Need help?Do you have a question about the Aiwa XR-MS5 K and is the answer not in the manual?
This document provides a service manual for the Aiwa XR-MS5 and XR-MS6 SIMPLE-2 compact disc stereo systems. It includes detailed information for servicing, technical specifications, and operational features.
The Aiwa XR-MS5 and XR-MS6 are compact disc stereo systems, categorized as CLASS 1 LASER products. They integrate a tuner, amplifier, and CD player into a single unit. The system is designed for audio playback from compact discs, radio reception (FM, MW, LW), and external audio sources via auxiliary inputs. It also supports headphone output and a super woofer output.
The system features a front panel with various controls, including a jog dial for volume/multi-jog functions, tuning up/down buttons, preset buttons, and function selection. It includes a display (FL101) for showing operational status and settings. The remote sensor (IC101 GP1U271X) allows for remote control operation. The CD player supports standard playback functions, including search and play modes, and features a loading mechanism for disc insertion. The tuner allows for FM, MW, and LW band selection. The amplifier provides audio output to speakers, headphones, and a super woofer.
The manual emphasizes strict adherence to safety precautions when servicing the device due to the presence of a laser. Technicians are warned not to approach the laser exit too closely and to observe from a distance of more than 30cm from the surface of the objective lens on the optical pick-up block to avoid exposure to invisible laser radiation. Using controls, adjustments, or procedures other than those specified in the manual may result in hazardous radiation exposure.
When replacing the optical block, technicians must ground their body and workbench to prevent electrostatic discharge from ruining the laser diode. Care must be taken to avoid touching the diode with clothing. After connection, specific solder points must be removed.
The manual provides detailed, step-by-step instructions for disassembling the AZG-X mechanism and placing it in a service position. This includes removing side panels, the top panel, and the front assembly. Specific steps are outlined for disconnecting flexible flat cables (FFC) and connectors. Instructions are also provided for removing the PWB, CD, and PLATE CD RE, emphasizing careful handling of slits and bosses during reassembly. Further steps detail the removal and reassembly of the CD MECHA ASSY, PLT, SLIDER, LVR, ROLLER ASSY, and MOTOR ASSY, with illustrations to guide the process and highlight critical alignment points (e.g., rubber dampers, damper hooks, gear positions, screw bosses, and motor label direction).
A dedicated CD Test Mode is available for diagnostics.
The manual includes detailed adjustment procedures for the tuner and micro-controller sections, covering:
These procedures involve setting specific frequencies, adjusting components (e.g., L951, L942, L801, L901, L902, L904, L905, L907, L101), and verifying output levels, voltages, distortion, and frequency readings at designated test points (TP1, TP2, TP3, TP4, TP8, TP9).
