SAFETY INFORMATION
This product has been designed and manufactured according to FDA
regulations "title 21, CFR, chapter 1, subchapter J, based on the Radiation
Control for Health and Safety Act of 1968", and is classified as a class 1
laser product. There is no hazardous invisible laser radiation during
operation because invisible laser radiation emitted inside of this product
is completely confined in the protective housings.
The label required in this regulation is shown 1.
OCAUTION
USE OF CONTROLS OR ADJUSTMENT OR PERFORMANCE OF
PROCEDURES OTHER THAN THOSE SPECIFIED HEREIN MAY RESULT IN
HAZARDOUS RADIATION EXPOSURE.

3-3 ID Number and ID Data Setting
Entering the ID Number and ID Data for Players with
DVD-Audio Compatibility
It is necessary with a player with DVD-audio compatibility to set
an individual number (ID number) and ID data. If the number and
data are not set correctly with the following procedure, operations
in the future may not be guaranteed. You will find the ID number
to be set on the label on the Side Chassis R.
Important: If no white label is found on the Side Chassis R,
write down the specified ID number by checking it according to
"How to Confirm the ID Number" shown below.
The Input is Necessary When:
DVDM PCB ASSY is replaced.
Downloading FLASH-ROM is finished.
• "No ID Number" is displayed on the screen or FL display
immediately after the power is turned on or in Stop mode.
If "No ID DATA" is displayed, the ID data must be entered.
Creating ID Data Disc
Download an image file of ID data disc off the TEAC Service Web
Site and write it to a CD-R using a commercially available writing
tool.
Care should be taken over security for ID data.
ID Number
How to Input the ID Number and ID Data
Be sure to enter the ID number in Stop mode.
Use the remote control unit RC-627 for operations. Only
opening/closing of the tray are performed from the player.
1. To enter the input mode, press ESC + STEREO in a status with
no ID number set, such as after FLASH-ROM downloading.
2. As number input is enabled when the unit enters the input
mode, input the 9-digit ID number.
(The entered number is also displayed on the FL display.)
3. After inputting the number, press SEARCH to register the ID
number.
4. When the ID number has been registered, the unit enters the ID
data input mode. (The FL display indicates "NO ID DATA")
In this condition, place the ID data disc on the tray and close
the tray using the OPEN/CLOSE button on the player.
