Be careful not to apply force on the conductor when soldering or unsoldering. Notes on chip component replacement Never reuse a disconnected chip component. Notice that the minus side of a tantalum capacitor may be damaged by heat. CAUTION Use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous radiation exposure.

MZ-G750/R700 SECTION 1 SERVICING NOTE
NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK OR BASE UNIT The laser diode in the optical pick-up block may suffer electrostatic break-down because of the potential difference generated by the charged electrostatic load, etc. on clothing and the human body. During repair, pay attention to electrostatic break-down and also use the procedure in the printed matter which is included in the repair parts. The flexible board is easily damaged and should be handled with care. NOTES ON LASER DIODE EMISSION CHECK Never look into the laser diode emission from right above when checking it for adjustment. It is feared that you will lose your sight. NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK (LCX-4R) The laser diode in the optical pick-up block may suffer electrostatic break-down easily. When handling it, perform soldering bridge to the laser-tap on the flexible board. Also perform measures against electrostatic break-down sufficiently before the operation. The flexible board is easily damaged and should be handled with care. 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 (S806 on MAIN board) with a tape in advance. Handle the FLEXIBLE board (overwrite head) with care, as it has been soldered directly to the MAIN board. In repairing the component side of MAIN board, connect the FLEXIBLE board (overwrite head) and the MAIN board with the lead wires in advance. (See page 8)

Replacement of CDX2671-204GA (IC801) used in this set requires a special tool. On the set having the microcomputer version 1.000, some adjusted values were set in the manual mode at the shipment, but these data will be cleared when the NV is reset. Therefore, on the set having the microcomputer version 1.000, change the adjusted values following the Change of Adjusted Values immediately after the NV was reset. (See page 18) If the nonvolatile memory was replaced on the set, the modified program data must be written to the nonvolatile memory. In such a case, write the modified data that meets the microcomputer version following the patch data rewriting procedure at the replacement of nonvolatile memory. (See page 23)

MZ-G750/R700 SECTION 4 TEST MODE

4-1. Outline

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 set. A key having no particular description in the text, indicates a set key. For the LCD display, the LCD on the set is shown.
4-3. Operation in Setting the Test Mode
When the test mode becomes active, first the display check mode is selected. Other mode can be selected from the display check mode. When the test mode is set, the LCD repeats the following display.

Portable MiniDisc Player/Recorder
MiniDisc is a highly compact recordable digital audio format. The durable 2.5 discs are re-recordable almost indefinitely. The playback controls are essentially similar to those of a CD player; this document focuses on recording and editing.

The Sony MZ-R70 can record from an optical digital, analog, or microphone source. Optical uses a Mini-TOS plug, while the line and mic inputs use standard 1/8 plugs. If you are using a microphone with an XLR output, be sure to get an XLR to 1/8 adapter plug, available from Media Loan. To record optically, you must have a digital source with an optical output, such as a CD player. In optical recording, the level and track marks are set automatically.

Start Recording

1. Connect your source (mic, CD, etc.) 2. Press the OPEN Button (3). 3. Insert a disc (label side up) and close the cover. 4. Silde the RECORD switch (18) to the right. The unit will begin recording immediately. NOTE: To ensure that you begin recording at the end of the previous recording press the END SEARCH Button (2) before you record.
To adjust record settings, hold the PAUSE Button (9) and slide the RECORD Switch (18) to the right. More on record settings below.

Hold Function

The HOLD Switch (6), located on the bottom of the unit, is used to disable the buttons on the unit. When the HOLD Switch is activated none of the controls on the unit will respond. If you activate the HOLD Switch on the remote (34), none of the controls on the remote will respond. Neither switch affects the other device.
