No. 4418 102012 RadioFans.CN 收音机爱 好者资料库 CR-555/555DAB/N755 Service Procedures - 1 WARNING WARNING: TO REDUCE THE RISK OF FIRE OR ELECTRIC SHOCK, DO NOT EXPOSE THIS APPLIANCE

2、TO RAIN OR MOISTURE. CAUTION: TO REDUCE THE RISK OF ELECTRIC SHOCK, DO NOT REMOVE COVER (OR BACK). NO USER-SERVICEABLE PARTS INSIDE. REFER SERVICING TO QUALIFIED SERVICE PERSONNEL. The lightning flash with arrowhead symbol, within an equilateral triangle, is intended to alert the user to the presenc

3、e of uninsulated “dangerous voltage” within the products enclosure that may be of sufficient magnitude to constitute a risk of electric shock to persons. The exclamation point within an equilateral triangle is intended to alert the user to the presence of important operating and maintenance (servici

4、ng) instructions in the literature accompanying the appliance. WARNING RISK OF ELECTRIC SHOCK DO NOT OPEN RISQUE DE CHOC ELECTRIQUE NE PAS OUVRIR AVIS This unit contains a semiconductor laser system and is classified as a “CLASS 1 LASER PRODUCT”. So, to use this model properly, read this Instruction

5、 Manual carefully. In case of any trouble, please contact the store where you purchased the unit. To prevent being exposed to the laser beam, do not try to open the enclosure. CAUTION: VISIBLE LASER RADIATION WHEN OPEN AND INTERLOCK FAILED OR DEFEATED. DO NOT STARE INTO BEAM. CAUTION: THIS PRODUCT U

6、TILIZES A LASER. USE OF CONTROLS OR ADJUSTMENTS OR PERFORMANCE OF PROCEDURES OTHER THAN THOSE SPECIFIED HEREIN MAY RESULT IN HAZARDOUS RADIATION EXPOSURE. The label on the right is applied on the rear panel except for USA and Canadian models. 1. This unit is a CLASS 1 LASER PRODUCT and employs a las

7、er inside the cabinet. 2. To prevent the laser from being exposed, do not remove the cover. Refer servicing to qualified personnel. “CLASS 1 LASER PRODUCT” LASER CAUTION LASER DIODE Never look at the laser light beam through the objective lens. The visible laser beam may harm the human eye. Use an a

8、ppropriate viewer or TV camera to observe the laser beam. Any laser diode will be damaged by a large current or pulse. Avoid current surges and electrostatic discharges. Safety grounding of the human body and all measuring equipment, jigs and tools is absolutely necessary. The use of a grounding mat

9、 on the workbench and floor is necessary. Even a small electrostatic discharge from the human body may destroy the laser diode instantaneously or reduce its life time. The pins of the laser diode may be shorted at the factory by a solder bridge at the FPC for protection during transportation and sto

10、rage of the unit. If this is the case, open the short circuit (accessible from the bottom side of the module) quickly with grounded soldering iron (less than 300C). The damage of the diode might be indicated by an increase of the laser current. RadioFans.CN 收音机爱 好者资料库 CR-555/555DAB/N755 Service Proc
