Careless handling duringrepair can reduce life drastically.When repairing, make sure that you are connected with thesame potential as the mass of the set via a wristband withresistance. Keep components and tools at this potential.f ATTENTIONTous les IC et beaucoup dautres semi-conducteurs sontsensibles aux dcharges statiques (ESD).

To clean the set, use a soft, slightly dampened chamoisleather. Do not use any cleaning agents containing alcohol,ammonia, benzene or abrasives as these may harm thehousing.Safety information Place the set on a hard and flat surface so that the systemdoes not tilt. Make sure there is adequate ventilation toprevent the system from overheating. The mechanical parts of the set contain self-lubricatingbearings and must not be oiled or lubricated.SEARCHSTOP-OPENPAUS EDBBPOWERTUNERDYNAMIC BASS BOOSTCDTAPEOFFCD SHUFFLESTOP-OPENPAUS EDBBPOWERTUNERDYNAMIC BASS BOOSTCDT APEOFFVOLUMECDREMOTESENSORSHUFFLEALLPROG.PRESETBATTLOWMODET APETUNERCDSTOPPLAYPAUSESEARCH SEARCHREMOTESENSOR Whenever convenient, use the AC mains supply if you want toconserve battery life. Make sure you remove the plug from theset and wall socket before inserting batteries.BATTERIES (OPTIONAL) 1. Open the battery compartment and insert six batteries, type R-20, UM-1 or D-cells, (preferably alkaline) with the correctpolarity as indicated by the + and - symbols inside thecompartment.Remote control (supplied)Open the battery compartment and insert two batteries, type AAA, R03 or UM4 (preferably alkaline).2. Replace the compartment door, making sure the batteries arefirmly and correctly in place. The set is now ready to operate. If BATT LOW lights up, battery power is running low. The BATT LOW indicator eventually goes out if thebatteries are too weak.Incorrect use of batteries can cause electrolyte leakage and willcorrode the compartment or cause the batteries to burst.Therefore: Do not mix battery types: e.g. alkaline with carbon zinc. Only use batteries of the same type for the set. When inserting new batteries, do not try to mix old batterieswith the new ones. Remove the batteries if the set is not to be used for a longtime.Batteries contain chemical substances, so they shouldbe disposed of properly.For users in the U.K.: please follow the instructions on page 2.Using Mains1. Check if the mains voltage as shown on the type plate onthe bottom of the set, corresponds to your local mainssupply. If it does not, consult your dealer or service centre.2. If your set is equipped with a voltage selector, adjust theselector so to match with the local mains supply.3. Connect the mains lead to the wall socket and the set is nowready for use.4. To disconnect the set from the power supply completely,remove the plug from the wall outlet.Standby power consumption . . . . . . . . . . . . . . . . . . . . . . . .3 W6 x R20 UM-1 D-CELLS PCS 107 1153-3INSTRUCTIONS FOR USE1.
