1. CONTRAST OF MISCELLANEOUS PARTS
NOTES: Parts marked by "NSP" are generally unavailable because they are not in our Master Spare Parts List.
A
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.
Screws adjacent to mark on product are used for disassembly.
For the applying amount of lubricants or glue, follow the instructions in this manual.
(In the case of no amount instructions, apply as you think it appropriate.)
Nos. indicate the pages and Nos. in the service manual for the base model.
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%).

2. DIAGNOSIS D
2.1 Pairing this unit and Bluetooth wireless technology device
Pairing with the unit (Initial registration)
In order for the unit to playback music stored on a Bluetooth capable device, pairing must first be performed.
Pairing should be performed when first using the unit with the Bluetooth capable device, or when the pairing data
on the device has been erased for any reason. Pairing is a step required to allow communication using Bluetooth
wireless technology to be carried out.
Pairing is performed the first time that you use the unit and the Bluetooth capable device together.
In order to allow communication using Bluetooth wireless technology to take place, pairing must be performed
on both the unit and the Bluetooth capable device.
After pressing the BT ADPT and switching to BT AUDIO input, perform the pairing procedure on the Bluetooth
capable device. If pairing has been performed correctly, you will not need to perform the pairing procedures for
the unit as shown below. E
Please refer to the user's manual for your Bluetooth capable device for more details.
1 Press STANDBY/ON and turn the power to the unit on.
2 Press BT ADPT.
The unit switches to BT AUDIO and WAITING DEVICE will be displayed on the front panel of the unit.
3 Turn on the power to the Bluetooth capable device that you wish to pair with, and
perform pairing procedure on it.
Pairing will start.
Place the Bluetooth capable device close to the unit.
Please refer to the user's manual for your Bluetooth capable device for details on when pairing can be per-
formed and the procedures required for pairing.
When PIN code entry is requested, enter 0000. (This unit does not accept any PIN code setting other than
0000.) F
4 Confirm on the Bluetooth capable device that pairing has been completed.
If pairing with the Bluetooth capable device has been completed correctly, CONNECTED will be displayed on the
front panel of the unit.
