SAFETY PRECAUTIONS

The following check should be performed for the continued protection of the customer and service technician.

LEAKAGE CURRENT CHECK

Before returning the unit to the customer, make sure you make either (1) a leakage current check or (2) a line to chassis resistance check. If the leakage current exceeds 0.5 milliamps, or if the resistance from chassis to either side of the power cord is less than 460 kohms, the unit is defective.

LASER RADIATION

Do not stare into beam or view directly with optical instruments, class 3A laser product.

CONFIRMING THE SERVO

CAUTION:

The Optical Pick-up used for CD player may invite defection by an external noise, such as electrostatic, etc., please pay the following attention.

1. Use a conductive mat on a working table to avoid electrostatic damage.

2. A working personnel should use a wrist strap to ground human body.

3. Tools, etc., specially for a soldering iron must use with its tip grounded and without leakage of electricity. Utmost care must be taken to your clothes for electrostatic damaging in a low humidity environment.

CONFIRMING THE AUDIO

1. Necessary Equipment for Adjustment

Distortion--Factor Meter VTVM Low-Pass Filter (20kHz)

Reference Disc; DENON Audio Technical CD (38C39-7174)

2. Prior to Starting the Adjustment

1) Audio circuit shall be adjusted after adjustment of servo circuit.

3. Output Level Adjustment

1) Connect VTVM to the output connector of DN-C680. Use 1:1 600 ohm Audio Transformer between the unit and VTVMs in order for matching the unbalanced input of VTVM and the active bakanced output of DN-C680 as shown in figure.

2) Play track number "49".

3) While reading VTVM indication, adjust VR407 (L-ch) and VR408 (R-ch) so that the output level attains +18dBm (or desired level).

When LED is carrying out continuation lighting even of after initialization, please check whether the control signal line for FPGA initialization (pin 49, 64, 65, and 70) is carrying out the electrical connection, or it does not short-circuit with other signal lines, and correct fault. When LED is still carrying out continuation lighting, please correct in order of exchange of FLASH ROM (IC106), exchange of FPGA (IC112), and exchange of a microcomputer (IC137).

もし、LED が初期完了後も連続点灯している場合は FPGA 初期化のための制御信号線 (pin49,64,65,70) が導通しているか、他の信号線とショートしていないか確認し、修正して下さい。それでも LED が連続点灯している場合は、FLASHROM(IC106) の交換、FPGA(IC112) の交換、マイコン (IC137) の交換の順で修正を行って下さい。
