About Memory
information concerning the number of blocks, or noise and distortion.
• If the jumper is not moved from the “STD” position to the “EXP” position, no memory in the
expansion slots will be recognized. The wrong number of blocks will be displayed on the
Edit/System•MIDI page.
• If the jumper is moved from the “STD” to the “EXP” position and there are no SIMMs in the
expansion slots, the system will not boot up (display will be blank).
• 1m x 9 or 4m x 9 parity SIMMs (for IBM PC compatibles) should not be used. Only 1m x 8 or
4m x 8 (Macintosh) SIMMs should be used.
Troubleshooting Memory Expansion
If the correct number of blocks is not displayed on the Edit/System•MIDI page:
1. Make sure that there is no mix-up between 4m x 8 and 1m x 8 SIMMs (or that the store did not
sell you the wrong parts).
2. Check that the jumper is in the correct position.
3. Check that you are using one of the five proper configurations. Improper configurations may
work, but they will not work properly.
Make sure that you are careful when removing the SIMMs. If the plastic retaining posts are
broken, the SIMMs will not stay in place, and the main board will have to be replaced at an
Authorized ENSONIQ Repair Station (a costly error).
An Important Note About ElectroStatic Discharge
SIMMs are susceptible to ElectroStatic Discharge (ESD) commonly known as “static.”
ElectroStatic Discharge can destroy or damage SIMMs. In order to minimize the possibility of
causing ESD damage, here are some procedures you can follow when installing SIMMs:
1. Before installing SIMMs, you should be grounded by using a ground strap to discharge any
static electric charge built up on your body. The ground strap attaches to your wrist and a
ground source allowing your hands to be free to work.
2. Avoid any unnecessary movement, such as scuffing your feet when handling SIMMs, since
most movement can generate additional charges of static electricity.
3. Minimize the handling of the SIMMs. Keep them in their static free packages until needed.
Only transport or store the SIMMs in their protective packages.
4. When handling the SIMMs, avoid touching the connector pins. Try to handle the SIMMs by
the edges only.
