1、Service Manual Supplement Digital Master Recorder ADDA-2 PCB for Model D-25/D-30 RadioFans.CN 收音机爱 好者资料库 SAFETY INSTRUCTIONS Read instructions - All the safety and operating instruc- tions should be read before the appliance is operated. Retain instructions - The safety and operating instructions sh

2、ould be retained for future reference. Heed warnings - All warnings on the appliance and in the operating instructions should be adhered to. Follow instructions - All operating and use instructions should be followed. Water and Moisture - The appliance should not be used near water - for example, ne

3、ar a bathtub, washbowl, kitchen sink, laundry tub, in a wet basement, or near a swimming pool, and the like. Carts and Stands - The appliance should be used only with a cart or stand that is recommended by the manufac- turer. An appliance and cart combination should be moved with care. Quick stops,

4、excessive force, and uneven surfaces may cause the appliance and cart combination to over- turn. Wall or Ceiling Mounting - The appliance should be mounted to a wall or ceiling only as recommended by the manufacturer. Ventilation - The appliance should be situated so that its location or position do

5、es not interfere with its proper ven- tilation. For example, the appliance should not be situ- ated on a bed, sofa, rug, or similar surface that may block the ventilation openings; or, placed in a built-in installa- tion, such as a bookcase or cabinet that may impede the flow of air through the vent

6、ilation openings. Heat - The appliance should be situated away from heat sources such as radiators, heat registers, stoves, or other appliances (including amplifiers) that produce heat. Power Sources - The appliance should be connected to a power supply only of the type described in the operating in

7、structions or as marked on the appliance. Grounding or Polarization - The precautions that should be taken so that the grounding or polarization means of an appliance is not defeated. Power Cord Protection - Power supply cords should be routed so that they are not likely to be walked on or pinched b

8、y items placed upon or against them, paying particular attention to cords at plugs, convenience recep- tacles, and the point where they exit from the appliance. Cleaning - The appliance should be cleaned only as rec- ommended by the manufacturer. Nonuse Periods - The power cord of the appliance shou

9、ld be unplugged from the outlet when left unused for a long period of time. Object and Liquid Entry - Care should be taken so that objects do not fall and liquids are not spilled into the en- closure through openings. Damage requiring Service - The appliance should be ser- viced by qualified service

10、 personnel when: A. B. C. D. E. Servicing - The user should not attempt to service the ap- pliance beyond that described in the operating instruc- tions. All other servicing should be referred to qualified service personnel. REFER SERVICING TO QUALIFIED SERVICE PERSONNEL. CAUTION RISK OF ELECTRIC SH

CAUTION: ATTENTION: The exclamation point within an equilateral triangle is intended to alert the user to the presence of important operating and mainte- nance (servicing) instructions in the literature accompanying the appliance. The lightening

13、 flash with arrowhead symbol, within an equilateral triangle, is intended to alert the user to the presence of uninsulated “dangerous voltage” within the products en- closure that may be of sufficient magnitude to constitute a risk of electric shock to persons. “WARNING” “TO REDUCE THE RISK OF FIRE
