This document outlines the operation and maintenance of the Pioneer Multi-Play Compact Disc Player models PD-M502, PD-M552, PD-M602, and PD-M702. It covers essential setup, basic playback functions, advanced programming, and troubleshooting to ensure optimal performance and longevity of the device.
The CD player is designed for multi-disc playback, utilizing a 6-disc magazine. This allows users to load up to six 12 cm (5-inch) discs for continuous listening without manual disc changes. The magazine features a window to check which disc is currently loaded, even during playback. For 8-cm (3-inch) CDs, a special Multi-Play Magazine (JD-M108, JD-M308), sold separately, is required. It is crucial not to load 8-cm discs or their adaptors into the standard 12-cm magazine, as this can cause serious damage to the player. When inserting discs into the magazine, always ensure the label side is facing downward for proper playback. Objects other than discs, such as song cards or explanations, should never be inserted into the disc trays. Users should also avoid touching the playing surface of discs with their hands or fingers.
Setup and Connections:
Before operating the player, it's important to confirm the supplied accessories, which typically include a 6-compact disc magazine, an output cord, and a control cord (for specific models). For models other than PD-M502, two AAA/R03 dry cell batteries are provided for the remote control unit.
Connecting the player involves several steps:
- Audio Output: Connect the OUTPUT jacks of the CD player to the input jacks (CD or AUX) of a stereo amplifier. Ensure white plugs connect to left (L) jacks and red plugs to right (R) jacks. It is critical not to connect the unit to the amplifier's PHONO jacks, as this will result in distorted sound.
- Power Supply: Connect the power cord to a household AC wall outlet or an AC outlet on the amplifier. Always ensure plugs are fully inserted.
- System Remote Control (for compatible Pioneer amplifiers): If using a Pioneer stereo amplifier with the "R" mark, connect the CONTROL IN jack on the CD player's rear panel to the CONTROL OUT jack of the amplifier. This enables control of the CD player using the amplifier's remote control unit. The control cord is supplied with the CD player.
- CD-Deck Synchro Function: For Pioneer cassette decks with CD-Deck synchro, connect the CD-DECK SYNCHRO jacks of both devices. This allows for synchronized recording between the player and deck. The CD-DECK SYNCHRO cord is not supplied with the CD player.
Remote Control Operation (Except for PD-M502):
The remote control unit operates by pointing its infrared signal transmitter at the player's remote control receiver (REMOTE SENSOR) on the front panel. It has an effective range of about 7 meters (23 feet) and an operational angle of up to 30 degrees from the remote sensor. If the sensor window receives strong light (e.g., sunlight or fluorescent light), control may be impaired. For the PD-M502, the remote control unit accompanying the amplifier should be used.
Basic Playback:
- Power On: Turn on the power to the player.
- Insert Magazine: Insert a loaded magazine into the slot until a click is heard. If the power is off (standby mode), inserting a magazine automatically turns on the power (Automatic Power On function).
- Start Playback: Press the PLAY (►) button to begin playback.
- Pause: Press the PAUSE (II) button to temporarily stop playback. Pressing it again or the PLAY (►) button resumes playback.

Maintenance:
- Location: Install the player in a well-ventilated area, away from direct sunlight, high temperatures (radiators, stoves, amplifiers), humidity, or dust. Avoid placing it on unstable surfaces.
- Cleaning: Clean the player and magazine with a soft, dry cloth. For stubborn dirt, use a soft cloth dampened with a mild detergent solution (1 part detergent to 5-6 parts water), then wipe dry. Never use furniture wax, benzine, thinner, or other volatile liquids, as they can corrode the cabinet.
- Disc Handling: Always keep discs clean by wiping gently from the inner edge to the outer periphery with a soft cloth. For very dirty discs, use a water-dampened cloth, then dry. Never use record cleaning sprays, anti-static agents, benzene, thinner, or other volatile solvents. Hold discs by the edges or one edge and the center hole; avoid touching the signal surfaces. Do not affix gummed labels or tape. Do not use damaged (cracked or warped) discs.
- Storing Discs: Store discs vertically in their cases, away from high heat, humidity, or extremely low temperatures to prevent warping.
- CD Lens Cleaner: The pickup lens should not normally get dirty, but if malfunction occurs due to soiling, consult a PIONEER authorized service center. Commercial CD lens cleaners are available, but use with care to avoid damage.
- Condensation: If the unit is moved from a cold to a warm room, or if room temperature rises sharply, condensation may form inside, affecting performance. Allow the unit to stand for about an hour or raise the room temperature gradually.
- Power Cord: Handle the power cord by the plug. Do not pull the cord, touch it with wet hands, place objects on it, or pinch it. Check the cord periodically for damage.
- Remote Control Batteries: Remove batteries if the remote control unit will not be used for an extended period (one month or more) to prevent leakage. If leakage occurs, clean the compartment and replace batteries. Ensure correct polarity when inserting batteries. Never mix new and used batteries or different brands.
Troubleshooting:
The manual provides a troubleshooting guide for common issues:
- Magazine not expelled: Power plug disconnected, or EJECT button not pressed.
- Playback stops immediately/pauses: Disc loaded upside down, smudges on disc, player in pause mode.
- No sound: Output cords connected incorrectly/loosely, incorrect amplifier operation, dirty pin plugs/amplifier terminals.
- Distorted sound/noise: Dirty pin plugs/amplifier terminals, interference from TV, incorrect connections.
- Loud noise/play stops with certain discs: Badly scratched/warped disc, extremely dirty disc.
- TV picture fluctuation/FM noise: Interference from CD player.
- Remote control not functioning: Dead batteries, too far from player, wrong angle, obstruction.
For abnormal functioning due to lightning, static electricity, or other external interference, turn the power off and on again, or unplug and replug the AC power cord. If issues persist after these checks, contact a PIONEER authorized service center or dealer.
