signal for at least 350 ms. After configuring a setting, wait at least 1 second before
configuring the next setting.

After a setting is made, it may take about 3 seconds for the operation to finish. If you
configure subsequent settings before the initial operation finishes, only the last setting will
take effect. All settings in between will be discarded. (In the following example, control 2 will
be discarded.)
