<span style="font-size: 9pt; font-family: Verdana;"]I believe this leaves me with two options:
<p style="margin-left: 0.5in; text-indent: -0.25in;"]<span style="font-size: 9pt; font-family: Verdana; color: black;"]<span>1.<span style="font-style: normal; font-variant: normal; font-weight: normal; font-size: 7pt; line-height: normal; font-size-adjust: none; font-stretch: normal; font-family: 'Times New Roman';"] <span style="font-size: 9pt; font-family: Verdana;"]Set the C.Fn-01 to &ldquo;OFF&rdquo; which would leave the flash on until I physically turned the switch on the back of the flash to &ldquo;OFF&rdquo;
<p style="margin-left: 0.5in; text-indent: -0.25in;"]<span style="font-size: 9pt; font-family: Verdana;"]<span>2.<span style="font-style: normal; font-variant: normal; font-weight: normal; font-size: 7pt; line-height: normal; font-size-adjust: none; font-stretch: normal; font-family: 'Times New Roman';"] <span style="font-size: 9pt; font-family: Verdana;"]Set the &ldquo;MODE&rdquo; switch on the back of the flash to &ldquo;Slave&rdquo; so that the flash <span style="font-size: 9pt; font-family: Verdana;"]Auto power off after 60 minutes.


<span style="font-size: 9pt; font-family: Verdana;"]My question is this:


<span style="font-size: 9pt; font-family: Verdana;"]Will setting the mode on my <span style="color: black;"]Canon 430EX Speedlites to &ldquo;Slave&rdquo; create any problems when trying to trigger them via RF trigger?<span> My concern is that the flashes will not fire via RF triggers if they are in the slave mode and expecting an IR trigger.<span> Any thoughts?<span> Any concerns that this could damage the flash?

Why is this unacceptable? The RF trigger will wake up the flash when it's time, if not even keep the flash awake while the RF trigger unit is powered. Most likely, your remote flashes will be set to a manual zoom position, so they won't have to zoom-cycle.


As well, your RF trigger will make the flash think it's sitting on a camera, and as soon as a flash receives a 'camera' signal, it will drop out of Slave mode.


If the RF trigger doesn't keep the flash alive, then you may want to set CFn01 to off.
