SAFETY INSTRUCTION
WARNING: BEFORE SERVICING THIS CHASSIS, READ THE "SAFETY PRECAUTION" AND "PRODUCT
SAFETY NOTICE" INSTRUCTIONS BELOW.
Safety Precaution
WARNING: SERVICING SHOULD NOT BE ATTEMPTED BY ANYONE UNFAMILIAR WITH THE
NECESSARY PRECAUTIONS ON THIS RECEIVER. THE FOLLOWING ARE THE NECESSARY
PRECAUTIONS TO BE OBSERVED BEFORE SERVICING THIS CHASSIS.
1. An isolation transformer should be connected in the power line between the receiver
and the AC line before any service is performed on the receiver.
2. Always disconnect the power plug before any disassembling of the product. It may
result in electrical shock.
3. When replacing a chassis in the cabinet, always be certain that all the protective
devices are put back in place, such as nonmetallic control knobs, insulating covers,
shields, isolation resistor-capacitor network, etc.
4. Always keep tools, components of the product, etc away from the children, These
items may cause injury to children.
5. Depending on the model, use an isolation transformer or wear suitable gloves when
servicing with the power on, and disconnect the power plug to avoid electrical shock
when replacing parts. In some cases, alternating current is also impressed in the
chassis, so electrical shock is possible if the chassis is contacted with the power on.
6. Always use the replacement parts specified for the particular model when making
repairs. The parts used in products require special safety characteristics such as
inflammability, voltage resistance, etc. therefore, use only replacement parts that have
these same characteristics. Use only the specified parts when the mark is indicated
in the circuit diagram or parts list.
7. Parts mounting and routing dressing of wirings should be the same as that used
originally. For safety purposes, insulating materials such as isolation tube or tape are
sometimes used and printed circuit boards are sometimes mounted floating. Also
make sure that wirings is routed and clamped to avoid parts that generate heat and
which use high voltage. Always follow the manufactured wiring routes / dressings.
Page 6
8. Always ensure that all internal wirings are in accordance before re-assembling the
external casing after a repairing completed. Do not allow internal wiring to be pinched
by cabinets, panels, etc. Any error in reassembly or wiring can result in electrical
leakage, flame, etc., and may be hazardous.
9. NEVER remodel the product in any way. Remodeling can result in improper operation,
malfunction, or electrical leakage and flame, which may be hazardous.
10. Touch current check. (After completing the work, measure touch current to prevent an
electric shock.)
Plug the AC cord directly into the AC outlet. Do NOT use an isolation transformer for
this check.
Connect a measuring network for touch currents between each exposed metallic part
on the set and a good earth ground such as a water pipe.

Copy To USB
There are two steps and both are independent from each other.
For welcome image downloading to USB, there should be DownloadWelcomeScreen.mb82 file in USB
ROOT.
Copy the updated welcome image to USB in directory “welcome_image” as “hotel_wel.png”
Copy NVRAM data (service list, preferences, etc.) to USB device. On Phonix platform, all nvram data
is stored in 8x32KB Flash files named as “nvblock_ ... .bin”. When Copy to USB is called, those files
are copied from TV to USB. Then they can be used for various purposes testing on another TV or
testing/debugging on observatory etc. Note that USB should be plugged before this operation.
A new folder will be created in the USB with every operation of “Copy To USB”. Folder names will
automatically increase like CLONE00001, CLONE00002, etc. (up to 99999)
Copy From USB
Firstly, you will see the directory list of your USB if it is connected. All operations will start after you
select one of this folders. The selected folder could also be the root folder. For Copy-From-USB
operation, there are two steps and both are independent from each other.
If there is file named “hotel_wel.png” in the folder “welcome_image” in the USB directory you selected,
it is copied to tv to use as welcome image. The selected directory can be the root or the one created
by user in the USB.
