1. SAFETY PRECAUTIONS

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

LEAKAGE CURRENT CHECK

Measure leakage current to a known earth ground (water pipe, conduit, etc.) by connecting a leakage current tester such as Simpson Model 229-2 or equivalent between the earth ground and all exposed metal parts of the appliance (input/output terminals, screwheads, metal overlays, control shaft, etc.). Plug the AC line cord of the appliance directly into a 120V AC 60 Hz outlet and turn the AC power switch on. Any current measured must not exceed 0.5 mA.

ANY MEASUREMENTS NOT WITHIN THE LIMITS OUTLINED ABOVE ARE INDICATIVE OF A POTENTIAL SHOCK HAZARD AND MUST BE CORRECTED BEFORE RETURNING THE APPLIANCE TO THE CUSTOMER.

2. PRODUCT SAFETY NOTICE

Many electrical and mechanical parts in the appliance have special safety related characteristics. These are often not evident from visual inspection nor the protection afforded by them necessarily can be obtained by using replacement components rated for voltage, wattage, etc. Replacement parts which have these special safety characteristics are identified in this Service Manual. Electrical components having such features are identified by marking with a > on the schematics and on the parts list in this Ser

vice Manua

l. The use of a substitute replacement component which does not have the same safety characteristics as the PIONEER recommended replacement one, shown in the parts list in this Service Manual, may create shock, fire, or other hazards. Product Safety is continuously under review and new instructions are issued from time to time. For the latest information, always consult the current PIONEER Service Manual. A subscription to, or additional copies of, PIONEER Service Manual may be obtained at a nominal charge from PIONEER.

Leakage current tester

Reading should not be above

0.5 mA

Device under test

Test all exposed metal surfaces

Also test with plug reversed (Using AC adapter plug as required)

NOTICE (FOR CANADIAN MODEL ONLY) Fuse symbols (fast operating fuse) and/or (slow operating fuse) on PCB indicate that replacement parts must be of identical designation.

REMARQUE (POUR MODÈLE CANADIEN SEULEMENT) Les symboles de fusible (fusible de type rapide) et/ou (fusible de type lent) sur CCI indiquent que les pièces de remplacement doivent avoir la même désignation.

This service manual is intended for qualified service technicians ; it is not meant for the casual do-it- yourselfer. Qualified technicians have the necessary test equipment and tools, and have been trained to properly and safely repair complex products such as those covered by this manual. Improperly performed repairs can adversely affect the safety and reliability of the product and may void the warranty. If you are not qualified to perform the repair of this product properly and safely, you should not risk trying to do so and refer the repair to a qualified service technician.

• For environmental protection, lead-free solder is used on the printed circuit boards mounted in this unit. Be sure to use lead-free solder and a soldering iron that can meet specifications for use with lead-free solders for repairs accompanied by reworking of soldering.

• Compared with conventional eutectic solders, lead-free solders have higher melting points, by approximately 40 ºC. Therefore, for lead-free soldering, the tip temperature of a soldering iron must be set to around 373 ºC in general, although the temperature depends on the heat capacity of the PC board on which reworking is required and the weight of the tip of the soldering iron.

Do NOT use a soldering iron whose tip temperature cannot be controlled. Compared with eutectic solders, lead-free solders have higher bond strengths but slower wetting times and higher melting

temperatures (hard to melt/easy to harden). The following lead-free solders are available as service parts:

• Parts numbers of lead-free solder: GYP1006 1.0 in dia. GYP1007 0.6 in dia. GYP1008 0.3 in dia.

This unit supports the following file formats.

•

Note that some file formats are not available for

playback although they are listed as playable file formats.

•

If an attempt is made to play files with unsupported

formats, the sound may be intermittent or be accompanied by noise. In such cases, confirm that the file format is compatible with this unit.

•

The compatibility of file formats varies depending

on the type of server. Check with your server to ensure the compatibility of file formats supported by your server.

•

Depending on the server, some file types not

supported by this unit may be converted and output. For details, consult the server’s operating instructions.

•

Internet radio playback may be affected by the

Internet communications environment, and in this case playback may not be possible even with the file formats listed here

About playback behavior over a network

• Playback may stall when the PC is switched off or any media files stored on it are deleted while

playing content.

• If there are problems within the network environment (heavy network traffic, etc.) content may not be displayed or played properly (playback may be interrupted or stalled). For best performance, a 100BASE-TX connection between player and PC is recommended.

• If several clients are playing simultaneously, as the case may be, playback is interrupted or stalled.

• Depending on the security software installed on a connected PC and the setting of such software, network connection may be blocked.

Confirm replay of a music file for test with the same format as corresponding file format at the front USB terminal. (Confirm music files with all file formats should be replayed.)

No abnormalities should exist in actions such as audio, screen display, etc.

Check the external package

No scratches or dirt on its appearance after receiving it for service.

To keep the product quality after servicing, confirm recommended check points shown below.

See the table below for the items to be checked regarding audio.

A music file for test with corresponding file format should be used after downloading from the service dedicated Web Site onto an USB memory, etc.

In the event of UART communication

error with the BT module, BT error 5

is displayed.

Since POW_USB_W remains in High

the detection continues even after the

When the detection is confirmed

during the high-speed startup

Standby, transit POW_USB_W to

Low. After that, when the power is

turned ON, POW_USB_W is set to

High and after a lapse of 10 ms, the

detection starts again.

This protection operation is intended

for protection of the external

N-50

1. Service Mode

When the device is put in the Service Mode, the dedicated menu starts up. As long as the menu is open, the Service Mode is in operation. The items implemented by the menu are as follows:

· Check of Versions for MainCPU / SubCPU / DSP

· Check of Model Information (For which is SubCPU in operation, N-30(N-30-K/-S) or N-50(N-50-K/-S)?)

· Check of Network Information

· Update of USB for MainCPU / SubCPU

· Check of the number of protection circuit detections and clear

· Factory Setting

In the Service Mode, the protection circuit detection operates in the same way as during in the normal operation.

2. How to enter the Service Mode

Enter "ESC(A85F)"  "+10(A81F)" on the service remote controller GGF1381 while the power of the Main Unit is ON, and the menu for the Service Mode starts up.

∗ If any input from another remote controller is made between "ESC" and "+10", the Service Mode is not entered.

The entry status of the "ESC" key is cleared at the time of Power OFF.

3. How to leave the Service Mode

When the menu is left, the Service Mode exits. The menu is left by switching of functions, Power OFF or the return key input on the top-end layer of the menu.

4. Menu

The operation of the menu shall be conducted with the cursor keys of the product’s remote controller. Use the Enter key for selection of an item and use the Return key for return of one layer. The top menu is as shown in the screen below.

In addition, menu operation by the Main Unit button is also capable if attached remote controller is not available. In that case, perform the following actions;

In some menu, it is unable to return to one hierarchy layer before with the [] button. In that case, please exit from the Service Mode once with function button, etc.
