HOW TO INSERT THE TWO SIMM (OMS-770) TO EXPAND MEMORY/
CAUTION!
1. Two SIMM (OMS-770) of 1M byte each must be
installed. If just one single unit is installed, the DJ-70
Will not recognize it.
2. The OMS-770 is the official memory expansion for the
DJ-70. If memory modules other than the OMS-770 are
used, Roland cannot be responsible for faulty
operation or for service of any resulting malfunctions.

Remove the screws (5pcs) as indicated by "B"
arrows to take out the keyboard. (Refer to Fig. 2)
Install the two SIMM (OMS-770) into the sockets as
shown in Fig. 3and press them until you hear aclick.
Verify the expanded memory capacity by
following the procedure shown below.
Turn on DJ-70 and the LCD will read the amount
of currently operative memory immediately after
the initial screen. In this case, the value should be
4Mbytes.

This allows you to adjust the MSB of the D/A
converter.
Before entering this test, connect astereo phones to
the PHONES jack.
When you press "A" acontinous tone will be output
from the PHONES fack.
Adjust the trimmer potentiometer, VR1, on the analog
board to reduce the continous tone to the lowest
possible volume.
When you press "B" the continous tone will be
stopped.
When you have completed press "EXIT" to exit
and to return to ANALOG BOARD TEST MENU.

This test checks the operations of the D/A converter.
Before you enter this test, connect amonitor speaker
and an oscilloscope (set to 1V/div.,0.2mS/div.) to the
rear panel STEREO OUT L(mono) jack, and set the
front panel VOLUME knob to maximum (MAX).
Use the panel switches, "SI "for decrement and "S2"
for increment, to adjust the displayed level over the
range 1-13, and the level of the continous tone, being
output from OUT will change accordingly.
The level will double for each increment and ,at the
maximum (13), it will be Min.4.5Vpp; Max.5.5Vpp.
Connect the oscilloscope to the PHONES jack, set the
PHONES volume to MAX and decrment the displayed
level to 12 using "SI" button.
The level of the continous tone will be Min.13.5Vpp.
