Signal Processor Frame Module Precautions
WARNING
When Signal Processor Frame power is turned off, current switcher state
data will be lost. When power is restored, the switcher will reset to either a
user-defined default state, or a GVG factory default state (setup in the Define
Defaults Menu). If you wish to save the current switcher state, “learn” the
state to an empty E-MEM register. When the switcher is turned back on, you
can recall that E-MEM register to return to the previous state.
WARNING
High current capability is present in the Signal Processor Frame. Remove all
rings and other jewelry when working on extended circuit modules, and use
caution when using metal tools in the vicinity of power buses.
CAUTION
Many of the circuit modules in the Signal Processor Frame are sensitive to static
discharge. Failure to use proper static-control procedures while working on circuit
modules may cause data loss and/or electrical destruction of static-sensitive
devices.
