Operation Mode
Click on the
Advanced
tab at the top right (Figure 14). There are four
Operation Modes
from: Normal and Safe Mode Levels 1 – 3,
where Normal is the most aggressive and Safe Mode 3 the
safest.
The default operation mode is
Safe Mode Level 1
and should be used in almost all cases. If
you choose to operate with the Normal mode and your FLEX-5000 freezes up, you should revert to
Safe Mode Level 1. In very rare circumstances your PC may have internal latencies where Safe Mode
Level 1 does not work optimally with your system. In these cases, you should select either Safe Mode
2 or Safe Mode 3 to provide a stable environment to run the FLEX-5000.
Once you have verified that all is working well, you may fine tune the settings to best match your
system and favored modulation mode.

Technically these Operation Modes control how successfully the hardware driver recovers from buffer over and under runs.
Some hardware drivers and third-party applications issue what are called delayed procedure calls (DPCs). Higher Safe Modes
allow the driver to handle longer DPC latencies at the cost of more audio latency.
