SAFETY PRECAUTIONS The following check should be performed for the continued protection of the customer and service technician. LEAKAGE CURRENT CHECK Measure leakage cu

4、rrent to a known earth ground (water pipe, conduit, etc.) by connecting a leakage current tester such as Simpson Model 229-2 or equivalent between the earth ground and all exposed metal parts of the appliance (input/output terminals, screwheads, metal overlays, control shaft, etc.). Plug the AC line

5、 cord of the appliance directly into a 120V AC 60 Hz outlet and turn the AC power switch on. Any current measured must not exceed 0.5 mA. ANY MEASUREMENTS NOT WITHIN THE LIMITS OUTLINED ABOVE ARE INDICATIVE OF A POTENTIAL SHOCK HAZARD AND MUST BE CORRECTED BEFORE RETURNING THE APPLIANCE TO THE CUSTO

6、MER. 2. PRODUCT SAFETY NOTICE Many electrical and mechanical parts in the appliance have special safety related characteristics. These are often not evident from visual inspection nor the protection afforded by them necessarily can be obtained by using replacement components rated for voltage, watta

7、ge, etc. Replacement parts which have these special safety characteristics are identified in this Service Manual. Electrical components having such features are identified by marking with a on the schematics and on the parts list in this Service Manual. The use of a substitute replacement component

8、which does not have the same safety characteristics as the PIONEER recommended replacement one, shown in the parts list in this Service Manual, may create shock, fire, or other hazards. Product Safety is continuously under review and new instructions are issued from time to time. For the latest info

9、rmation, always consult the current PIONEER Service Manual. A subscription to, or additional copies of, PIONEER Service Manual may be obtained at a nominal charge from PIONEER. Leakage current tester Reading should not be above 0.5 mA Device under test Test all exposed metal surfaces Also test with

13、 for Good Servicing In this manual, procedures that must be performed during repairs are marked with the below symbol. Please be sure to confirm and follow these procedures. 1. Product safety Please conform to product regulations (such as safety and radiation regulations), and maintain a safe servic

14、ing environment by following the safety instructions described in this manual. 1 Use specified parts for repair. Use genuine parts. Be sure to use important parts for safety. 2 Do not perform modifications without proper instructions. Please follow the specified safety methods when modification(addi

15、tion/change of parts) is required due to interferences such as radio/TV interference and foreign noise. 3 Make sure the soldering of repaired locations is properly performed. When you solder while repairing, please be sure that there are no cold solder and other debris. Soldering should be finished

16、with the proper quantity. (Refer to the example) 4 Make sure the screws are tightly fastened. Please be sure that all screws are fastened, and that there are no loose screws. 5 Make sure each connectors are correctly inserted. Please be sure that all connectors are inserted, and that there are no im

17、perfect insertion. 6 Make sure the wiring cables are set to their original state. Please replace the wiring and cables to the original state after repairs. In addition, be sure that there are no pinched wires, etc. 7 Make sure screws and soldering scraps do not remain inside the product. Please chec

18、k that neither solder debris nor screws remain inside the product. 8 There should be no semi-broken wires, scratches, melting, etc. on the coating of the power cord. Damaged power cords may lead to fire accidents, so please be sure that there are no damages. If you find a damaged power cord, please

19、exchange it with a suitable one. 9 There should be no spark traces or similar marks on the power plug. When spark traces or similar marks are found on the power supply plug, please check the connection and advise on secure connections and suitable usage. Please exchange the power cord if necessary.

20、0 Safe environment should be secured during servicing. When you perform repairs, please pay attention to static electricity, furniture, household articles, etc. in order to prevent injuries. Please pay attention to your surroundings and repair safely. 2. Adjustments To keep the original performance

21、of the products, optimum adjustments and confirmation of characteristics within specification. Adjustments should be performed in accordance with the procedures/instructions described in this manual. 4. Cleaning For parts that require cleaning, such as optical pickups, tape deck heads, lenses and mi

22、rrors used in projection monitors, proper cleaning should be performed to restore their performances. 3. Lubricants, Glues, and Replacement parts Use grease and adhesives that are equal to the specified substance. Make sure the proper amount is applied. 5. Shipping mode and Shipping screws To protec

23、t products from damages or failures during transit, the shipping mode should be set or the shipping screws should be installed before shipment. Please be sure to follow this method especially if it is specified in this manual. RadioFans.CN 收音机爱 好者资料库 DJM-400 4 1234 1234 C D F A B E CONTENTS 1. SPECI
