• For environmental protection, lead-free solder is used on the printed circuit boards mounted in this unit. Be sure to use lead-free solder and a soldering iron that can meet specifications for use with lead-free solders for repairs accompanied by reworking of soldering.

• Compared with conventional eutectic solders, lead-free solders have higher melting points, by approximately 40 ºC. Therefore, for lead-free soldering, the tip temperature of a soldering iron must be set to around 373 ºC in general, although the temperature depends on the heat capacity of the PC board on which reworking is required and the weight of the tip of the soldering iron.

Do NOT use a soldering iron whose tip temperature cannot be controlled. Compared with eutectic solders, lead-free solders have higher bond strengths but slower wetting times and higher melting

temperatures (hard to melt/easy to harden). The following lead-free solders are available as service parts:

• Parts numbers of lead-free solder: GYP1006 1.0 in dia. GYP1007 0.6 in dia. GYP1008 0.3 in dia.

It is necessary to remove the soldering on the short circuit point after connecting the pickup flexible cable.

Short circuit point

After the CR870 module is replaced alone or the whole BCO Assy, including the CR870, is replaced, the MAC address will be changed. Replace the MAC address seal with a new one, which you can find enclosed with the service part.

Attach the Mac Address label to the rear panel, above the WLAN antenna, so that it will not block the ventilation holes on the rear panel.

When ordering service parts, be sure to refer to "EXPLODED VIEWS and PARTS LIST" or "PCB PARTS LIST".

The > mark found on some component parts indicates the importance of the safety factor of the part.

Therefore, when replacing, be sure to use parts of identical designation.

: The power supply is shown with the marked box.

If a protection circuit is activated then the unit enters Standby mode, the LED flashes in accordance with the activated protection function, as shown in the table below.

The DC outputs from AMP_OUT_L and AMP_OUT_R are detected to avoid DC current surge to the speakers and excess voltage at B+ (+33 V). The protection circuit is activated when the signal at Pin 3 of IC601 changes from H to L.

If the DC, POWER, or PWM protection circuit is activated, operation of the unit will be locked. The buttons that can be used to release operation lock are as follows: Simultaneously press the "INPUT" and "np" (Tune Up, Skip Up) buttons on the front panel, or simultaneously press the "STANDBY/ON" and "g" (STOP) buttons on the front panel. After operation lock is released and the unit is then turned ON, the unit will perform the following:

• Count the number of activations of protection circuits

• Cancel flashing of the LED

The power supply state transition of this unit becomes the right figure. Cold Standby:

Mode in which power consumption becomes lowest Only the main microcomputer among all the microcomputers is powered.

Power On: Mode in which AC Relay is turned ON and all microcomputers are powered

iPod Charge: Mode in which an iPod is inserted in its dock in modes other than Power On In this mode, an iPod device that is plugged into the USB terminal or the dock can be charged. The power-supply status is the same as that during power-on with an HP inserted.

Network Standby: Mode in which the LCD is unlit with Bco powered in order to save startup time of Bco The audio and video output signals are muted, and the keys and buttons other than the STANDBY/ON key are masked. Basically, this mode is the same as iPod Charge mode.

Note: The power-off status caused by activation of a protection circuit is not described in this section. See "5.2 Protection circuit."

Connect the PC and this unit directly then set them up as indicated below. Then, access this unit from the PC via a Web browser. If the indications shown in the figure below are displayed, the LAN terminal is normal. If the LAN terminal is not normal, check the circuit between the LAN terminal and CR870 (Module on BCO Assy).

1 Turn the unit on. 2 Select the NETWORK function then press SETUP. 3 Select Network Setup > Connection Setup > Wired >

DHCP OFF. 4 Set the following items as shown below: IP address: 192.168.0.1 Subnet mask:255.255.255.0 Gateway address: 0.0.0.0 DNS (1st): 0.0.0.0 DNS (2nd): 0.0.0.0 Proxy setting: Not to be used 5 After setting is finished, reboot the unit.

Make preparations on the wireless LAN router side then check that the SSID for that router is displayed, following the procedure shown below. If the SSID is displayed on the LCD, the Wi-Fi antenna works properly. If the SSID is not displayed, check the wireless LAN antenna, CR870 (Bco Module), and the cable that connects them. (In the following LCD-display examples, the language setting is English.)

2. Checking the Wi-Fi Antenna

Start the Web browser, input http://192.168.0.1 as a URL. If the screen as indicated below is displayed, the LAN terminal works properly.

If this screen is displayed, the LAN terminal works properly.

If the SSID for the prepared router is displayed on the list, the Wi-Fi antenna works properly.

Note:

As the SSID name for a wireless LAN router supports only one-byte alphanumerics, if two-byte characters are used in an SSID name, rename it.

1. Select the NETWORK function then press SETUP.

2. Select Network Setting → Network Configuration.

3. Select Wireless.

4. Select Auto.

5. SSID list is displayed.

3. Checking the BT Adapter Terminal

If you connect the AS-BT100 or AS-BT200 as shown in the following steps, you can recognize if this unit works properly:

1. Select the BT function, connect the AS-BT100 or AS-BT200, then check that the indication changes as shown in the figure below.

4. Checking the USB Terminal

This unit is provided with a USB-path switch (IC12) that switches the paths to the CR870, module on BCO Assy, between the front USB terminal and the upper Docking Terminal, according to the selected function. Accordingly, the behavior of the USB terminal differs, depending on which path is selected. Therefore, checking is required both with the USB and iPod functions.

1. Select the USB function then connect an Apple Device (iPod, etc.) to the USB terminal. If the Apple device is recognized, it is OK. If "No Data" on the LCD disappears, the device is recognized. If possible, with the device connected, play a track to check the audio signal for confirmation.

2. Select the iPod function then connect an Apple Device (iPod, etc.) to the USB terminal. If charging of the Apple device starts, it is OK.

If charging does not start, refer to the diagnosis flowchart for a case in which the USB terminal cannot be recognized on "5.1 TROUBLESHOOTING".

5. Checking the Docking Terminal

The check procedure is similar to that for "4. Checking the USB Terminal," except for one additional verification. The Docking Terminal is provided with a function that detects a connection of an Apple device during power-off and starts charging. This additional function must be also verified.

1. Select the iPod function then put an Apple device (iPod, etc.) in the Dock. If the Apple device is recognized, it is OK. If "No Data" on the LCD disappears, the device is recognized. If possible, with the device connected, play a track to check the audio signal for confirmation.

2. Select the USB function then put an Apple device (iPod, etc.) in the Dock. If charging of the Apple device starts, it is OK.

3. Disconnect the Apple device from the dock then turn the unit off. Reconnect the Apple device to the Dock. If the CHARGE LED lights and charging starts, it is OK.

If charging does not start, refer to the diagnosis flowchart for a case in which the Docking Terminal cannot be recognized on "5.1 TROUBLESHOOTING"..

If the indication does not change as shown in the above figure, possible causes are as follows: "No Adapter" remains displayed:

The CR870, module on BCO Assy, cannot detect connection of the AS-BT100/200. Check BT_DET. The indication stops at "Starting":

The CR870, module on BCO Assy, cannot communicate with the AS-BT100/200. Check power supply to the AS-BT100/200 and the UART communication line. Signal lines to be checked: BT_ON/CE, BT_+5V, BT_TX/U_RX, BT_RX/U_TX

2. If the indication changes properly in Step 1, perform pairing with a player then check the audio output signals. If no audio signal is output, check BT_L, BT_R, and BT_MUTE.

After the AS-BT100/200 is connected, the indication will change as follows: No Adapter -> Starting -> Waiting Device.
