WARNING

CR-555/555DAB/N755

WARNING:

TO REDUCE THE RISK OF FIRE OR ELECTRIC SHOCK, DO NOT EXPOSE THIS APPLIANCE TO RAIN OR MOISTURE.

CAUTION:

TO REDUCE THE RISK OF ELECTRIC SHOCK, DO NOT REMOVE COVER (OR BACK). NO USER-SERVICEABLE PARTS INSIDE. REFER SERVICING TO QUALIFIED SERVICE PERSONNEL.

LASER CAUTION

This unit contains a semiconductor laser system and is classified as a “CLASS 1 LASER PRODUCT”. So, to use this model properly, read this Instruction Manual carefully. In case of any trouble, please contact the store where you purchased the unit. To prevent being exposed to the laser beam, do not try to open the enclosure.

CAUTION:

VISIBLE LASER RADIATION WHEN OPEN AND INTERLOCK FAILED OR DEFEATED. DO NOT STARE INTO BEAM.

CAUTION:

THIS PRODUCT UTILIZES A LASER. USE OF CONTROLS OR ADJUSTMENTS OR PERFORMANCE OF PROCEDURES OTHER THAN THOSE SPECIFIED HEREIN MAY RESULT IN HAZARDOUS RADIATION EXPOSURE.

WARNING

RISK OF ELECTRIC SHOCK

DO NOT OPEN

The lightn ing flash w ith arrowhead symbol, wi thin an equ ilateral triangle, is intended to aler t the user to the presence of uninsulated “dangerous voltage” within the product’s enclosure that may be of sufficient magnitude to constitute a risk of electric shock to persons.

The exclamation point within an equilateral triangle is intended to alert the user to the presence of important operating and maintenance (servicing) instructions in the literature accompanying the appliance.

The label on the right is applied on the rear panel except for USA and Canadian models.

1. This unit is a CLASS 1 LASER PRODUCT and employs a laser inside the cabinet.

2. To prevent the laser from being exposed, do not remove the cover. Refer servicing to qualified personnel.

LASER DIODE

Never look at the laser light beam through the objective lens. T he visible laser beam may harm the human eye. Use an appropriate viewer or TV camera to observe the laser beam.

Any laser diode will be damaged by a large current or pulse. Avoid current surges and electrostatic discharges. Safety grounding of the human body and all measuring equipment, jigs and tools is absolutely necessary. T he use of a grounding mat on the workbench and floor is necessary. Even a small electrostatic discharge from the human body may destroy the laser diode instantaneously or reduce its life time.

The pins of the laser diode may be shorted at the factory by a solder bridge at the FPC for protection during transportation and storage of the unit. If this is the case, open the short circuit (accessible from the bottom side of the module) quickly with grounded soldering iron (less than 300°C).

The damage of the diode might be indicated by an increase of the laser current.

STAND-BY. Remove power cord from power line.

TEST MODE

1) Main Microprocessor Version display

Press ON/STANDBY button while pressing down TONE button, when the unit is POWER ON.

2) DSP Version display.

Press INPUT button 1 times while Main Microproccesor version display.

3) Model display

Press INPUT button 1 times while DSP version display.

4)Display test

Press INPUT button 1 times while Model display.

5) Key test

Press INPUT button 1 times while FL full light.

TEST MODE for OPERATION

Push STANDBY/ON button while pushing down Return key after setting the Vol to minimum,

to display "TEST-1-00".

Push INPUT button ,then get the "TEST2-00"→"TEST3-00"→"TEST4-00" mode.

In the test mode, >>| / |<< of JOG DIAL is TEST MODE UP/DOWN.

INPUT button and JOG DIAL's originally operation can't work when it is in the test mode.

CR-555/555DAB/N755

OPERATION CHECK

1. CURRENT-DETECTION AND VOLTAGE-DETECTION CHECK

1)Change the state to "TEST-2-00".

2)The set never change to protect mode when 2 ohms load is connected to each channel under the conditions of peak-to-zero 17.5Vp

(35Vpp) output for both channels and no load by using the INTEGRA amplifier series designated circuit with 200Hz square wave.

3)The set must change to protect mode when 0.5 ohm load is connected to each channel under the conditions of peak-to-zero 17.5Vp

(35Vpp) output for L,R channels and no load by using the the INTEGRA ampifier series designated circuit with 200Hz square

wave.

4)When input +1.6V DC voltage more than 1sec to each channel trough 1KΩ resistor under no SP load, the set must change to protect

mode.

2. CONFIRMATION OF REMOTE CONTROL OPERATION

1)Confirm that the specified operations for each button are made.

2)Confirm RI opearion.

3. VOLH SIGNAL CHECK

1)Change the state to "TEST-4-36".

2)Input the -20dBFS signal of 1KHz to OPTICAL,If "Asb" indicator is displayed ,it's OK.NO Display is NG.

4. FRONT USB

Connect iPhone or iPod to Front USB terminal,Check the operation of playback by hearing.

5. Line2,Line3, Coaxial/Line out

Confirm the input and output of Line and the input of Line2/3 operation and Coaxial input operation by hearing test.

6. REAR USB

Connect USB memory to Rear USB terminal,Check the operation of playback by hearing.

7. ETHERNET TERMINAL

Connect LAN cable to Ethernet terminal,Please set to Test mode"3-11"Check the operation of playback by hearing.

Sampling frequency of 44.1KHz/48Khz are needed for Playback source.

8.USB DETECT CHECK

At first, Please set to Test mode"3-09",Connect USB memory to Front USB terminal.

Confirm the display of "DETECT OK”.

If the display is nothing, it's NG.
