Summary
At 500.000 exposures on the RS shutter it is recommended to send in the lens for service
In-Depth
After an RS shutter reaches 500.000 captures a service warning is shown when camera is connected to iX Capture. This message will also start to show and pop-up every 100 captures. This happens on iXM firmware prior to version 4.00.35. To avoid the message every 100 captures please update firmware to 4.00.35 or newer, this will then only prompt when first connected to the software.
Note: There is no way to remove the warnings on an iXU unit other than physically exchanging the shutter.
