After the STANDBY indicator � stops �ashing, reconnect the power cord, and turn on the system. If the issue persists, contact your nearest Sony dealer.

On safety

� The unit is not disconnected from the AC power source (mains) as long as it is connected to the wall socket, even if the unit itself has been turned off. � Completely disconnect the power cord (mains lead) from the wall socket (mains) if it is not going to be used for an extended period of time. When unplugging the unit, always grip the plug.

Tips
� The Play Timer setting remains as long as the setting is not canceled manually. � The volume is reduced to minimum during the Rec Timer. � The Rec Timer is canceled automatically after the Rec Timer has been activated.

� Do not place the system in an inclined position or in locations that are extremely hot, cold, dusty, dirty, or humid or lacking adequate ventilation, or subject to vibration, direct sunlight or a bright light. � Be careful when placing the unit or speakers on surfaces that have been specially treated (for example, with wax, oil, polish) as staining or discoloration of the surface may result. � If the system is brought directly from a cold to a warm location or is placed in a very damp room, moisture may condense on the lens inside the CD player, and cause the system to malfunction. In this situation, remove the disc, and leave the system turned on for about a few hours until the moisture evaporates.
