FR-N3X SERVICE PROCEDURES
PROTECTION OF EYES FROM LASER BEAM DURING SERVICING
This set employs a laser. Therefore, be sure to follow carefully the instructions below when servicing.
Laser Diode Properties
Material: GaAS/GaALAs Wavelength: 780nm Laser output: max. 0.5mW* Emission Duration: continuous *This output is the value measured at a distance about 1.8mm from the objective lens surface on the Optical Pick-up Block.
WARNING!! SERVICE WARNING : DO NOT APPROACH THE LASER EXIT WITH THE EYE TOO CLOSELY. IN CASE IT IS NECESSARY TO CONFIRM LASER BEAM EMISSION, BE SURE TO OBSERVE FROM A DISTANCE OF MORE THAN 30cm FROM THE SURFACE OF THE OBJECTIVE LENS ON THE OPTICAL PICK-UP BLOCK.
LASER WARNING LABEL
The label shown below are affixed.
1. Warning label
2. Class 1 label
"CLASS 1 LASER PRODUCT"
LUOKAN 1 LASERLAITE KLASS 1 LASER APPARAT
SERVICE PROCEDURE
1. Replacing the fuses
This symbol located near the fuse indicates that the fuse used is show operating type, For continued protection against fire hazard, replace with same type fuse , For fuse rating, refer to the marking adjest to the symbol. Ce symbole indique que le fusible utilise est e lent. Pour une protection permanente, n'utiliser que des fusibles de meme type. Ce demier est indique la qu le present symbol est apposre. REF.NO.

FR-N3X DISASSEMBLING PROCEDURES (CD) -1
CD MECHANISM : REPLACEMENT OF OPTICAL PICKUP
The laser diode in the optical pickup block is so sensitive to static electricity, surge current and etc. That the components are liable to be broken down or its reliability remarkably deteriorated. During repair, carefully take the following precautions. When you remove CD mechanism, please be sure to perform optical pickup short-circuit before removing the connection line between an optical pickup and CD & microcomputer board (NADG-7557).
1
In exchanging optical pickups, remove the plate(s) at the bottom of the set first. And jumper wire in CD connector board is short-circuited with solder.
2
1. Remove the MD mechanism and front section from main chassis. 2. Remove the bracket (CD). Remove the four screws which fix CD mechanism.

Continue at 6-2(Adjustment of laser power) and do this work.
(1) Turns MULTI JOG, and select the LDPWR CHECK mode. (2) Press MULTI JOG. (3) Checks that reading of laser power meter is 0.92mW. (4) Press MULTI JOG. (5) Checks that reading of laser power meter is 7.2 mV. (6) Measure a laser current value (V) in digital bolt meter. Calculate laser current value (I) and compare with the display of the label(Id) on pickup unit. (Fig-1) I (mA)= V / 1(ohm) Check that the laser current value(I) is Id(mA) 10%. Notes The current value may be large if the pickup has deteriorated. (7) Press the EDIT/CLEAR/NO button after check. (8) Press EJECT and takes out the optical sensor. (9) Remove the digital volt meter from JIG.
