Notice that the minus side of a tantalum capacitor may be damaged by heat. z UNLEADED SOLDER Boards requiring use of unleaded solder are printed with the lead free mark (LF) indicating the solder contains no lead. (Caution: Some printed circuit boards may not come printed with the lead free mark due to their particular size) : LEAD FREE MARK Unleaded solder has the following characteristics. Unleaded solder melts at a temperature about 40 C higher than ordinary solder. Ordinary soldering irons can be used but the iron tip has to be applied to the solder joint for a slightly longer time. Soldering irons using a temperature regulator should be set to about 350 C. Caution: The printed pattern (copper foil) may peel away if the heated tip is applied for too long, so be careful! Strong viscosity Unleaded solder is more viscou-s (sticky, less prone to flow) than ordinary solder so use caution not to let solder bridges occur such as on IC pins, etc. Usable with ordinary solder It is best to use only unleaded solder but unleaded solder may also be added to ordinary solder.

If they are not completed, the unit will not operate normally. * BAD BLOCK check is to check the flash ROM memory area (the BAD BLOCK area) where data cannot be guaranteed. The resultant information of this check is stored in the TOC- AREA so that the BAD BLOCK area should not be used. BAD BLOCK Check Procedure 1.When the power is turned on after the flash memory (IC701) is replaced, the BAD BLOCK check starts automatically and the OPR (D701) lights in orange. 2.In about 30 seconds after start of the check, the OPR (D701) changes the color to green indicating that the check is completed. 1-2.NOTES FOR REPLACEMENT OF THE MICROCOMPUTER (IC702) The IC702 on the MAIN board has former and new types of models. Former type : MB91F233LLGA-GE1 (flash microcomputer) New type: MB91233LLGA-G-107E1 (mask microcomputer) The service parts include only new types of models. When replacing the IC702, check the model number. The transistors Q706 and Q707 for program write should be removed when the previous type is installed.

Layers The service mode has a maximum of three layers according to the mode items: Layer for item selection Layer for operation selection Layer for operating state or test result display To switch to another layer in a certain layer, basically Bx key switches to another layer and x STOP key returns to the previous layer. To select the next item/operation in a layer, the key is used. To select the previous item/operation, the . key is used. When the items are circulated by selecting them, the first item is displayed.

RTC connection and operation This mode provides self-check of the RTC connection and operation. It includes three checks: RTC connection check, data write and read check, and XRTCINTR (interrupt signal) check. There is no layer (display) for operation selection. Result of this check is shown as “OK” or “BAD”. RTCRTC OK RTC BAD Bx x Item selection displayResult display Result display Check OK Check NG STOP 7. A/D KEY voltage This mode displays the CPU input voltages of KEYIN0 and KEYIN1 in hexadecimal (HEX) format. Pressing of a specific key causes the corresponding voltage to be displayed. In this mode, the x STOP key will display the corresponding voltage while it is being pressed. The display will be returned to the layer for item selection by releasing the x STOP key. There is no layer (display) for operation selection. KEY KEY A8 FF Bx x Item selection displayResult display Voltage of KEYIN0 Voltage of KEYIN1 STOP 8. BATTERY/DC-IN CPU input detection voltage This mode displays the CPU input voltage of either BATTERY or DC-IN in hexadecimal (HEX) format. A battery full mark is shown during BATTERY operation and this mark is extinguished during DC-IN operation. There is no layer (display) for operation selection.

The red and green LEDs are controlled at the same time. 10. USB test This mode provides VBUS ON/OFF display and SUSPEND test. There is no layer (display) for operation selection. The Bx key displays the VBUS status as “ON” or “OFF”. With VBUS ON, turning the HOLD switch ON causes SUSPEND mode to be performed. VBUS TEST Bx LEDLED ON x Item selection display LED: OFFON Result display STOP SUSPEND TEST With VBUS ON, turning the HOLD switch ON causes SUSPEND mode to be performed. To cancel this mode, switch VBUS to OFF.

KEY proof-test In this mode, counts are displayed by pressing a specific key. It is possible to check how many times the key is pressed for KEY proof-test. Keys to be tested include slide switches (HOLD and MIC SENS). Counts are displayed to the upper limit of “999999” in decimal format. However, the value will not be reset in this mode. To exit from this mode, the power should be turned off. KEY COUNT KEYKEY - - - -000000 BxBx Item selection display The counter is incremented each time a key is pressed. 12. MENU and FLASH MEMORY contents resetting This mode initializes MENU information (including clock to be set) and all erases all the folders. In order to complete this test, all the keys and all the slide switches must bee operated. In control of keys and slide switches, their names a displayed. The WAKE UP signal is also checked for tact keys. If any key or switch names are not displayed, the controls are faulty. To exit from this mode, the power should be turned off.
