9 SECTION PRECAUTION. Safety Precautions! Burrs formed during molding may be left over on some parts of the chassis. Therefore, pay attention to such burrs in the case of preforming repair of this system.! Please use enough caution not to see the beam directly or touch it in case of an adjustment or operation check. (No.MA<Rev.00>)-9

10 . Preventing static electricity Electrostatic discharge (ESD), which occurs when static electricity stored in the body, fabric, etc. is discharged, can destroy the laser diode in the traverse unit (optical pickup). Take care to prevent this when performing repairs... Grounding to prevent damage by static electricity Static electricity in the work area can destroy the optical pickup (laser diode) in devices such as laser products. Be careful to use proper grounding in the area where repairs are being performed. () Ground the workbench Ground the workbench by laying conductive material (such as a conductive sheet) or an iron plate over it before placing the traverse unit (optical pickup) on it. () Ground yourself Use an anti-static wrist strap to release any static electricity built up in your body. (caption) Anti-static wrist strap M Conductive material (conductive sheet) or iron plate () Handling the optical pickup In order to maintain quality during transport and before installation, both sides of the laser diode on the replacement optical pickup are shorted. After replacement, return the shorted parts to their original condition. (Refer to the text.) Do not use a tester to check the condition of the laser diode in the optical pickup. The tester's internal power source can easily destroy the laser diode.. Handling the traverse unit (optical pickup) () Do not subject the traverse unit (optical pickup) to strong shocks, as it is a sensitive, complex unit. () Cut off the shorted part of the flexible cable using nippers, etc. after replacing the optical pickup. For specific details, refer to the replacement procedure in the text. Remove the anti-static pin when replacing the traverse unit. Be careful not to take too long a time when attaching it to the connector. () Handle the flexible cable carefully as it may break when subjected to strong force. () It is not possible to adjust the semi-fixed resistor that adjusts the laser power. Do not turn it.. Attention when traverse unit is decomposed *Please refer to "Disassembly method" in the text for the pickup unit. Apply solder to the short land before the card wire is disconnected from the connector on the pickup unit. (If the card wire is disconnected without applying solder, the pickup may be destroyed by static electricity.) In the assembly, be sure to remove solder from the short land after connecting the card wire. Short land section Connector Pickup Traverse mechanism assembly Card wire -0 (No.MA<Rev.00>)

11 . Important for laser products.class LASER PRODUCT.CAUTION : (For U.S.A.) Visible and/or invisible class II laser radiation when open. Do not stare into beam. (Others) Visible and/or invisible class M laser radiation when open. Do not view directly with optical instruments..caution : Visible and/or invisible laser radiation when open and inter lock failed or defeated. Avoid direct exposure to beam..caution : This laser product uses visible and/or invisible laser radiation and is equipped with safety switches which prevent emission of radiation when the drawer is open and the safety interlocks have failed or are defeated. It is dangerous to defeat the safety switches..caution : If safety switches malfunction, the laser is able to function..caution : Use of controls, adjustments or performance of procedures other than those specified here in may result in hazardous radiation exposure.! Please use enough caution not to see the beam directly or touch it in case of an adjustment or operation check. REPRODUCTION AND POSITION OF LABELS and PRINT WARNING LABEL and PRINT (No.MA<Rev.00>)-

For FM dummy load, there is a loss of db between SSG output and antenna input. The loss of db need not be considered sincedirect reading of figures are applied in this working standard.. How to connect the extension cable for adjusting Caution: Be sure to attach the heat sink and rear bracket onto the power amplifier IC and regulator IC respectively, before supply the power. If voltage is applied without attaching these parts, the power amplifier IC and regulator IC will be destroyed by heat. Extension cable EXTSH00-P (No.MA<Rev.00>)-9
