SERVICING PRECAUTIONS
Always disconnect the power source before:
1) Removing or reinstalling any component, circuit board, module or any other instrument assembly.
2) Disconnecting or reconnecting any instrument electrical plug or other electrical connection.
3) Connecting a test substitute in parallel with an electrolytic capacitor in the instrument.
CAUTION: A wrong part substitution or incorrect polarity installation of electrolytic capacitors may result in
an explosion hazard.
Do not defeat any plug/socket B+ voltage interlocks with which instruments covered by
this service manual might be equipped.
Do not apply power to this instrument and or any of its electrical assemblies unless all
solid-state device heat sinks are correctly installed.
Always connect a test instrument’s ground lead to the instrument chassis ground before
connecting the test instrument positive lead. Always remove the test instrument ground lead last.
1) The service precautions are indicated or printed on the cabinet, chassis or components. When servicing, follow the printed or indicated service precautions and service materials.
2) The Components used in the unit have a specified conflammability and dielectric strength. When replac­ing any components, use components which have the same ratings. Components marked in the cir­cuit diagram are important for safety or for the characteristics of the unit. Always replace with the exact components.
3) An insulation tube or tape is sometimes used and some components are raised above the printed writing board for safety. The internal wiring is sometimes clamped to prevent contact with heating components. Install them as they were.
4) After servicing always check that the removed screws, components and wiring have been installed cor­rectly and that the portion around the service part has not been damaged. Further check the insulation between the blades of attachment plug and accessible conductive parts.

ESD PRECAUTIONS
Electrostatically Sensitive Devices (ESD)
Some semiconductor (solid state) devices can be damaged easily by static electricity. Such components commonly are called Electrostatically Sensitive Devices (ESD). Examples of typical ESD devices are integrated circuits and some field-effect transistors and semiconductor chip components.The following techniques should be used to help reduce the incidence of component damage caused by static electricity.
1. Immediately before handling any semiconductor component or semiconductor-equipped assembly, drain off any electrostatic charge on your body by touching a known earth ground. Alternatively, obtain and wear a commercially available discharging wrist strap device, which should be removed for potential shock reasons prior to applying power to the unit under test.
2. After removing an electrical assembly equipped with ESD devices, place the assembly on a conductive sur­face such as aluminum foil, to prevent electrostatic charge buildup or exposure of the assembly.
3. Use only a grounded-tip soldering iron to solder or unsolder ESD devices.
4. Use only an anti-static solder removal device. Some solder removal devices not classified as "anti-static" can generate electrical charges sufficient to damage ESD devices.
5. Do not use freon-propelled chemicals. These can generate electrical charges sufficient to damage ESD devices.
6. Do not remove a replacement ESD device from its protective package until immediately before you are ready to install it. (Most replacement ESD devices are packaged with leads electrically shorted together by conductive foam, aluminum foil or comparable conductive materials).
7. Immediately before removing the protective material from the leads of a replacement ESD device, touch the protective material to the chassis or circuit assembly into which the device will by installed.
CAUTION : BE SURE NO POWER IS APPLIED TO THE CHASSIS OR CIRCUIT, AND OBSERVE ALL
OTHER SAFETY PRECAUTIONS.
8. Minimize bodily motions when handing unpackaged replacement ESD devices. (Otherwise harmless motion such as the brushing together of your clothes fabric or the lifting of your foot from a carpeted floor can gen­erate static electricity sufficient to damage an ESD device).
CAUTION. GRAPHIC SYMBOLS

SPECIFICATIONS
MP3/WMA Disc compatibility with this unit is limited as follows:
1. Sampling Frequency / 8 - 48kHz (MP3) 22.05 - 48kHz (WMA)
2. Bit rate / within 8 - 320kbps (include VBR) (MP3) 32 -320kbps (WMA)
3. CD-R/CD-RW physical format should be ISO 9660
4. If you record MP3/WMA files using software which cannot create a FILE SYSTEM, for example
Direct-CD etc., it will not be possible to playback MP3/WMA files. We recommend that you useEasy-CD Creator which can create an ISO9660 file system.
Customers should also note that permission is required in order to download MP3/WMA files and music from the Internet. Our company has no right to grant such permission. Permission should always be sought from the copyright owner.

OTI6888 (USB Host Controller)
1) GENERAL DESCRIPTION
OTi-6889 is the USB mini host controller with popular compressed media format bit-stream interface, such as MP3, WMA. The controller embedded the USB 1.1 host/device function; the function provides the ability that can be connected to the USB device and PC via USB port. The user may store the MP3/WMA songs in the USB mass storage device and play them through the OTi-6889 bit-stream interface. The PC-LINK function is also embedded in the OTi-6889; this function gives the easy way to connect and play MP3/WMA songs from the PC.The user may connect the PC and OTi-6889 with the PC-LINK function and control the play/pause, stop, FF, FR and volume up/down at the PC side. OTi-6889 is the high­ly functional integrated controller; to minimum the external component requirement, the high performance RISC, regulator, PLL, USB function, UART, I2C and GPIO were high-density built in the con-
troller.
2) FEATURES
The USB host controller conforms to Full-speed (12Mb/s) USB Specification, Version 1.1.
Built-in SD/MMC card interface which conforms to SD specification V1.1 and MMC specification V4.1
(Only available in LQFP-128 package).
Supports the USB storage device (Version 1.1 or 2.0) with mass storage class.
Integrated USB transceiver and Phase Lock Loop (PLL).
Supports Internal System Programming (ISP) function for external program flash ROM.
Supports USB audio PC-Link function.
Integrated RISC micro-controller; high-performance RISC architecture with single cycle per instruction.
I
2
C, I2S, general purpose serial interface and GPIOs for application customization.
12MHz and 18.432MHz external crystal for USB application and PC-LINK function.
3.3 V power operation.
128k Bytes embedded program ROM.
Supports File System, includes FAT12, FAT16 and FAT32.
Small form factor - standard 80-pin and 128-pin LQFP package.
