To avoid battery leakage If you dont use the remote for an extended period of time, remove the battery to avoid possible damage from battery leakage and corrosion. zWhen to replace the battery Under normal conditions, the battery should last for about six month
20、s. When the remote no longer operates the player, replace the battery with a new one. Notes on lithium battery Keep the lithium battery out of the reach of the children. Should the battery be swallowed, immediately consult a doctor. Wipe the battery with a dry cloth to assure a good contact. Be sure
21、 to observe the correct polarity when inserting the battery. Do not hold the battery with metallic tweezers, otherwise a short-circuit may occur. WARNING Battery may explode if mistreated.

About i.LINK This section explains the general specifications and major features of i.LINK. Read this section be
31、fore doing any i.LINK-related operation. Note that i.LINK connections and operations may vary, depending on the component. For details regarding the connection of i.LINK components to this player, see “Hooking Up the System” on page 4. i.LINK functions i.LINK is a serial digital interface that suppo
32、rts the bi- directional transmission of audio and video signals, commands, and even component status information. All that is needed to hook up i.LINK components are i.LINK connecting cables. Audio and video components connected within an i.LINK configuration can be used to perform a wide range of o
33、perations and data exchanges that is sure to expand as the number and variety of i.LINK components grow. Since i.LINK allows data to be transmitted from one component to other components to which it is not directly connected, there is no need to pay attention to connection order. However, due to dif
34、ferences in characteristics or specifications, operation of or data exchange with certain i.LINK components may not be possible, even when they are connected. zWhat is i.LINK? i.LINK is a trademark proposed by Sony Corporation and accepted by companies throughout the world as an easy-to-remember nam
35、e for the IEEE 1394 world standard of the Institute of Electrical and Electronics Engineers. 17GB Other Functions i.LINK connections The use of i.LINK cables to connect i.LINK components as shown below is called a “daisy chain” configuration. Data can be transmitted between any two components even i
36、f they are indirectly connected. Branch connections Any i.LINK component with three or more i.LINK connectors can serve as a branch point. Up to 63 i.LINK components can be connected in a single configuration. However, the maximum number of components that can be daisy-chained in a single route is 1
37、7 (i.e., a maximum of 16 i.LINK connecting cables in a row). Each i.LINK cable used in a single route is called a “hop.” For example, there are 6 hops in the route between A and C in the illustration below, and 3 hops in the route between A and D. BA DC Each route between A and B; A and C; A and D;
38、B and C; B and D; and C and D in the illustration above can have 16 hops (i.e., 17 components). Loop-connetion A signal output from one component is transmitted to all other components. A loop connection should thus be avoided to prevent the return of a signal to its source. Notes Some i.LINK compon
39、ents (such as personal computers) do not transfer signals when they are turned off. Refer to the operation manual of each component to be connected before you hook them up. The maximum transmission rate of an i.LINK component is printed near its i.LINK connector. The indications S100, S200, and S400
40、 refer to maximum transmission rates of 100, 200, or 400 Mbps*, respectively. The actual transmission rate may be faster or slower, depending on the differences in transmission rates and specifications among the connected components. zWhat is Mbps? “Mbps” is an abbreviation for megabits per second.
41、It indicates the amount of data transmitted per second. For example, a rate of 200 Mbps means 200 megabits of data are transmitted in one second.

42、ansmitted between i.LINK components, a “LINC” must first be established between the receiving component (of the audio signal) and the sending component. Establishing a “LINC” means establishing a logical path for the transmission of digital audio signals between the two components. Each logical path
43、 has an ID number. Since the component that sends an audio signal must output the signal to a path, and the component that receives the signal must input it from the same path, the path must be mutually known by both components. During the establishment of a LINC, the following communication occurs
44、between the two i.LINK components. Example A component establishing a LINC with a CD player in order to receive an audio signal from the CD player 1The component that will receive an audio signal from the CD player sends a request and path information to the CD player to establish a transmission path for the audio signal. 1 , 2 button “CD KEY 5” : . button “CD KEY 6” : DISPLAY button “CD KEY 7” : ?/1 button 2.
