1. Cautionary instructions in handling the assy
(Safety instructions)
Optical pickup
The laser beam used in the pickup is classified as "class 2".
Exposing your eyes or skin to the beam is harmful. Take care
not to do so.
(Caution against static electricity and leakage voltage)
Ground securely the work tables, tools, fixtures, soldering irons
(including those made of ceramic) and measuring instruments
used in the production lines and inspection departments that
handle loaders. The workers shall also be grounded.
(Cautionary instructions in handling)
Do not touch the object lens when handling a loader, or the lens
will be stained, resulting in inadequate playability.
There is no power supply protection circuit provided for this
product or adjustment/inspection device. Short-circuiting may
lead to fire or damage.
Take care so as to protect from exposure to water, the entry of
metallic pieces or dew condensation.
In particular, a strong magnet adjacent to the pickup will not
only get inoperative but can damage the pickup if a small metallic
piece, such as a screw or swarm, enters.
The loader edge can cause injury if inadvertently handled.
Do not touch a rotating disk, or injury may result.
This product is a precision device. Handle carefully.
A shock or dropping will cause misalignment or destruction. If it
should occur, refer to clause 2.
This product is so designed as to endure an initial shock
equivalent to a drop from a height of approx. 90 cm under the
packed condition.
After the initial shock, the resistivity will still remain at a level of
50 to 60 G, but the mechanical robustness will weaken.
Do not place in a dusty location.
The entry and deposition of dirt into or on the pickup lens or
moving section will cause malfunction or degradation.
DVD MECHANISM REPLACEMENT
(Connectors)
Do not connect or disconnect while power is on.
Connecting or disconnecting signal wires or the main power cord
when the power is on may destruct the unit or fixture.
When connecting, push all the way in securely.
An insufficient insertion may cause a bad contact, leading to an
erroneous operation.
Do not connect or disconnect roughly by an excessively strong
force, or a broken wire or bad contact may result.
Semiconductors are connected. Do not touch connector
terminals directly.
If the worker is grounded, there is nothing to worry about static
electricity, but the rust on the connector terminal surface caused
by the touch may result in bad contact.
(Caution)
Before disconnecting FFC
cable, make it "SHORT" as
shown left.
After connecting FFC
cable,make it "OPEN" as
shownleft.
(Power source)
The power source need be good in quality (free from
instantaneous interruptions or noises).
A low quality power source may well cause malfunction.
(Storage)
Do not place or store in a dusty place or a place where dew
condensation is possible.
The entry and deposition of dirt or dust into or on the pickup lens
or moving section will cause malfunction or degradation.
Also, dew condensation causes rust; the rust penetrate into the
precision part of a pickup, causing malfunction, or degrading
the optical quality of the internal lens and reflector, which also
leads to malfunction.

SERVICE MODE
B. How to enter Service Mode.
You can enter Service Mode in any one of the following ways (1 to 3).
1. Using the buttons on the main unit
Immediately (within one second) after pushing both STOP and POWER buttons simultaneously, push PREV button.
A. Market / Region SETUP
In the initial condition for this model, Market and Region
information are undefined.
In the following cases, be sure to set up Market/Region.
1. When updating the system using CD-R
(Part code : 0PRADC7114--AJ).
2. When replacing a DVD substrate.
While Market/Region information are undefined, the message
"Region Undefined" is displayed on the screen.
NOTE: Even if the condition is not under 1 or 2 above, if the
message "Region Undefined" is displayed, be sure to set up
Market/Region.
2. Pushing the covered key located beneath Book Mark key on RB-
1500 or REM-S1500.
3. Simultaneously pushing both Shift key and ON SCREEN key on
PB-SL20.

SERVICE MODE
D. IMPORTANT NOTE
1. Once the "Market/Region" settings are written into EEPROM (IC801) on the DVD substrate, they cannot be reset.
(However, updating the system using CD-R enables you to make new settings.)
2. While the Internal Setup screen is displayed, pushing the Power button enables you to terminate the operations without
making any settings.
HOW TO LOAD SOFTWARE FOR MPEG P.W.BOARD
1. Power on, then open tray.
2. It take on CD-ROM for UPDATE software to the tray, and tray close.
3. Display " UP DATE" in the TV screen.
4. For the time being, tray open and FL display remain "UP DATE".
5. When software loading finished, FL display "STANDBY".
6. Next, set up market code and region code by "SERVICE MODE"
CD-ROM part code is "0PRADC7114--AJ".
