This document describes the JENSEN CD-60C Personal Compact Disc Player, a portable audio device designed for playing commercial CDs, as well as self-compiled CD-R/CD-RW discs. The player emphasizes user safety and optimal listening experience through various features and recommendations.
Function Description
The JENSEN CD-60C is a personal compact disc player that allows users to listen to audio CDs on the go. It operates on two 1.5V DC "AA" size (UM-3) alkaline batteries or an optional 4.5V DC 700mA AC-DC adaptor. The device features a top-loading CD door for disc insertion and an LCD display that provides information about the current track, elapsed time, and various playback modes.
The core function of the player is to provide high-quality audio playback from compact discs. It includes an anti-skip protection system, which utilizes an electronic buffer to prevent sound interruptions during shock, vibration, or rolling movements. This system automatically activates when a disc is playing, indicated by a flashing ESP icon on the display. Once the buffer is full, it provides approximately 60 seconds of protection against sound interruption, ensuring a continuous listening experience even in motion.
For enhanced audio, the player incorporates a Bass Boost System (BBS) switch, which can be set to the ON position to increase bass performance. The effect of the bass boost may vary depending on the volume level.

The player also has an Auto Power Off function, which automatically switches off the power approximately 30 seconds after a disc finishes playing or when the CD lid is opened, helping to maximize battery life.

Maintenance Features
Proper care and maintenance are crucial for the longevity and optimal performance of the JENSEN CD-60C:
- Cleaning the Unit: The unit should be cleaned with a soft, damp (never wet) cloth. Solvents or detergents should not be used. It is important to prevent water or other liquids from entering the unit during cleaning.
- Disc Cleaning: If music drop-outs, interruptions, or playback failures occur, the bottom surface of the CD may need cleaning. Wipe the disc from the center outwards with a lint-free, soft cleaning cloth. Avoid attaching labels or seals to either side of CD-R/RW discs, as this can cause malfunctions.
- Battery Care:
- Always use the same or equivalent type of battery for replacement.
- Do not mix old and new batteries, or different types of batteries (alkaline, carbon-zinc, nickel-cadmium).
- Remove batteries if the unit will not be used for an extended period to prevent damage from leaks and to avoid voiding the warranty.
- Do not attempt to recharge batteries not intended for recharging, as they can overheat and rupture. Always follow the battery manufacturer's directions.
- Dispose of batteries properly; do not dispose of them in fire, as they may leak or explode.
- Environmental Considerations:
- Avoid operating the unit in direct sunlight, hot, humid, or dusty places to reduce the risk of fire or electric shock.
- Keep the unit away from heating appliances and sources of electrical noise like fluorescent lamps or motors.
- For better display clarity, avoid operating the unit under direct sunlight or in strongly illuminated rooms.
- General Safety:
- Never attempt to disassemble the casing, as the laser beam is harmful to the eyes.
- If any liquid or solid object falls into the cabinet, immediately stop operation, unplug the unit, and have it checked by qualified personnel.
- Do not touch or poke the lens, as this can damage it and impair player operation.
- Do not insert anything into the safety slot, as this will turn on the laser diode even when the lid is open.
- Unplug the unit from the electrical power outlet immediately in case of malfunction.
- Never wrap the earbuds cord around animals or people, and take special care with long wires.
- Avoid excessive volume levels for prolonged periods when using headphones, as this can impair hearing.
- Do not use earbuds while operating a motorized vehicle, as it can create a traffic hazard and is illegal in many areas.
The manufacturer emphasizes the importance of setting a safe volume level to protect hearing and recommends avoiding prolonged exposure to excessive noise to ensure a lifetime of musical enjoyment. The product also complies with FCC regulations and contains a Class 1 laser device, with warnings regarding invisible laser radiation when open.
