This document describes the Sony CDX-L350 FM/AM Compact Disc Player, a car audio system designed to provide FM/AM radio reception and CD playback capabilities.

Function Description

The Sony CDX-L350 serves as a comprehensive in-car entertainment system, integrating a CD player, FM/AM tuner, and a power amplifier. Its primary functions include playing audio CDs, receiving FM and AM radio broadcasts, and amplifying audio signals to car speakers. The unit features a detachable front panel for security against theft, a digital clock display, and various sound adjustment options. It also includes a "Best Tuning Memory" (BTM) function for automatically storing strong radio stations and "My Best Sound Position" (MBP) presets for optimizing the sound environment. The "D-BASS" feature enhances low-frequency sound for a more powerful bass experience. The system can be controlled directly from the unit's front panel or via the supplied RM-X115 card remote commander.

Getting Started:

Resetting the unit: Essential after initial installation or car battery replacement. Achieved by pressing the RESET button with a pointed object, which also erases clock settings and some stored contents.
Attaching/Detaching the front panel: The front panel can be attached by aligning and pushing it until it clicks. It can be detached by pressing the RELEASE button and pulling it off, providing security against theft. A caution alarm beeps if the ignition is turned off without removing the front panel.
Setting the clock: The clock uses a 12-hour digital display. It is set by pressing DSPL for 2 seconds, then using the volume +/- buttons to adjust hours and minutes, confirmed by pressing SEL.

Canceling beep sound: Pressing 6 while holding SEL down disables the unit's beep sound.

Maintenance Features

General Precautions:

Temperature: Allow the unit to cool if the car was parked in direct sunlight. Avoid exposing discs to heat/high temperatures.
Moisture condensation: If moisture condensation occurs (e.g., on rainy days), remove the disc and wait for about an hour for it to evaporate.
Sound quality: Avoid spilling liquids on the unit or discs.

Disc Handling:

Cleanliness: Handle discs by their edges. Store discs in cases or magazines when not in use.
Labels/Adhesives: Do not attach labels or use discs with sticky ink/residue, as this can cause malfunctions or damage.
Cleaning: Clean discs with a commercially available cleaning cloth, wiping from the center outwards. Do not use solvents like benzine, thinner, or antistatic sprays.
Disc Types: Do not use special-shaped discs (heart-shaped, octagonal) or 8cm (3in.) CDs.

Unit Maintenance:

Fuse replacement: Use a fuse matching the original amperage rating (10 A). If a fuse blows again after replacement, consult a Sony dealer.
Lithium battery replacement: The card remote commander uses a CR2025 lithium battery. Replace it when the remote's range shortens (approx. 1 year lifespan). Ensure correct polarity and avoid metallic tweezers. Keep batteries out of reach of children.
Cleaning connectors: If connectors between the unit and front panel become dirty, detach the front panel and clean them with a cotton swab dipped in alcohol. Avoid excessive force or touching with fingers/metal.

Troubleshooting:

No sound: Check volume, ATT function, fader control.
Memory erased: Reset button pressed, power cord/battery disconnected.
No beep sound: Optional power amplifier connected, or beep sound canceled.
Display issues: Clean connectors, check if OFF button was held for 2 seconds.
CD playback issues: Dirty/defective disc, unfinalized CD-R, incorrect disc insertion, high ambient temperature.
Radio reception issues: Weak broadcast signal, incorrect preset, local seek mode "ON," antenna connection problems, monaural reception mode.
Error displays: "E-04" (dirty/upside down CD), "E-99" (unit malfunction, press RESET).
