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.

WARNING

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.

(FOR USA MODEL ONLY)

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

D

E

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.

Reading should not be above

0.5 mA

Earth ground

Device under test

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

Test all exposed metal surfaces

Leakage current tester

AC Leakage Test

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 parts list in this Service Manual. 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.

A

NOTES:

Parts marked by "NSP" are generally unavailable because they are not in our Master Spare Parts List. The mark found on some component parts indicates the importance of the safety factor of the part. Therefore, when replacing, be sure to use parts of identical designation. When ordering resistors, first convert resistance values into code form as shown in the following examples. Ex.1 When there are 2 effective digits (any digit apart from 0), such as 560 ohm and 47k ohm (tolerance is shown by J=5%, and K=10%).

560 Ω 47k Ω

0.5 Ω 1 Ω

56 x 10 47 x 10 R50 1R0

Ex.2 When there are 3 effective digits (such as in high precision metal film resistors).

5.62k Ω

7.1.2 NOTES ON REPLACE OF PARTS

(ID-related)

The ID number for an individual product is stored in the EEPROMs (U7 for the TX module, U11 for the RX module) of each

A

module (TX module: AXF7006, RX module: AXF7008). It should be noted that wireless communications cannot be performed unless these ID numbers are identical.

1. Replacement of the TX or RX module

Upon replacement of the TX (AXF7006) or RX (AXF7008) module, remove the EEPROM from the original module and mount it on the new one.

2. Replacement of the EEPROMs (U7 and U11)

Using service part AXX7169 (a kit containing two EEPROMs with identical ID numbers stored in them,) replace both EEPROMs when either needs to be replaced.

Note : The AXX7169 is a service part containing two EEPROMs, both of which must be replaced when either needs to be

B

replaced.

7.1.3 DIAGNOSIS OF THE AMPLIFIER SECTION

You can diagnose the amplifier section even if the transmitter section is not available. Input audio signals to the Jumper Wire for service use indicated below. At that time remove the RX MODULE.

PROTECT Operation Description

This circuit has following five items that performs the Short detection.

1 PRE5 2 PRE12 3 FAN +B (for Hi rotation) 4 FAN short 5 FAN open

About 1 to 3 When the voltages of 1 to 3 fell in the voltage (less than

about 3.2V) that Q71 turned ON, and turn Q3654 ON via R73 and D75. → XPROTECT becomes low.

About FAN short or open detection At normal state:

The voltage appears in Q3655 base by current that flows to the FAN, and so Q3655 is always ON. Q3654 cannot turn ON so that the voltage appears only with Vce(sat) of Q3655 in D3665 anode. In addition, Q3654 cannot turn ON so that the voltage (Vb × 1/4.3=lesst than 0.8V) that divided the base voltage of Q3655 with 33k and 10k is the voltage of D3664 anode. Therefore, Q3654 maintains the OFF state.

In the short or open state: The voltage appears at D3664 anode in the short state and appears at D3665 anode in the open state. Q3654 turns ON and XPROTECT becomes low (Active).

[ When L+ position becomes 0V ] As the Amplifier Power IC is single power supply, the bias voltage for SP terminal is always about 8V. Therefore the voltage of point A is 5.1V, point B is 6.9V, and then Q3451 becomes ON. Then the voltage of DC PROTECT becomes 7V.

The default setting is AUTO . If you experience poor reception due to your listening environment, you can improve the reception of the receiver by switching to MANUAL and selecting an appropriate frequency using the CHANNEL

button on the transmitter. Press and hold for

more than 5 seconds to switch between

AUTO and MANUAL.

• Make sure to stop/turn off the source and switch off the wireless speaker when switching speaker systems. The wireless

Press to select a frequency channel. The frequency channel changes sequentially

each time the button is pressed: speaker will output the source at very loud volumes if the wireless speaker is set to

SURROUND and the main unit is set to W.Stereo. In this case, the volume

control has no effect, so please follow these precautions.

11 Antenna

• The VOLUME knob has no effect when WIRELESS MODE is set to SURROUND.

• When you select AUTO , the channel will automatically be set to the same one

selected on the transmitter.

• Even when not in use, the fan in the

wireless speaker will continue to operate. Switching off the wireless speaker when not in use will increase product life.
