2.4.5 SAFETY

When the system is connected, it may be dangerous to touch the terminals.

Additionally, dangerous parts may be exposed when covers are opened or

when protective components are removed. The system should not be used

until it is completely installed.

To increase system capacity with expansion cards prior to handling, modify

its connections or replace equipment; the power supply should be shut off

and the inputs disconnected from the CVMk2. Handling the system while it

is powered up is dangerous.
