• 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.

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.

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.

For updating firmware for the CD I/F and CD DSP microcomputers, create separate discs for updating each microcomputer then play the disc on the unit.

1. Write a ***.UPG file onto a CD-R/RW to create the disc for updating. Examples of file names (File names vary, depending on the version of firmware.) For the CD I/F microcomputer: HM71_81CD_IFM_V1_00_110713.UPG For the CD DSP microcomputer: HM71_81CD_DSP_V102_(20110720_VT).UPG

File writing can be performed, using the writing function of Windows XP. Note: Create separate discs for updating the CD I/F and CD DSP microcomputers. If two files for updating these microcomputers are written on one disc, a problem may occur. NEVER write files other than a .UPG file onto the CD-R/RW for updating.

2. Turn the unit ON.

3. Set the Function selection to CD.

4. Open the disc tray, load the created disc, then close the tray.

5. Updating starts automatically.

6. After updating is completed, the disc tray will be automatically opened.

7. Unload the disc then turn the unit OFF.
