PRECAUTIONS FOR USING LEAD-FREE SOLDER ...........3
• Use an AC voltmeter having with 5000 ohm per volt, or higher, sen-
sitivity or measure the AC voltage drop across the resistor.
• Connect the resistor connection to all exposed metal parts having a
return to the chassis (antenna, metal cabinet, screw heads, knobs
and control shafts, escutcheon, etc.) and measure the AC voltage
drop across the resistor.
All checks must be repeated with the AC cord plug connection
reversed. (If necessary, a nonpolarized adaptor plug must be used
only for the purpose of completing these checks.)
Any reading of 1.05 V peak (this corresponds to 0.7 mA peak AC.)
or more is excessive and indicates a potential shock hazard which
must be corrected before returning the monitor to the owner.

The use of a substitute replacement parts which do not have the same

PRECAUTIONS FOR USING LEAD-FREE SOLDER
■ Using lead-free wire solder
• When fixing the PWB soldered with the lead-free solder, apply lead-free wire solder. Repairing with conventional lead wire solder may cause damage or
accident due to cracks.
As the melting point of lead-free solder (Sn-Ag-Cu) is higher than the lead wire solder by 40 °C, we recommend you to use a dedicated soldering bit, if
you are not familiar with how to obtain lead-free wire solder or soldering bit, contact our service station or service branch in your area.
Soldering
• As the melting point of lead-free solder (Sn-Ag-Cu) is about 220 °C which is higher than the conventional lead solder by 40 °C, and as it has poor solder
wettability, you may be apt to keep the soldering bit in contact with the PWB for extended period of time. However, Since the land may be peeled off or
the maximum heat-resistance temperature of parts may be exceeded, remove the bit from the PWB as soon as you confirm the steady soldering
condition.
Lead-free solder contains more tin, and the end of the soldering bit may be easily corroded. Make sure to turn on and off the power of the bit as required.
If a different type of solder stays on the tip of the soldering bit, it is alloyed with lead-free solder. Clean the bit after every use of it.
When the tip of the soldering bit is blackened during use, file it with steel wool or fine sandpaper.
• Be careful when replacing parts with polarity indication on the PWB silk.

• Remove batteries as soon as they are worn out. Chemicals that leak from batteries come in contact with skin can cause a rash. If you find any chemical
leakage, wipe thoroughly with a cloth.
• The batteries supplied with this product may have a shorter life expectancy due to storage conditions.
• If you will not be using the remote control unit for an extended period of time, remove batteries from it.
• The batteries (batteries installed) shall not be exposed to excessive heat such as sunshine, fire or the like.
Using the Remote Control Unit

General Description
The AT1529 high-efficiency, DC/DC buck converter delivers up to 3.2A of output current. The device operates from an input voltage of 2.5V to 6V and
provides an output voltage from 0.8V to VIN, making the AT1529 ideal for on-board post-regulation applications.
The AT1529 operate at a fixed frequency of 1MHz with an efficiency of up to 94%. The high operating frequency minimizes the size of external
components. Internal soft-start control circuitry reduces inrush current. Short-circuit and thermal-overload protections improve design reliability.
The AT1529 are available in a space-saving SOP-8 and TDFN3X3-8 package.

2.3 U602(STA339BWTR)
General Description
The STA339BW is an integrated solution of digital audio processing, digital amplifier control, and FFX-power output stage, thereby creating a high-power
single-chip FFX® solution comprising high-quality, high-efficiency, all digital amplification.
STA339BW is based on FFX (fully flexible amplification) processor, a STMicroelectronics proprietary technology. FFX is the evolution and the enlargement
of the ST ternary technology: the new processor can be configured to work in ternary, binary, binary differential and phase shift PWM modulation schemes.
STA339BW contains the ternary, binary and binary differential implementations, a subset of the full capability of the FFX processor.

47
LC-32SV21L&LC-42SV31L
The STA339BW is part of the Sound Terminal™ family that provides full digital audio streaming to the speaker, offering cost effectiveness, low power
dissipation and sound enrichment.
The STA339BW power section consists of four independent half-bridges. These can be configured via digital control to operate in different modes. 2.1
channels can be provided by two half-bridges and a single full-bridge, providing up to 2 x 9 W + 1 x 20 W of power output. Two channels can be provided
by two full-bridges, providing up to 2 x 20 W of power. The IC can also be configured as 2.1 channels with 2 x 20 W provided by the device and external
power for FFX power drive.
Also provided in the STA339BW are a full assortment of digital processing features. This includes up to 8 programmable 28-bit biquads (EQ) per channel
and bass/treble tone control. Available presets enable a time-to-market advantage by substantially reducing the amount of software development needed
for certain functions. This includes audio preset volume loudness, preset volume curves and preset EQ settings. There are also new advanced AM radio
interference reduction modes. Dual band DRC dynamically equalizes the system to provide speaker linear frequency response regardless output power
level. This feature independently processes the two bands, controlling, dynamically, the output power level in each band and so providing a better sound
quality.
The serial audio data input interface accepts all possible formats, including the popular I2S format. Three channels of FFX processing are provided. This
high-quality conversion from PCM audio to FFX PWM switching waveform provides over 100 dB SNR and dynamic range.

2.5 U606(MAX9728AETC+)
General Description
The MAX9728A/MAX9728B stereo headphone amplifiers are designed for display and notebook applications or portable equipment where board space is
at a premium. These devices use a unique, patented DirectDrive™ architecture to produce a ground-referenced output from a single supply, eliminating
the need for large DC-blocking capacitors, saving cost, board space, and component height. The MAX9728A offers an externally adjustable gain, while the
MAX9728B has an internally preset gain of -1.5V/V. The MAX9728A/MAX9728B deliver up to 60mW per channel into a 32 load and have low 0.02%
THD+N. An 80dB at 1kHz power-supply rejection ratio (PSRR) allows these devices to operate from noisy digital supplies without an additional linear
regulator. Comprehensive clickand-pop circuitry suppresses audible clicks and pops on startup and shutdown.
The MAX9728A/MAX9728B operate from a single 4.5V to 5.5V supply, consume only 3.5mA of supply current, feature short-circuit and thermal-overload
protection, and are specified over the extended -40°C to +85°C temperature range. The devices are available in tiny 12-pin Thin QFN (3mm x 3mm x

General Description
These I²C-compatible electrically erasable programmable memory (EEPROM) devices are organized as 2048/1024/512/256/128 x 8 (M24C16, M24C08,
M24C04, M24C02 and M24C01).
In order to meet environmental requirements, ST offers these devices in ECOPACK® packages. ECOPACK® packages are Lead-free and RoHS
compliant.
ECOPACK is an ST trademark. ECOPACK specifications are available at: www.st.com.
I²C uses a two-wire serial interface, comprising a bidirectional data line and a clock line. The devices carry a built-in 4-bit Device Type Identifier code (1010)
2008-03-14
51
LC-32SV21L&LC-42SV31L
in accordance with the I²C bus definition.
The device behaves as a slave in the I²C protocol, with all memory operations synchronized by the serial clock. Read and Write operations are initiated by
a Start condition, generated by the bus master. The Start condition is followed by a device select code and Read/Write bit (RW), terminated by an
acknowledge bit.
When writing data to the memory, the device inserts an acknowledge bit during the 9th bit time, following the bus master’s 8-bit transmission. When data is
read by the bus master, the bus master acknowledges the receipt of the data byte in the same way. Data transfers are terminated by a Stop condition after
an Ack for Write, and after a NoAck for Read.
