This document describes the SYLVANIA Portable CD Boombox with AM/FM Radio, model SRCD1025, an instruction manual for a versatile audio device designed for portable use. The boombox offers multiple audio playback options, including CD, CD-R/RW, AM/FM radio, and an auxiliary input for external devices. It can be powered by either AC current or batteries, making it suitable for both home and on-the-go listening.
Function Description:
The SYLVANIA SRCD1025 is primarily a portable audio player. Its core functions include:
- CD Playback: It features a CD player capable of playing standard audio CDs as well as CD-R/RW discs. Users can play, pause, stop, skip between tracks, and search within a track. A unique feature is the ability to program up to 20 CD tracks, allowing for customized playback sequences. The repeat function allows users to repeat the current track or the entire album.
- AM/FM Radio: The boombox includes an integrated AM/FM radio tuner. Users can select either AM or FM mode using the Power Switch and then tune to desired stations using the Tuning Dial. The built-in antenna for both AM and FM ensures reception without external attachments.
- Auxiliary Input: For expanded connectivity, the device provides an Auxiliary Input (AUX IN) jack. This allows users to connect external audio sources, such as MP3 players, smartphones, or other devices, using a mini-phono 3.5mm cable (not included). Audio from the connected external device is then played through the boombox's built-in speakers.
Usage Features:
The boombox is designed for ease of use with clearly labeled controls and straightforward operation:
- Control Layout: Key controls are located on the top and front of the unit for easy access. These include the Stop Button, Program Button, Skip/Search Buttons, Play/Pause Button, Repeat Button, Volume Dial, Power Switch, and Tuning Dial.
- Power Options: The device offers dual power capabilities. It can be powered by plugging the detachable AC cord into a standard AC outlet (120V~60Hz). Alternatively, for portable use, it requires six C-size batteries (not included), which are inserted into a battery compartment.
- Volume Control: A dedicated Volume Dial allows for precise adjustment of the audio output level from the built-in speakers.
- LED Display: A 2-digit red LED display provides visual feedback, likely for track numbers in CD mode or other operational indicators.
- Built-in Speakers: The unit comes with integrated speakers, eliminating the need for external audio output devices.
Maintenance Features:
The manual emphasizes safety and proper care to ensure the longevity and safe operation of the device:
- Cleaning: Users are instructed to unplug the product from the wall outlet before cleaning and to use only a dry cloth. Liquid or aerosol cleaners are explicitly prohibited.
- Ventilation: The cabinet features slots and openings for ventilation, which must not be blocked or covered to prevent overheating. The product should not be placed on soft surfaces like beds or sofas, or in enclosed spaces like bookcases, unless proper ventilation is ensured.
- Power Cord Protection: The power supply cord should be routed to prevent it from being walked on or pinched, with particular attention to the plug, convenience receptacles, and the point where it exits the product.
- Safety Warnings: The manual includes several warnings regarding electrical shock, laser radiation (for the CD player), and proper battery usage. It advises against mixing old and new batteries or different types of batteries.
- Servicing: Users are explicitly warned not to attempt to service the product themselves, as opening the cover may expose them to dangerous voltage. All servicing should be referred to qualified service personnel.
- Environmental Considerations: The device should be kept away from water and moisture, and no objects filled with liquids should be placed on it. It should also be situated away from heat sources like radiators, heat registers, stoves, or other heat-producing appliances.
- Antenna Grounding (for external antenna, if applicable): While the unit has a built-in antenna, for any potential external antenna connection, the manual provides detailed instructions on proper grounding according to the National Electrical Code to protect against voltage surges and static charges.
- Lightning Protection: During lightning storms or when left unused for extended periods, users are advised to unplug the unit from the wall outlet and disconnect any antenna or cable system to prevent damage from lightning and power-line surges.
- FCC Compliance: The device complies with Part 15 of the FCC Rules, indicating it has been tested and found to meet limits for a Class B digital device, designed to provide reasonable protection against harmful interference in a residential installation.
- Hearing Protection: A warning is included regarding excessive sound pressure from earphones and headphones, which can cause hearing loss, although the boombox itself does not appear to have a headphone jack based on the provided diagrams.
