Jensen VR180 manual Handling Compact Discs, Some Facts about AM and FM Reception

HANDLING COMPACT DISCS

--Do not attempt to use 3"(8cm) CD-Single discs in this unit, either wit- h or without an adaptor, as damage to the player and/or disc may o- ccur. Such damage will not be covered by the Warranty on this produ- ct.

--When not using the disc player, always remove the compact disc. Do not leave an ejected disc sitting in the disc slot as this can expos- e it to sunlight and other causes of damage.

--Do not attempt to open the unit chassis. There are no user serviceab- le parts or adjustments inside .

--When the vehicle warms up during cold weather or under damp cond- itions, moisture may condense on the lens of the disc player, should this occur, the player will not operate properly until the moisture has evaporated.

--The unit is designed with a vibration dampening CD mechanism to m- inimize interruption of disc play due to normal vibration in a moving vehicle. When driving on very rough roads, however, occasional sou- nd skips may occur. This will not scratch or damage the disc and nor- mal play will resume when the rough conditions cease.

HANDLING COMPACT DISCS

Dirt, dust, scratches, and warped discs can cause skips in the playback and deterioration of sound quality. Please follow these guidelines to tak- e care of your compact discs:

--Use only compact discs with the mark

--Fingerprints, dust, and dirt should be carefully wiped off the disc's pl- aying surface(shiny side) with a soft cloth. Wipe in a straight motion from the inside to the outside of the disc.

--Never use chemicals such as record sprays, household cleaners or thinner to clean compact discs. Such chemicals can irreparably dam- age the disc's surface.

--Discs should be kept in their storage cases when not in use.

--Do not expose discs to direct sunlight, high temperatures or high hum- idity for extended periods.

-- Do not stick paper, tape, or labels on the disc surfaces.

AM AND FM RECEPTION IN A MOBILE ENVIRONMENT

Although you may be familiar with both AM and FM reception in your

SOME FACTS ABOUT AM AND FM RECEPTION

home, you will experience notable differences in reception while driv- ing your vehicle.

Both AM and FM provide excellent listening enjoyment and supply th- e diversified entertainment while in your vehicle. FM reception provid- es a different listening experience compared to that of AM. The few reception inconveniences common to FM are compensated by the ri- ch sound quality of its wide frequency response and stereo effect. Your new AM/FM radio has been built to the strictest engineering sta- ndards available today and through quality under all conditions. A few minutes reading this section will enable you to obtain the most from the unit and answer your questions about the differences between m- obile AM and FM reception.

SOME FACTS ABOUT AM AND FM RECEPTION

1.RECEPTION IN TUNNELS: Although you will lose AM reception w- hen driving through tunnels and large bridges, it is common to con- tinue to receive FM reception under the same conditions.

2.THE NUMBER OF STATIONS IN YOOUR AREA: Depending on your location, you may find that you can receive a greater number of AM stations in your area than FM stations. In most urban and suburban areas, the numbers of AM and FM stations are compara- ble.

3.RECEPTION DURING STORMS: Local electrical thunderstorm a- ctivity often produces sharp static sound when listening to AM sta- tions although you will find that FM is unaffected.

4.ELECTRICAL INTERFFRENCE: When listening to AM stations, you may experience some buzzing sounds or static when passing roadside electric power lines which do not interfere with FM recep- tion. Conversely, FM reception may be affected by electrical noise from passing cars and trucks while AM reception is not affected.

5.FM RECEPTION RANGE: FM reception range is usually limited to about 50 miles from the broadcast station. FM signals radiate stra- ight out from the broadcast antenna. They do not follow the earth's curve and are not reflected back to the earth by the atmosphere r- esulting in"line-of-sight"reception range.

6.AM RECEPTION RANGE: AM stations can often be received hun- dreds of miles from the broadcast station. AM signals follow the ea- rth's curve and are easily reflected back to earth by the atmosphere.
