NOTES ON HANDLING THE OPTICAL PICK-
UP BLOCK OR BASE UNIT
UP BLOCK OR BASE UNIT
The laser diode in the optical pick-up block may suffer electro-
static breakdown because of the potential difference generated by
the charged electrostatic load, etc. on clothing and the human body.
During repair, pay attention to electrostatic breakdown and also
use the procedure in the printed matter which is included in the
repair parts.
The flexible board is easily damaged and should be handled with
care.

NOTES ON LASER DIODE EMISSION CHECK
The laser beam on this model is concentrated so as to be focused
on the disc reflective surface by the objective lens in the optical
pick-up block. Therefore, when checking the laser diode emis-
sion, observe from more than 30 cm away from the objective lens.

CHECKING THE VERSION BEFORE REPLACEMENT OF
FLASH MEMORY (IC1030 ON MAIN BOARD)
FLASH MEMORY (IC1030 ON MAIN BOARD)
This set is available with two types, Initial Lot type and User Up-
grade type, depending on the software version used in the micro-
computer.
If the Flash Memory (IC1030 on MAIN board) or mounted MAIN
board was replaced, the work (*1) required after parts replace-
ment is different according to the type. Therefore, before parts
replacement, check the type of set, and then perform the work
(*1) necessary for that type. However, if the version check is im-
possible because of a trouble in the set, handle it as a User Up-
grade type.
*1: For the work required after parts replacement, refer to “Setup

Cautions
• This unit is designed for negative ground 12 V
DC operation only.
• Do not get the wires under a screw, or caught
in moving parts (e.g. seat railing).
• Before making connections, turn the car
ignition off to avoid short circuits.
• Connect the yellow and red power input leads
only after all other leads have been connected.
• Run all ground wires to a common ground
point.
• Be sure to insulate any loose unconnected
wires with electrical tape for safety.
• The use of optical instruments with this
product will increase eye hazard.
