TECH NOTES:

1. Never turn the unit power on without all boards and cables
securely screwed down to the rack as well as the heads.
The system will not operate without the boards screwed in.

2. Never plug or unplug the head cables with the unit's
power on.  Blown boards will almost surely result.

3. Never remove boards with the power on.

4. Grounded wrist straps are a must whenever handling
bare printed-circuit-boards.
