The matters described may differ according to the model. Important Notes When Replacing the Circuit Board The M-40

11、0 saves a variety of data in the flash ROM, SRAM, and RTC on the Main Board. Before replacement, be sure to refer to “Saving Data” (p. 27) and “Loading Data” (p. 28) in this Service Notes to save the data, then load it back into the unit after replacing the circuit board. The unit is also provided w

12、ith an internal-clock feature, so remember also to set the date and time according to the procedures in “Setting the Internal Clock” (p. 30). How the MAC Address Is Saved The M-400s REAC uses Ethernet technology, so each unit must be assigned a unique MAC address. The MAC address is saved in a seria

13、l EEPROM on the Main Board, and an appropriate MAC address is assigned when the unit is shipped from the factory. When the Main Board is replaced in servicing, a suitable MAC address matched to the product type and serial number must be saved on the Main Board. For details on the task flow for gener

14、ating a MAC address and how to save it on the unit, refer to “Setting the MAC Address” (p. 29) in this Service Notes document. Important Notes When Replacing the Lithium Battery The M-400 uses SRAM to perform read/write access for some of the parameters required for operation. Removing the lithium b

15、attery causes the data in the SRAM to be lost. The internal clock is also powered by the lithium battery. Before replacing the lithium battery, be sure to refer to “Saving Data” (p. 27) and “Loading Data” (p. 28) in this Service Notes to save the data and then load it back into the unit after replac

16、ement. Also, after replacement, set the internal clock according to the procedure described in “Setting the Internal Clock” (p. 30). Startup Modes The M-400 has the two startup modes described below. Factory Test Mode This mode is for checking the version, conducting various tests, saving the MAC ad

17、dress, and the like. Startup method: Hold down the F6 and F8 function buttons and the METER button and switch on the power. Normal Mode This is the mode for performing normal operation. Startup method: Switch on the power without holding down any other buttons. Back Up User Data! User data may be lo

18、st during the course of the procedure. Refer to “Users Data Save and Load” in the Service Notes and save the data. After completing the procedure, restore the backed-up data to the product. USB Memory Devices For the USB memory device used to update the M-400 and for saving and loading data, be sure

19、 to use a device that has been formatted on the M-400. For information on how to perform formatting, refer to the section entitled “Formatting a USB Memory Device” (p. 27). Part Replacement When replacing components near the power-supply circuit or a heat- generating circuit (such as a circuit provi

20、ded with a heat sink or including a cement resistor), carry out the procedure according to the instructions with respect to the part number, direction, and attachment position (mounting so as to leave an air gap between the component and the circuit board, etc.). Parts List A component whose part co

21、de is * cannot be supplied as a service part because one of the following reasons applies. Because it is supplied as an assembled part (under a different part code). Because a number of circuit boards are grouped together and supplied as a single circuit board (under a different part code). Because

22、supply is prohibited due to copyright restrictions. Because reissuance is restricted. Because the part is made to order (at current market price). Circuit Diagram In the circuit diagram, “NIU” is an abbreviation for “Not in Use,” and “UnPop” is an abbreviation for “Unpopulated.” They both mean non-m

23、ounted components. The circuit board and circuit board diagram show silk-screened indications, but no components are mounted.
