has indicator grooves at the center to facilitate overhang adjustment. 1. Disconnect the Power Cord. 2. Center the Tone Arm over the Platter.
3. Adjust the cartridge so that the Stylus position is even

NOTES
1. This turntable has been factory adjusted to accommodate the Model PC-85 cartridge, but any Moving Coil (MC) or Moving Magnet (MM) type of cartridge can be used. Adjustments should be made as outlined in this
Manual.
5. The life of the Stylus is much shorter than that of the
turntable. lf the Stylus becomes worn, bent, or otherwise damaged, it will damage the surface of the record. Replace such a Stylus immediately and avoid playing scratched or damaged records. 6. Always avoid touching the surface of the record with the fingers as this will leave marks. Clean the surface of the record with Akai Cleaning Kit CK-200. Make sure that the surface of the record is completely dry before playing
it.
2. 4-CHANNEL STEREO: The turntable can also be used
for 4-channel stereo operation.
For SQ or Regular Matrix 4-channel operation, the unit must be used with a 4-channel cartridge and Stylus. For CD-4 System 4-channel, replace the existing cartridge with a Stylus for CD-4 use. This is all that is needed to provide CD-4 System 4-channel operation. After accom-
