5、-assemblies of this product can contain opto-electronic devices. As long as these devices comply with Class I of laser or LED products according to EN 60825-1:1994, they will not be expressly marked on the product. If a special design should be covered by a higher class of this standard, the device

6、concerned will be marked directly on the assembly or sub-assembly in accordance with the above standard. A1First Aid In Case of Electric Shock:Separate the person as quickly as possible from the electric power source: By switching off the equipment, By unplugging or disconnecting the mains cable, or

7、 By pushing the person away from the power source, using dry, insulating material (such as wood or plastic). After having suffered an electric shock, always consult a doctor. Warning!Do not touch the person or his clothing before the power is turned off, otherwise you stand the risk of suffering an

8、electric shock as well! If the Person is Unconscious: Lay the person down Turn him to one side Check the pulse Reanimate the person if respiration is poor Call for a doctor immediately. CLASS I LASER PRODUCT CLASS I LED PRODUCT RadioFans.CN 收音机爱 好者资料库 Installation/Maintenance/ESD II BGeneral Install

9、ation Instructions Please consider besides these general instructions also any product-specific instructions in the “Installation” chapter of this manual. B1Unpacking Check the equipment for any transport damage. If the unit is mechanically damaged, if liquids have been spilled or if objects have fa

10、llen into the unit, it must not be connected to the AC power outlet, or it must be immediately disconnected by unplugging the power cable. Repair must only be per- formed by trained personnel in accordance with the applicable regulations. B2Installation Site Install the unit in a place where the fol

11、lowing conditions are met: The temperature and the relative humidity of the environment must be within the specified limits during operation of the unit. Relevant values are the ones at the air inlets of the unit. Condensation must be avoided. If the unit is installed in a location with large variat

12、ion of ambient temperature (e.g. in an OB-van), appropriate precautions must be taken before and after operation (for details on this subject, refer to Appendix 1). Unobstructed air flow is essential for proper operation. Air vents of the unit are a functional part of the design and must not be bloc

13、ked in any way during operation (e.g. by objects placed upon them, placement of the unit on a soft surface, or installation of the unit within a rack or piece of furniture). The unit must not be heated up by external sources of heat radiation (sunlight, spot lights). B3Earthing and Power Supply Eart

14、hing of units with mains supply (class I equipment) is performed via the protective earth (PE) conductor integrated in the mains cable. Units with battery operation ( 60 V, class III equipment) must be earthed sepa- rately. Earthing the unit is one of the measures for protection against electrical s

15、hock hazard (dangerous body currents). Hazardous voltage may not only be caused by a defective power supply insulation, but may also be intro- duced by the connected audio or control cables. If the unit is installed with one or several external connections, its earthing must be provided during opera

16、tion as well as while the unit is not operated. If the earthing connection can be interrupted, for example, by unplugging the mains plug of an external power supply unit, an additional, permanent earthing connection must be installed using the provided earth terminal. Avoid ground loops (hum loops)

17、by keeping the loop surface as small as possible (by consequently guiding the earth conductors in a narrow, paral- lel way), and reduce the noise current flowing through the loop by inserting an additional impedance (common-mode choke). ESD/Repair III Class I Equipment (Mains Operation) Should the e

18、quipment be delivered without a matching mains cable, the latter has to be prepared by a trained person using the attached female plug (IEC320/C13 or IEC320/C19) with respect to the applicable regulations in your country. Before connecting the equipment to the AC power outlet, check that the local l

19、ine voltage matches the equipment rating (voltage, frequency) within the admissible tolerance. The equipment fuses must be rated in accordance with the specifications on the equipment. Equipment supplied with a 3-pole appliance inlet (protection conforming to class I equipment) must be connected to

20、a 3-pole AC power outlet so that the equipment cabinet is connected to the protective earth. For information on mains cable strain relief please refer to Appendix 2.

21、ite Green/YellowPE (Protective Earth)Green (or Green/Yellow) Class III Equipment (Battery Operation up to 60 VDC) Equipment of this protection class must be earthed using the provided earth terminal, if one or more external signals are connected to the unit (see ex- planation at the beginning of thi

22、s paragraph). B4Electromagnetic Compatibility (EMC) The unit conforms to the protection requirements relevant to electromag- netic phenomena that are listed in guidelines 89/336/EC and FCC, part 15. The electromagnetic interference generated by the unit is limited in such a way that other equipment

23、and systems can be operated normally. The unit is adequately protected against electromagnetic interference so that it can operate properly. The unit has been tested and conforms to the EMC standards of the speci- fied electromagnetic environment, as listed in the following declaration. The limits o

24、f these standards ensure protection of the environment and cor- responding noise immunity of the equipment with appropriate probability. However, a professional installation and integration within the system are imperative prerequisites for operation without EMC problems. For this purpose, the follo

25、wing measures must be followed: Install the equipment in accordance with the operating instructions. Use the supplied accessories. In the system and in the vicinity where the equipment is installed, use only components (systems, equipment) that also fulfill the EMC stan- dards for the given environm

26、ent. Use a system grounding concept that satisfies the safety requirements (class I equipment must be connected with a protective ground conduc- Installation/Maintenance/ESD IV tor) and that also takes into consideration the EMC requirements. When deciding between radial, surface, or combined ground

27、ing, the advan- tages and disadvantages should be carefully evaluated in each case. Use shielded cables where shielding is specified. The connection of the shield to the corresponding connector terminal or housing should have a large surface and be corrosion-proof. Please note that a cable shield co

28、nnected only single-ended can act as a transmitting or receiving an- tenna within the corresponding frequency range. Avoid ground loops or reduce their adverse effects by keeping the loop surface as small as possible, and reduce the noise current flowing through the loop by inserting an additional i

29、mpedance (e.g. common- mode choke). Reduce electrostatic discharge (ESD) of persons by installing an appro- priate floor covering (e.g. a carpet with permanent electrostatic fila- ments) and by keeping the relative humidity above 30%. Further meas- ures (e.g. conducting floor) are usually unnecessar

30、y and only effective if used together with corresponding personal equipment. When using equipment with touch-sensitive operator controls, please take care that the surrounding building structure allows for sufficient capacitive coupling of the operator. This coupling can be improved by an additional

31、, conducting surface in the operators area, connected to the equipment housing (e.g. metal foil underneath the floor covering, carpet with conductive backing). CMaintenance All air vents and openings for operating elements (faders, rotary knobs) must be checked on a regular basis, and cleaned in cas

32、e of dust accumula- tion. For cleaning, a soft paint-brush or a vacuum cleaner is recommended. Cleaning the surfaces of the unit is performed with a soft, dry cloth or a soft brush. Persistent contamination can be treated with a cloth that is slightly humidi- fied with a mild cleaning solution (soap

33、-suds). For cleaning display windows, commercially available computer/TV screen cleaners are suited. Use only a slightly damp (never wet) cloth. Never use any solvents for cleaning the exterior of the unit! Liquids must never be sprayed or poured on directly! For equipment-specific maintenance infor

34、mation please refer to the corre- sponding chapter in the Operating and Service Instructions manuals. DElectrostatic Discharge during Maintenance and Repair Caution: Observe the precautions for handling devices sensitive to electrostatic dis- charge! Many semiconductor components are sensitive to el

35、ectrostatic discharge (ESD). The life-span of assemblies containing such components can be drastically reduced by improper handling during maintenance and repair work. Please observe the following rules when handling ESD sensitive components: ESD sensitive components should only be stored and transp

36、orted in the packing material specifically provided for this purpose. When performing a repair by replacing complete assemblies, the re- moved assembly must be sent back to the supplier in the same packing ESD/Repair V material in which the replacement assembly was shipped. If this should not be the

37、 case, any claim for a possible refund will be null and void. Unpacked ESD sensitive components should only be handled in ESD protected areas (EPA, e.g. area for field service, repair or service bench) and only be touched by persons who wear a wristlet that is connected to the ground potential of th

38、e repair or service bench by a series resistor. The equipment to be repaired or serviced as well as all tools and electri- cally semi-conducting work, storage, and floor mats should also be con- nected to this ground potential. The terminals of ESD sensitive components must not come in uncon- trolle

39、d contact with electrostatically chargeable (voltage puncture) or metallic surfaces (discharge shock hazard). To prevent undefined transient stress of the components and possible damage due to inadmissible voltages or compensation currents, electri- cal connections should only be established or sepa

40、rated when the equipment is switched off and after any capacitor charges have decayed. ERepair Removal of housing parts, shields, etc. exposes energized parts. For this reason the following precautions must be observed: Maintenance may only be performed by trained personnel in accordance with the ap

41、plicable regulations. The equipment must be switched off and disconnected from the AC power outlet before any housing parts are removed. Even if the equipment is disconnected from the power outlet, parts with hazardous charges (e.g. capacitors, picture tubes) must not be touched until they have been

42、 properly discharged. Do not touch hot components (power semiconductors, heat sinks, etc.) before they have cooled off. If maintenance is performed on a unit that is opened and switched on, no un-insulated circuit components and metallic semiconductor housings must be touched, neither with your bare

43、 hands nor with un-insulated tools. Certain components pose additional hazards: Explosion hazard from lithium batteries, electrolytic capacitors and power semiconductors (watch the components polarity. Do not short battery terminals. Replace batteries only by the same type). Implosion hazard from ev

44、acuated display units. Radiation hazard from laser units (non-ionizing), picture tubes (ioniz- ing). Caustic effect of display units (LCD) and components containing liquid electrolyte. Such components should only be handled by trained personnel who are properly protected (e.g. safety goggles, gloves

45、). Repair/Disposal VI E1SMD Components Studer has no commercially available SMD components in stock for serv- ice purposes. For repair, the corresponding devices have to be purchased locally. The specifications of special components can be found in the serv- ice manual. SMD components should only be

46、 replaced by skilled specialists using ap- propriate tools. No warranty claims will be accepted for circuit boards that have been damaged. Proper and improper SMD soldering joints are illus- trated below. FDisposal Disposal of Packing MaterialsThe packing materials have been selected with environmen

47、tal and disposal issues in mind. All packing material can be recycled. Recycling packing saves raw materials and reduces the volume of waste. If you need to dispose of the transport packing materials, please try to use recyclable means. Disposal of Used EquipmentUsed equipment contains valuable raw

48、materials as well as materials that must be disposed of professionally. Please return your used equipment via an authorized specialist dealer or via the public waste disposal system, en- suring any material that can be recycled is. Please take care that your used equipment cannot be abused. To avoid

49、 abuse, delete sensitive data from any data storage media. After having dis- connected your used equipment from the mains supply, make sure that the mains connector and the mains cable are made useless. 32 Dismounting MountingExamples Solder SMD Component Copper Track Adhesive Soldering Iron Desoldering Iron Desolder Wick Heat and RemoveCleaning Solder 0.5.0.8 mm Heating Time 3 s per Side Soldering Iron Desolder Wick 1 32 1 PCB Conformity VII GDeclarations of Conformity G1Class A Equipment - FCC Notice This equipment has been tested and
