Test Mode - Roland D2 Service Notes

Jun. 2001
If the 7-segement LED displays "SYS—" and the check sum ("FF 7d", for
instanceÅjalternately, updating has not ended successfully.
Repeat the updating procedure from the first step.
Actions to be taken when normal
startup of the D2 is disabled
Overview
The D2 is equipped with a flash memory for saving user data.
If you inadvertently turn the D2's power off while writing data to the flash
memory, normal startup will be disabled (the display freezes on the start
screen) depending on the seriousness of the damage done to the flash memory.
Since the problem cannot be fixed by simply executing updating, initialize
the flash memory first and then execute updating to restore the normal state.
Note, however, that the restoring operation detetes all user data.
1.
Turn the D2's power on while holding down the [ENTER], [RPS] and
[ASSIGN1] buttons at the same time.
The 7-segment LED will display "——".
2.
Press the [1] and [7] buttons of [PART SELECT/MUTE] in this order.
"UsrInt" will be displayed on the 7-segment LED, and the [R] to [7] LEDs of
[PART SELECT/MUTE] will light up sequentially.
3.
When the 7-segment LED display becomes "000000" and all [PART
ELECT/MUTE] LEDs are lit, initialization of the flash memory is
complete.
It takes about 10 seconds.
4.
Turn the D2's power off and on again to start automatic factory reset.
After factory reset, the D2 will automatically start up from the same screen as
when power is turned on.

Proceed with updating after initializing the flash memory according to
