Why do I receive a warning about indexing a scalar function handle when using Data Acquistion Toolbox 2.6 (R14SP2)?

I am using the Data Acquisition Toolbox to create and configure a device object for acquisition. Upon issuing a command to set the property of my device object, I receive the following warning:

 Warning: To support parenthesis notation for invocation, "indexing" a scalar

function handle by ":" will continue to work in R14, but may be illegal or may

work differently in R15.  To prepare for R15, and to avoid this warning,

use cell arrays of function handles instead of arrays.  For more information,

type 'help function_handle' and see the section at the end entitled

Note on Backward Compatibility.

This issue has been fixed in Data Acquisition Toolbox 2.7 (R14SP3). For previous releases, please read below for any possible workarounds:

This warning is a bug in the Data Acquisiton Toolbox in the way that the class of function callbacks is interpretted. This warning should not occur, and is harmless. You should be able to safely supress this warning using the WARNING function.

For more information on suppressing warnings, issue the following command at the MATLAB command prompt:
