Detailed technical data for the unit's general, CD, FM, and AM tuner functions.
The VRCD400-SDU is a versatile in-car entertainment system that combines an AM/FM stereo receiver with a CD/MP3/WMA player, a USB port, and an auxiliary input, all housed within a detachable faceplate for added security. This unit is designed to provide a comprehensive audio experience for your vehicle, offering a wide range of playback options and user-friendly controls.
At its core, the VRCD400-SDU functions as an AM/FM MPX stereo receiver, allowing you to tune into your favorite radio stations across multiple bands. It boasts 30 preset memory slots, enabling you to quickly access your preferred FM and AM stations. The radio operation includes both automatic and manual seek functions, with two distinct seek modes (SEEK 1 for strong signals and SEEK 2 for continuous scanning) to help you find stations efficiently. You can also toggle between mono and stereo reception for improved signal quality in challenging areas. The unit supports both American and European frequency ranges, selectable via an A/E switch located behind the front panel.
Beyond radio, the device features a CD player capable of handling standard audio CDs, as well as MP3 and WMA files stored on CDs. When a disc is inserted, it automatically loads and begins playback, even if the unit is off or in radio mode. The CD player includes essential playback controls such as track selection (forward/backward), fast forward/reverse, pause/play, and scanning (playing the first 10 seconds of each track). For those with extensive music libraries, the unit offers repeat and random play functions for both CD and MP3/WMA tracks. A notable feature is the Electronic Skip Protection, offering 12 or 45 seconds of buffer to prevent interruptions on rough roads.
The VRCD400-SDU extends its media capabilities with a USB port and an SD memory card slot, allowing you to play MP3/WMA files directly from flash drives and SD cards. The unit automatically detects and begins playing files from these sources when inserted. Similar to CD playback, USB and SD card modes offer track selection, fast forward/reverse, pause/play, repeat, and random play. For MP3/WMA files, the unit supports ID3 tag display, showing track information on the digital LCD.
An auxiliary input (AUX IN) located on the front panel provides connectivity for external audio devices such as DVD or VCD players, or any portable audio source. This allows you to integrate a wide array of personal media players with your car's sound system.
The audio output capabilities are further enhanced by RCA line outputs for connecting external amplifiers, equalizers, or other audio components. Additionally, a dedicated subwoofer output is available for those who wish to add a subwoofer to their audio setup, complete with a subwoofer control function to fine-tune its output.
The VRCD400-SDU is designed for intuitive operation. The front panel features a liquid crystal display (LCD) that provides clear feedback on the current mode, track information, radio frequency, and time clock. A dual-channel level meter is also present for visual audio feedback.
Basic operations include a power on/off button, a volume/SEL knob that also functions as a sound select button, and a mode button to switch between AUX, RADIO, CD PLAY, USB, and MEM-CARD (SD card) modes. The SEL button is central to adjusting various audio settings such as bass, treble, balance, fader, and activating preset equalizer functions (POP, ROCK, FLAT, CLASSIC). Pressing and holding the SEL button allows access to advanced settings like subwoofer control and preset beep sound toggling.
The unit incorporates a loudness control to emphasize bass output, and a mute sound control for instant audio silencing. A time clock display is integrated, which can be set and viewed at any time.
For radio enthusiasts, the ASPS (Automatic Store/Preset Scan) memory control allows for automatic scanning and saving of strong radio stations across all bands. Manual preset buttons (1-6) enable you to save and recall your favorite stations.
MP3/WMA playback from CDs, USB drives, and SD cards benefits from various search modes, including simple track search, file search, and character search, making it easier to navigate large music libraries. The ID3 display provides song information directly on the LCD.
The detachable faceplate is a key security feature, allowing you to remove the front panel when leaving your vehicle, deterring theft. An infra-red remote control is included, offering convenient access to all major functions from a distance.
The manual emphasizes several maintenance and care guidelines to ensure the longevity and optimal performance of the VRCD400-SDU.
For disc care, users are advised to handle CDs by their edges to prevent smudges and scratches on the surface. It's crucial to avoid using CDs with labels or stickers, as these can peel off and leave sticky residue, potentially damaging the player. Similarly, discs with paste or ink residue should not be used. Cleaning discs should be done with an optional cleaning cloth, wiping from the center outwards.
Installation notes highlight the importance of proper wiring connections to prevent malfunction or damage to the vehicle's electrical system. Disconnecting the negative battery terminal before installation is recommended. The unit is designed for 12V DC negative ground systems and should only be used with four speakers, avoiding combining outputs for fewer speakers or grounding negative speaker leads to the chassis.
The manual also points out the need to remove two transport screws from the top of the unit before installation, which are used to secure internal components during shipping.
In case of operational issues, a simple troubleshooting guide is provided, covering common problems like no power, errors on the LCD, inability to receive stations, poor radio reception, CD loading issues, and skipping songs. Solutions typically involve checking wiring, pressing the reset button, ensuring proper antenna connection, or cleaning/formatting media.
The faceplate, being a precision electronic component, should not be subjected to excessive shock. The unit should also not be installed in locations exposed to direct sunlight, high heat, humidity, or dust to prevent damage. When replacing fuses, it's essential to use replacements with the same amperage as indicated on the fuse holder.
Regular cleaning of the unit's exterior, especially the faceplate and display, with a soft, dry cloth is recommended to maintain its appearance and functionality.
