■ TO SERVICE PERSONNEL

1. Critical Components Information. Components having special characteristics are marked Z and must be replaced with parts having specifications equal to those originally installed.

2. Leakage Current Measurement (For 120V Models Only). When service has been completed, it is imperative to verify that all exposed conductive surfaces are properly insulated from supply circuits.

● Meter impedance should be equivalent to 1500 ohm shunted

by 0.15µF.

“CAUTION”

“F201 : FOR CONTINUED PROTECTION AGAINST RISK OF FIRE, REPLACE ONLY WITH SAME TYPE 2.0A, 125V FUSE.” “F202 : FOR CONTINUED PROTECTION AGAINST RISK OF FIRE, REPLACE ONLY WITH SAME TYPE 4.0A, 125V FUSE.”

CAUTION

F201 : REPLACE WITH SAME TYPE 2.0A, 125V FUSE. F202 : REPLACE WITH SAME TYPE 4.0A, 125V FUSE.

ATTENTION

GX-505/VCD

F201 : UTILISER UN FUSIBLE DE RECHANGE DE MEME TYPE DE 2.0A, 125V. F202 : UTILISER UN FUSIBLE DE RECHANGE DE MEME TYPE DE 4.0A, 125V.

WARNING: CHEMICAL CONTENT NOTICE!

● Leakage current must not exceed 0.5mA.

● Be sure to test for leakage with the AC plug in both

polarities.

EQUIVALENT

The solder used in the production of this product contains LEAD. In addition, other electrical/electronic and/or plastic (where applicable) components may also contain traces of chemicals found by the California Health and Welfare Agency (and possibly other entities) to cause cancer and/or birth defects or other reproductive harm.

DO NOT PLACE SOLDER, ELECTRICAL/ELECTRONIC OR PLASTIC COMPONENTS IN YOUR MOUTH FOR ANY REASON WHATSOEVER!

Avoid prolonged, unprotected contact between solder and your skin! When soldering, do not inhale solder fumes or expose eyes to solder/flux vapor!

If you come in contact with solder or components located inside the enclosure of this product, wash your hands before handling food.

WARNING: Laser Safety

This product contains a laser beam component. This component may emit invisible, as well as visible radiation, which may cause eye damage. To protect your eyes and skin from laser radiation, the following precautions must be used during servicing of the unit.

1) When testing and/or repairing any component within the product, keep your eyes and skin more than 30 cm away from the laser pick-up unit at all times. Do not stare at the laser beam at any time.

2) Do not attempt readjustment, disassembly or repair of the laser pick-up, unless noted elsewhere in this manual.

3) CAUTION : Use of controls, adjustments or performance of procedures other than those specified herein may result in hazardous radiation exposure.

GX-505/GX-505VCD

Laser Emitting conditions:

1) When the Top Cover is removed, and the STANDBY SW is turned to the "ON" position, the laser component will emit a beam for several seconds to detect if a disc is present. During this time (5-10 sec.) the laser may radiate through the lens of the laser pick-up unit. Do not attempt any servicing during this period! If no disc is detected, the laser will stop emitting the beam. When a disc is set, you will not be exposed to any laser emissions.

2) The laser power level can be adjusted with the VR on the pick-up PWB, however, this level has been set by the factory prior to shipping from the factory. Do not adjust this laser level control unless instruction is provided elsewhere in this manual. Adjustment of this control can increase the laser emission level from the device.

■ TEST MODE

To facilitate inspection, measurement and location of any faulty point, 6 types of built-in Test Modes are provided, one for each section.

• System Test Mode : Test mode for the system section. It is also used when entering the test mode for each section.

• Receiver Test Mode : Test mode for the receiver section

• Tape Test Mode : Test mode for the deck section

• CD Test Mode : Test mode for the CD section

• MD Test Mode : Test mode for the MD section (unused for this unit)

• All Function Test Mode : Test mode for all functions

■ SYSTEM TEST MODE

This test mode is used for the system section. Also, this mode must be executed first when entering the test mode for each section.

Starting Procedure

In the STANDBY mode, press the STANDBY/ON button while pressing the RANDOM button and the PLAY/ PAUSE(CD) button simultaneously. Once the SYSTEM TEST MODE is set, causal factors for the previous power off appear on the FL display.

■ RECEIVER TEST MODE

When the RECEIVER TEST MODE is set through the SYSTEM TEST MODE, “01 G.E.TEST” appears on the FL display. (01 is the test program No.)

Test programs from 01 to 25 are incorporated in RECEIVER TEST MODE.

Operation Procedure (Selection/execution of Test Program)

1) Select the test program by pressing the rTAPE (up) or eTAPE (down) button.

2) Pressing the STANDBY/ON button will execute the selected test program.

3) Repeat selection/execution of the test program as necessary.

CAUTION : When executing Test program No. 2 RAM CLEAR, be sure to write down the preset memory contents of the

tuner, using a table like the one shown below. Execution of RAM CLEAR will set the memory contents of the tuner back to the factory preset state which means that all the memories preset by the user will be erased.

■ TAPE TEST MODE

When the TAPE TEST MODE is set through the SYSTEM TEST MODE, “Tape Test XXXX” appears on the FL display. (XXXX is the counter value.) The operating condition of the deck section will be as follows.

• When the reverse mode is set to “endless”, the number of playback repetition becomes unlimited. (It is set to “8” times in the normal operating mode.)

• When in the REC mode, AUX/MD is used automatically for the input source.

If the blue background does not appear, the possibility is that the VCD module has failed. NOTE: None of the components of the VCD module can be supplied separately. Only a VCD module unit (VZ150200) is available.

■ ALL FUNCTION TEST MODE

When ALL FUNCTION TEST MODE is set through SYSTEM TEST MODE, “AUX/MD” appears on the FL display.

The operation condition in this mode will be as follows.

• AUX/MD is used as the input source of the receiver section, which is then set to the Dolby Pro Logic mode (GX505VCD only).

• When a CD is loaded, Full Repeat Play is executed automatically for it.

• When a cassette tape is loaded, Endless Rec Play is executed by the cassette deck automatically.

■ CD ERROR MESSAGES

Teh error message can be obtained on the display by pushing the STOP and TIME buttons simultaneously when the CD has stopped (sometimes with the tray open) by an error.

When "MECHA ER" message appears on the display; Possible symptoms are, the clamp does not move up or down, the table does not turn, mecha. sensor switch malfunctions, etc. The normal operation may be restored by tuning off the power once and then on again. If it does not work in this way, disassemble the CD mechanical unit and investigate the cause of the failure.

■ ADJUSTMENTS (DECK SECTION ONLY)

1. Before adjustment

● Since head magnetization, dust accumulations, etc.

are likely to introduce error in the various characteristics, it is very important that the heads are properly demagnetized and cleaned.

● Make adjustments of mechanical system, playback

system and recording system in that order.

● Except for azimuth adjustment, adjust in the forward

direction.

●

Adjust using the TAPE TEST MODE (shown on page 16).

2. Instruments required

● Audio frequency oscillator

● ACVM or dual channel (ACVM)

● DCVM

● Wow/flutter meter
