instructions below. If the problem persists, contact Shure’s Applications Group.

Unable to switch device presets from the computer:
• Check the device's security level. In order to switch presets from the computer, the device must be set
either to security level 1, or customized level 2. For more information, refer to the Security section on
page 85.
• If preset changes via control input pins are enabled, the unit will not respond to preset changes via the
software. To solve the problem, disable the control pins for preset change in the Control Pin window.
For more information, refer to the Preset Control Block section on page 78.
Software spontaneously changes from Live Mode to Design Mode:
When you are working in Live Mode and use devices connected to the control inputs to change
presets, mute channels or adjust volume, the software may switch to Design Mode. This is normal
operation. Monitoring external device control via the software is not currently a supported feature. This
situation is less likely to occur with faster computers.
