7、xposure or other unsafe operation. POWER SUPPLY Whenever convenient, use the AC power supply to conserve battery life. Make sure you remove the power plug from the set and wall socket before inserting batteries. Batteries (not included) Insert 6 batteries, type R-14, UM-2 or C-cells, (preferably alk

8、aline) with the correct polarity. (See 6) Remote control Insert 2 batteries, type AAA, R03 or UM4 (preferably alkaline). (See 8) IMPORTANT ! Incorrect use of batteries can cause electrolyte leakage and will corrode the compartment or cause the batteries to burst. Do not mix battery types: e.g. alkal

9、ine with carbon zinc. Only use batteries of the same type for the set. When inserting new batteries, do not try to mix old batteries with the new ones. Batteries contain chemical substances, so they should be disposed of properly. Using AC Power 1.Check if the AC power supply, as shown on the type p

31、E INFORMATION (See 7) Dont expose the set, batteries, CDs to humidity, rain, sand or excessive heat. Clean the set with a dry cloth. Dont use any cleaning agents containing alcohol, ammonia, benzene or abrasives as these may harm the set. Place the set on a hard and flat surface so that the system d

32、oes not tilt. Make sure there is good ventilation to prevent the set overheating. The mechanical parts of the set contain self-lubricating bearings and must not be oiled or lubricated. CD player and CD handling If the CD player cannot read CDs correctly, use a cleaning CD to clean the lens before ta

33、king the set to repair. The lens of the CD player should never be touched! Sudden changes in the surrounding temperature can cause condensation on the lens of your CD player. Playing a CD is then not possible. Do not attempt to clean the lens but leave the set in a warm environment until the moistur

34、e evaporates. Always close the CD door to avoid dust on the lens. To clean the CD, wipe in a straight line from the centre towards the edge using a soft, lint-free cloth. Do not use cleaning agents as they may damage the disc. Never write on a CD or attach any stickers to it. RAMNo sound /power Volu
