CONNECTIONS AND CONTROLS 2-2 POWER SUPPLY / GENERAL INFORMATION Use only the AY 3170 adapter (4.5 V / 300 mA direct current, positive pole to the center pin). Any other product may damage the player. 1 Make sure the local voltage corresponds to

31、the power adapters voltage. 2 Connect the power adapter to the 4.5V DC socket of the player and to the wall socket. Note: Always disconnect the adapter when you are not using it. Environmental information All redundant packing material has been omitted. We have done our utmost to make the packaging

Do not expose the unit, batteries or CDs to humidity, rain, sand or excessive heat (caused by heating equipment or direct sunlight). You can clea

34、n the CD player with a soft, slightly dampened, lint-free cloth. Do not use any cleaning agents as they may have a corrosive effect. To clean the CD, wipe it in a straight line from the center toward the edge using a soft, lint-free cloth. A cleaning agent may damage the disc! Never write on a CD or

35、 attach a sticker to it. The lens may cloud over when the unit is moved sud- denly from cold to warm surroundings. Playing a CD is not possible then. Leave the CD player in a warm environment until the mois- ture has evaporated. Active mobile phones in the vicinity of the CD player may cause malfunc

36、tions. Avoid dropping the unit as this may cause damage. Headphones HE 035 Connect the supplied headphones to the LINE OUT/p jack of the player. Note:LINE OUT/pcan also be used for connecting this set to your HiFi system.To adjust the sound and volume, use the controls on the connected audio equipme

37、nt and on the CD player. IMPORTANT! Hearing safety: Do not play your headphones at a high vol- ume. Hearing experts advise that continuous use at high volume can permanently dam- age your hearing. Traffic safety: Do not use headphones while driving a vehicle. It may create a hazard and it is illegal

38、 in many countries. Even if your headphones are an open-air type designed to let you hear outside sounds, do not turn up the volume so high that you cannot hear what is going on around you.
