12、 an electric shock. 2. When replacing parts, use only manufacturers recommended components for safety. 3. Check the condition of the power cord. Replace if wear or damage is evident. 4. After servicing, be sure to restore the lead dress, insulation barriers, insulation papers, shields, etc. 5. Befor

13、e returning the serviced equipment to the customer, be sure to make the following insulation resistance test to prevent the customer from being exposed to a shock hazard. lInsulation Resistance Test 1. Unplug the power cord and short the two prongs of the plug with a jumper wire. 2. Turn on the powe

14、r switch. 3. Measure the resistance value with ohmmeter between the jumper AC plug and each exposed metal cabinet part, such as screw heads, antenna, control shafts, handle brackets, etc. Equipment with antenna terminals should read between 3M and 5.2M toall exposed parts*. (Fig 1) Equipment without

15、 antenna terminals should read approximately infinity to all exposed parts. (Fig 2) *Note: Some exposed parts may be isolated from the chassis by design. These will read infinity. 4. If the measurement is outside the specified limits, there is a possibility of a shock hazard. The equipment should be

16、 repaired and rechecked before it is returned to the customer. pagina 1 van 3 29-11-2012file:/H:/Audio%20nieuw/T/Technics/viewing/SGML_VIEW_DATA/NA/SA-DA15.

DO NOT SHORT-CIRCUIT DIRECTLY (with

18、a screw driver blade, for instance), as this may destroy solid state devices. After repairs are completed, restore power gradually using a variac, to avoid over current. Current consumption at AC 120 V, 60 Hz in NO SIGNAL mode should be 4501000 mA. TOP PREVIOUS NEXT pagina 1 van 1 29-11-2012file:/H:

The function of this circui

20、try is to prevent circuitry damage if, for example, the positive and negative speaker connection wires are “shorted”, or if speaker systems with an impedance less than the indicated rated impedance ofthe amplifier are used. If this occurs, follow the procedure outlines below: 1. Turn off the power.

21、2. Determine the cause of the problem and correct it. 3. Turn on the power once again after one minute. Note: When the protection circuitry functions, the unit will not operate unless the power is first turned off and then on again. TOP PREVIOUS NEXT pagina 1 van 1 29-11-2012file:/H:/Audio%20nieuw/T
