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.

In case of using 4K/60p-compatible TV and no picure.

The receiver’s HDMI input terminals support the 4K/60p signal. However, there are two types of terminals as follows.

 Type 1: 4K/60p 4:4:4 24 bit signal (transmission speed up to 18 Gbps) can be transmitted: BD, DVD (HDMI IN 1), SAT (HDMI IN 2)  Type 2: 4K/60p 4:2:0 24 bit signal can be transmitted (4K/60p 4:4:4 24 bit signal is not supported, transmission speed up to 10.2 Gbps):

HDMI input terminals other than the above

NOTE: All input terminals are type 2 when HDZONE is turned on.

1. When a source device that does not support the 4K/60p 4:4:4 24 bit signal is connected to a type 1 terminal, the video image may become reddish, sound may not be output, or 3D signals may not be output for some devices. For such devices, try the following.

*This is not a malfunction of the receiver.

 Connect the device to a type 2 terminal instead of the type 1 terminal.  It is also possible to set all input terminals to type 2. Set the following “HDMI 4K/60p signal output setting” to “4:2:0”.

2. When the video image is not output, is interrupted, or there is noise, the cause may be the HDMI cable. (Some HDMI cables do not support 4K/60p 4:4:4 24 bit signal transmission.) In such cases, set the following “HDMI 4K/60p signal output setting” to “4:2:0”.

HDMI 4K/60p signal output setting

Operation is performed on the front panel of the unit. You cannot perform the setting if the multizone function is not set to MULTI ZONE OFF.

1 Switch the receiver into standby.

2 While holding down ENTER on the front panel, press  STANDBY/ON.

The display shows RESET  NO .

3 Use / to select ‘4K/60p’.

4 Use / to select the signal to set.

 4:4:4 – Select this setting when connecting to a 4K/60p 4:4:4 24 bit compatible TV using HDMI. More high quality video images can be enjoyed.  4:2:0 – Select this setting when connecting to a 4K/60p 4:2:0 24 bit compatible TV using HDMI.

5 When you’re finished, press RETURN.

Precautions

Files are stored in Root of USB memory. Files are read from Root of USB memory.

 To make operations such as moving files, be sure to assign the saved file in Root

of the USB memory. Also please be careful not to assign *.avr in multiple numbers.

The time and date of updating for saved file is fixed to "2006/03/08 20:01." In principle, please implement Load without making of factory default settings.

[Cautions]

You cannot use the backup function with USB memory until the Network Module software starts. It takes about 60 seconds before the Network Module software starts.

Depending on the type of USB memory device, the setting file may not have properly been saved even though

[COMPLETE] is displayed after a SAVE process. Before replacing the DIGITAL MAIN_L ASSY, perform a LOAD process and check that [COMPLETE] is displayed.
