YMC-700/YMC-500
This product contains chemicals known to the State of California to cause cancer, or birth defects or other reproductive
harm.
DO NOT PLACE SOLDER, ELECTRICAL/ELECTRONIC OR PLASTIC COMPONENTS IN YOUR MOUTH FOR ANY REASON
WHATSOEVER!
Avoid prolonged, unprotected contact between solder and your skin! When soldering, do not inhale solder fumes or
expose eyes to solder/flux vapor!
If you come in contact with solder or components located inside the enclosure of this product, wash your hands before
handling food.
1. Critical Components Information
Components having special characteristics are marked ⚠and
must be replaced with parts having specifications equal to those
originally installed.
2. Leakage Current Measurement (For 120V Models Only)
When service has been completed, it is imperative to verify
that all exposed conductive surfaces are properly insulated
from supply circuits.
• Meter impedance should be equivalent to 1500 ohms shunted
by 0.15 μF.
For U model
“CAUTION”
“F1: FOR CONTINUED PROTECTION AGAINST RISK OF FIRE, REPLACE ONLY WITH SAME TYPE 5A, 125V
FUSE.”
For C model
CAUTION
F1: REPLACE WITH SAME TYPE 5A, 125V FUSE.
ATTENTION
F1: UTILISER UN FUSIBLE DE RECHANGE DE MÉME TYPE DE 5A, 125V.
All of the P.C.B.s installed in this unit and solder joints are soldered using the lead free solder.
Among some types of lead free solder currently available, it is recommended to use one of the following types for the
repair work.
• Sn + Ag + Cu (tin + silver + copper)
• Sn + Cu (tin + copper)
• Sn + Zn + Bi (tin + zinc + bismuth)
Caution:
As the melting point temperature of the lead free solder is about 30°C to 40°C (50°F to 70°F) higher than that of the lead
solder, be sure to use a soldering iron suitable to each solder.
■TO SERVICE PERSONNEL
• Leakage current must not exceed 0.5mA.
• Be sure to test for leakage with the AC plug in both polarities.

■UPDATING FIRMWARE
Note) The user memories (sound field parameters, system memory, tuner presetting, etc.) are preserved even after the
firmware is written.
When replacing the following parts, be sure to write the latest firmware.
DIGITAL P.C.B.
IC344 (Microprocessor FLASH ROM) of DIGITAL P.C.B.
IC373 (DSP FLASH ROM) of DIGITAL P.C.B.
●Required Tools
• USB storage device
• Firmware (YMC700xxxx.bin, YMC500xxxx.bin)
• TV with HDMI input terminal (for Confirmation of firmware version and checksum)
• HDMI cable (for Confirmation of firmware version and checksum)
●Preparation
1. Download the latest firmware from the specified download source to PC.
2. Copy the latest firmware from the PC to the root folder of the USB storage device.
