Entering Service Menu> Connect the AC cable and power on MR16. After the bootup procedure is completed, the display on the right will appear on the MR16 LCD.
> Press the [MENU/ENTER] dial while holding down the [STOP] and [POWER] keys. If you do so, "Service Mode" is displayed on the MR16 LCD.
CAUTION: If the [POWER] key is held down for more than three seconds, MR16 turns off. Please be careful to expedite the above manipulation 2).
> Rotate the [MENU/ENTER] dial and select “Service Mode”. Then, press the [MENU/ENTER] dial. You can see that the following service menus will appear on the MR16 LCD.
> Select one of the service menus you would like to execute and press the [MENU/ENTER] dial.
Version
In the “Version” service menu, the current MR16 software version as well as the corresponding software programming date can be checked.
In the “Version” service menu, the current MR16 software version as well as the corresponding software programming date can be checked.
After selecting the “Version” menu, press
the [MENU/ENTER] dial to check the current software version and the programming
date.
By
pressing the STOP key, MR16 returns to the service menu select condition.
The
“Version Up” service menu allows you to update the MR16 software by placing the
software update file in the root directory tree of the MR16 3.5” internal hard
disk.
Advanced Format
MR16 checks the remaining capacity / partition information written on the internal HD in the bootup process after powering on. In case this information does not match the current HD condition, the “Advanced Format” service menu can be used. For example, even if no song has been created (recorded) but the remaining capacity indicates only 10MB, execute the “Advanced Format” menu.
Remember that executing the “Advanced Format” deletes all the songs recorded on the internal HD.
Upon completion of “Advanced Format”, the message “Boot Sector Clear” appears on the LCD
[In case MR16 is not booted up correctly and displays an alert message such as “Please Wait!” permanently, power if off once. Then, while holding down the [STOP] key, power on MR16. This mode allows to boot up without loading any recorded songs. Next, execute the “Advanced Format” menu.]

6)
After checking, press the [MENU/ENTER] dial to proceed the next Display Test.
The next test is to check if the tact switches on the MR16 top panel except the
POWER SW is in good contact. If the tact switch is pressed, the corresponding
asterisk mark on the MR16 LCD will go out. If not, the tact switch might be
worn out and be replaced.
After all the tact switches are confirmed to be in good contact, the display on the right will appear on the MR16 LCD.

Bus
Check
This menu checks if various bus signals connected to the CPU are correctly working or not.
1) After selecting the “Bus Check” menu, connect the foot SW to the foot SW jack and the USB cable between the USB and USB HOST ports.
2) Press the [MENU/ENTER] dial to initiate the Bus Check mode.

AUDIO BUS
The AUDIO BUS setting is fixed at “THRU” in this menu. In the “THRU” setting, the A/D and D/A converters are internally connected. Also the CHAN A/C and B/D PAN setting are set to left and right respectively. Thus, the signals fed to CHAN A and C are summed and output from the STEREO OUT L and the signal fed to CHAN B and D are summed and output from the STEREO OUT R.
This mode is convenient when checking the input circuit.
