DO NOT SHORT-CIRCUIT DIRECTLY (with a screwdriver blade, for instance), as this may destroy solid state devices. After repairsare completed, restore po

9、wer gradually using a variac, to avoid overcurrent. Current consumption at AC230V, 50Hz in NO SIGNAL mode should be less than 220mA. 2. Protection Circuitry The protection circuitry may have operated if either of the following conditions are noticed: - No sound is heard when the power is turned on.

10、- Sound stops during a performance. The function of this circuitry is to prevent circuitry damage if, for example, the positive and negative speaker connection wires are “shorted”, or if speaker systems with an 3 RadioFans.CN 收音机爱 好者资料库 impedance less than the indicated rated impedance ofthe amplifi

11、er are used. If this occurs, follow the procedure outlines below: 1. Turn off the power. 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 o

12、ff and then on again. 3. Accessories 4. Handling Precautions for Traverse Deck The laser diodes in the traverse deck (optical pickup) may break down due to potential difference caused by static electricity of clothes or human body. So, be careful of electrostatic breakdown during repair of the trave

13、rse deck (optical pickup). 4.1. Handling the traverse deck (optical pickup) 1. The traverse deck (optical pickup) is an extremely high-precision construction and must not be subjected to impact, excessive vibration, or other types of rough 4 handling. 2. In order to prevent static electricity damage

14、 to the laser diode, use a short pin or similar tool to short the optical pickups flexible circuit boards after they have been disconnected from the main circuit board. 3. Handle the flexible circuit boards with care; excessive force could cause them to be broken. 4. Do not turn the pre-set variable

15、 resistor (for adjustment of the laser power); it has been adjusted at the factory. (as shown in Fig.1 ) Fig.1 4.2. Grounding for electrostatic breakdown prevention 1. Human body grounding Use the anti-atatic wrist strap to discharge the static electricity from your body. 5 2. Work table grounding P

16、ut a conductive material (sheet) or steel sheet on the area where the optical pickup is placed, and ground the sheet. (sa shown in Fig.2 ) Fig.2 6 Caution: The static electricity of your clothes will not be grounded through the wrist strap. So, take care not to let your clothes touch the traverse de
