Firmware Update Procedure
Updating by USB
The latest firmware can be downloaded to a USB Memory for updates.
Connecting to the USB Memory
(1) Prepared
# USB format: Prepare a USB memory formatted in FAT16 or FAT32.
3 Do not run the USB memory through a hub.
3 Do not connect a computer to the USB port of this unit using a USB cable.
# Do not use an extension cable when connecting the USB memory.
Unzip Download File
Unzip the downloaded file on your computer.
You can find "S500BT_USB_V**_**.fw" fole after unzipped. Copy that file to USB flash drive.
You have to put "S500BT_USB_V**_**.fw" file on root directly on USB flash drive(memory).
Insert the USB memory device in the USB port
Start the update
Turn on the power of this unit. Then, push "SETUP" and select.
(1) Select "General”
(2) Select "Firmware"
(3) Push "ENTER"
(4) Select "Yes", then, Push "ENTER"
Precautions for Updates ---
# Never remove the USB memory before the update is finished.
# Never turn off the power before an update is completed.
# It takes around about 35 minutes to complete the update even with a broadband connection.
Once an update is started, normal operations cannot be performed until it is completed.
The GUI menu settings and image adjustment settings of this unit may be initialized.
Take note of your settings beforehand and reconfigure them after the update.
ADJUSTMENT
Adjusting Idling Current
Required measurement equipment: DC Voltmeter
1. Preparation
(1) Avoid direct blow from an air conditioner or an electric fan and humidity should be moderate, and place the set at normal usage environment.
Temperature should be at 15 °C ~ 30 °C (59 °F ~ 86 °F).
(2) Presetting
# POWER (Power source switch) OFF
# SPEAKER (Speaker terminal) No load
(Do not connect speaker, dummy resistor, etc.)
2. Adjustment
(1) Remove the top cover and set VR510(FL), VR550(FR), VR530(C), VR520(SL), VR540(SR), on MAIN PCB at fully counterclockwise (c) position.
(2) Connect DC Voltmeter to test points (FRONT-Lch: CN510, FRONT-Rch: CN550, CENTER ch: CN530, SURROUNDLch: CN520, SURROUND-Rch: CN540).
(3) Connect the power cord to AC Line, and set the power switch to "ON".
(4) Presetting.
MASTER VOLUME : c minimum
SPEAKER (Speaker terminal) : No load
(Do not connect speaker, dummy resistor, etc.)
MODE : MCH STEREO
FUNCTION : CBL/SAT
(5) Within 2 minutes after the power on, turn VR510 clockwise (x) to adjust the TEST POINT voltage at 1.5mV ± 0.5mV DC.
(6) After 10 minutes from the preset above, turn VR510 to set the voltage to 2.0mV ± 0.5mV DC.
(7) Adjust the Variable Resistors of each channel(VR520-VR550) in the same way.
