SONY WALKMAN CD PLAYER D-NF340 REVIEW (Part 2) Technical support for the Sony Walkman CD Player D-NF340 including operating instructions and complete marketing specifications documents is provided by the manufacturer on its SonyStyle website. The installed compact disc must be removed from the Sony CD Walkman D-NF340 prior to replacing the AA batteries. Customers must observe correct battery polarity alignment in the battery compartment at all times. Consumed AA batteries should be removed before installation of fresh name brand alkaline batteries. The removal of consumed AA batteries from the interior battery compartment is a simple process as long as the operating manual battery removal instructions are followed by the customer. The Sony Walkman CD Player D-NF340 features programmable track memory. Programmable track memory allows the user to store a limited number of songs or the maximum number of tracks on any particular Red Book CD-DA compliant audio disc or MP3 CD into the Sony Walkman’s nonvolatile memory storage system. The Sony Walkman CD Player D-NF340 can store up to 99 bookmarks per audio CD or up to 512 compressed files per MP3 CD. For example, the customer may program or set into bookmark memory the following tracks on an audio disc that features 20 tracks: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, and 12. You must press and hold the Play/Pause/Enter button during playback of a track to add a bookmark to it and repeat the same procedure to add as many bookmarks as you wish. A flashing bookmark indicator appears in the LCD when a bookmark has been added to a particular track. You can prioritize the tracks that you want in bookmark memory and leave undesired tracks out in this scenario. Bookmark play mode always begins playback from the lowest track number that contains a bookmark. However, you can always skip back and forth between bookmarks as many times as needed. In addition, the Sony Walkman CD Player D-NF340 combines the shuffle play feature and program CD play modes into one function. The bookmark shuffle program mode allows the customer to store tracks into memory and then play the pre-programmed bookmark selection back in random order play mode. In this instance, the random play mode add-on keeps your music fresh, dynamic, always changing, and allows the customer to remove undesirable tracks at their next private listening session. The bookmark program play mode selection can be repeated. Bookmark program play mode is cancelled once the playback audio CD/MP3 CD is changed or the user presses and holds the Play/Pause/Enter button during playback of a bookmarked track to remove the bookmark(s). Sony refers to the programmable track memory feature on this Sony Walkman CD Player D-NF340 simply as Bookmark Playback Function. The bookmark program track memory play mode will work with homemade CD-R/RW discs, MP3 CDs, store purchased audio discs, 12 cm audio discs, 8 cm audio discs, audio books on CD, and compressed file MP3 audio discs made with the Microsoft Windows Media Player as long as the Sony Walkman CD Player D-NF340 supports those types of media playback. Bookmarked programmed tracks or MP3 files can be cancelled, partially deleted, deleted, or edited in its entirety before playback commences on the Sony Walkman CD Player D-NF340. The bookmark program play mode can be engaged by the end-user at any time. Bookmark program play mode is not supported on non-standard shaped audio discs. This Sony Walkman CD Player D-NF340 is a superb battery powered news information resource tool to have during an inclement weather situation, natural disaster such as a coastal flood, avalanche, lightning strike, or short-term power outage incident. The Sony Walkman CD Player D-NF340 can be made part of an emergency prep kit in advance of a natural disaster, severe weather event, unplanned weather events, high wind warning, tornado, water main break, building collapse, bridge collapse, construction site accident, boating vessel accident, gasoline shortage, plane crash, train derailment, drought conditions, emergency water usage restrictions, water supply contamination, manmade catastrophe, terrorist attack, explosion, asteroid collision, during periods of civil unrest, or to receive notice of abhorrent criminal conduct taking place in the neighborhood on FM Band news radio broadcasts. I can’t recommend a wind-up hand crank radio. I have never reached a point in my life that I have witnessed a complete AA alkaline disposable battery shortage. I have never run out of AA battery power during a power outage that I can remember. AA alkaline batteries are one of the most ubiquitous items for sale in the U.S. Single-use AA alkaline batteries can be purchased at almost any type of store anywhere. Yes there are some exceptions, but not many in my experience. However, AA alkaline batteries tend to become scarce immediately before, during, or after a severe storm and power outage. One way to avoid a temporary AA alkaline battery shortage and loss of battery power is to buy a spare set or several spare sets of AA batteries for the Sony Walkman CD Player D-NF340 in case you can’t find a store that sells AA alkaline batteries at the current moment. The spare set of AA batteries will last you much longer than the self-powered wind-up rechargeable radio. I recommend Duracell Ultra Power DURALOCK Power Preserve Technology 1.5V AA alkaline batteries or Energizer Ultimate Lithium 1.5V AA batteries for maximum sustained battery life performance of the Sony Walkman CD Player D-NF340 during emergency events as circumstances require. A spare set of Duracell Ultra Power DURALOCK Power Preserve Technology and Energizer Max Power Seal Technology AA alkaline batteries can maintain full power in the product packing for up to 10 years from the current date of purchase. Energizer Ultimate Lithium AA batteries can maintain full power in the product packaging for up to 15 years from the current date of purchase. As a result, long-term storage of AA alkaline or lithium batteries is a favorable option to power the Sony Walkman CD Player D-NF340 during almost any nightmare public endangerment scenario. However, a wind-up radio may be a more desirable portable AM/FM/Shortwave/WB radio to take on a long camping trip, hunting trip, fishing excursion, or to have during a very long-term power outage situation. The Sony Walkman CD Player D-NF340 offers magnificent battery life on one set of AA alkaline or lithium batteries and that is sufficient reason alone for me not to recommend a wind-up radio. Wind-up radios may also be inconvenient for customers that suffer from arthritis, joint diseases, or other maladies that cause pain in the hands. Lastly, the Sony Walkman CD Player D-NF340 offers better sound quality from its robust stereo headphone speakers on FM radio broadcasts and superior alkaline battery life, when compared to a wind-up radio, in order to provide increased voice clarity on vital up-to-the-minute weather reports, traffic updates, voluntary evacuation orders, and mandatory evacuation orders on the FM Band at any time to the end-user. The perceived loudness of the Sony Walkman CD Player D-NF340 will ultimately depend on numerous objective and subjective factors. The quality of the Sony Walkman CD Player D-NF340’s internal headphone amplifier will play a crucial role in determining how loud the volume levels the Mega Bass Portable CD Player can be played back at through attached stereo headphones during lengthy private music sharing sessions. Typically, most portable audio devices such as an MP3 Player or portable compact disc player feature low-powered built-in headphone amplifiers ranging between 5-15 mW at a designated impedance level. Conversely, the headphone amplifiers found in component stereo equipment may be rated up to 500mW at a designated impedance level. A component stereo receiver can power stereo headphones with a much higher impedance rating of 70-300 ohms or greater more efficiently when compared to a Sony Walkman CD Player D-NF340’s 16-68 ohms built-in stereo headphone amp. A component stereo receiver or integrated amplifier makes use of a Full-Size .25-inch (6.3mm) Stereo Headphone Output Jack to deliver increased amplifier output power to consumer grade dynamic driver home theater stereo headphones. Nonetheless, a portable audio device, such as the Sony Walkman CD Player D-NF340, uses a smaller 3.5mm (1/8”) Stereo Headphone Jack that can’t deliver the same amount of loudness as the ¼” Full-Size Headphone Jack found on its component stereo counterpart. A headphone driver’s sensitivity rating plays an important factor in loudness perception on the Sony Walkman CD Player D-NF340. As a result, it is important for most consumers to consider purchasing dynamic stereo headphones that are rated between 98-117db/mw on its driver sensitivity specification to achieve satisfying loudness levels on the Sony Walkman CD Player D-NF340. The Sony Walkman CD Player D-NF340 is capable of producing substantial Mega Bass loudness results in less than favorable operating conditions on a daily basis. Consumers that are looking for extra loudness to block out external unwanted environmental noise during private listening sessions on the Sony Walkman CD Player D-NF340 will seek to purchase stereo headphones with a better than average sensitivity rating. The higher the sensitivity rating, the louder the headphones will play without the need to turn the digital Volume control all the way up on the Sony Walkman CD Player D-NF340. Loudness perception of the Sony Walkman CD Player D-NF340 is subject to the limits of human hearing. Some customers can hear sound waves better than other customers. The hearing levels of all Sony customers are just not the same. Therefore, some customers may report that the Sony Walkman CD Player D-NF340 doesn’t play loudly enough from its connected stereo headphones, while other customers will frustratingly opine that the portable CD player plays too loudly for their tastes when adjusting the digital Volume controls. The Sony Walkman CD Player D-NF340 is capable of reproducing the entire frequency spectrum of human hearing. A dedicated third party headphone amplifier can be purchased to augment headphone loudness output from the Sony Walkman CD Player D-NF340’s 3.5mm Stereo Headphone Jack. Ultimately, your choice of stereo headphones will greatly affect the sound quality and overall loudness output that you encounter during prolonged private listening sessions on the Sony Walkman CD Player D-NF340. Principles of FM Band radio wave propagation, theories of psychoacoustics, the laws of physics, Windows Media Player file compression MP3 CD bit rates, and the recording quality of the music being listened to will determine whether or not there are extremely loud playback levels from the Sony Walkman CD Player D-NF340’s attached stereo headphones. Customers can consider purchasing the Sony Walkman CD Player D-NF340 to augment their perception of loud volume levels across the wide variety of musical or spoken word entertainment categories on compact disc media and FM radio.
