MAIN board open/close detect switch (S809) tape
In performing the repair with the power supplied to the set, removing the MAIN board causes the set to be disabled. In such a case, fix a convex part of the open/close detect switch (S809 on MAIN board) with a tape in advance.

Replacement of CXD2661GA-2 (IC601) and CXR701080016GA (IC801) used in this set requires a special tool. Therefore, they cannot be replaced. On the set having the microcomputer version 1.000, the NV reset failure will occur. Therefore, in executing the NV reset during electrical adjustment, follow the troubleshooting method of NV reset to perform the NV reset (see page 17).

This set provides the Overall adjustment mode that allows CD and MO discs to be automatically adjusted when in the test mode. In this overall adjustment mode, the disc is discriminate between CD and MO, and each adjustment is automatically executed in order. If a fault is found, the system displays its location. Also, the manual mode allows each individual adjustment to be automatically adjusted. Operation in the test mode is performed with the remote commander. A key having no particular description in the text, indicates a remote commander key.
Operation in Setting the Test Mode
When the test mode becomes active, first the display check mode is selected. (Press the x key once, when the display check mode is not active) Other mode can be selected from the display check mode. When the test mode is set, the LCD repeats the following display.

Set LCD display

Setting Method of Test Mode
There are two different methods to set the test mode: 1 Short TAP801 (TEST) on the MAIN board with a solder bridge (connect pin y; of IC801 to the ground). Then, turn on the power.

When the X key is pressed and hold down, the display at that time is held so that display can be checked. Caution: On the set having the microcomputer version 1.000, the NV reset failure will occur. Therefore, in executing the NV reset during electrical adjustment, follow the troubleshooting method of NV reset to perform the NV reset (see page 17).

Releasing the Test Mode

For test mode set with the method 1: Turn off the power and open the solder bridge on TAP801 (TEST) on the MAIN board.
Note: Remove the solders completely. Remaining could be shorted with the chassis, etc.
For test mode set with the method 2: Turn off the power.

TAP801 (TEST)

Note: If electrical adjustment (see page 17) has not been finished completely, always start in the test mode. (The set cannot start in normal mode)

1 Playing an MD.

Before operating the player, make sure the HOLD function is off. For details, see To lock the controls. 1 Connect the headphones to the remote control. Make sure the plug is firmly inserted into the remote control. 2 Connect the headphones/earphones with the remote control to the i jack. 3 Press > N (or press the control towards N/> or. on the remote control). The player starts to play the first track and 1 is displayed on the player. When using the remote control, a short beep sounds in the headphones. 4 Press VOLUME +/ to adjust the volume. The volume indicator appears on the player and the remote control to allow you to check the volume. When you adjust the volume, a number from 0 to 10 is displayed to indicate the volume level on the player, and the volume level bar is indicated on the remote control.

Welcome!

Welcome to the world of the MiniDisc! Below are some of the features you will discover with the new MiniDisc player. Compact body with newly developed head-loading system. Insert or eject an MD with the slightest touch of a finger. Simple-to-use folding standup battery charger Insert the MD player into the folding standup battery charger for simple, onestep charging. By connecting an optional car battery cord to the battery charger, you can listen to the player in the car without worrying about battery rundown. LCD display built into player for easy viewing in the car An easy-to-see LCD display built into the player allows you to monitor track numbers when the remote control display is out of view.* Personalized sound through Digital Sound Preset functions You can store two sets of sound quality adjustments (made during playback) to two switches. Small body almost the size of a MiniDisc jacket Low power-consumption design for extended battery life. Easy-to-operate headphones/earphones remote control with backlit LCD Shock-resistant memory offsets up to 40 seconds of optical read errors.
* Do not operate the unit when you drive.

BPower Sources

When to recharge or replace the battery H
The battery should power consecutive playback for about 37 hours before you need to replace it. If you use both a dry battery and a rechargeable battery (consecutively), the total playback time should be about 64 hours. When the battery indication changes to r, the rechargeable battery or the dry battery is weak. Recharge the rechargeable battery or replace the dry battery. When the battery is exhausted, LOW BATT flashes in the display on the remote control and the power goes off. Note
The battery life may be shorter depending on operating conditions, the surrounding temperature, and the battery type.
(all repeat) All the tracks are played repeatedly.
TEL 03-3434-0261 http://www.baj.or.jp
(single repeat) A single track is played repeatedly.
