Speedlite Transmitter ST-E3-RT (ver3) locked in SENDER-mode

Hi,

My new ST-E3-RT (version 3) has somehow locked in SENDER mode and it seems there is no way to put it into MASTER mode.

The transmitter opening-screen displays: ETTL, Ratio Off, SENDER, ALL and 0(ratio)

Please advise me how to change SENDER to MASTER

Canon has changed the term "Master" with Sender on newer products starting with the EL-1. Master and Sender are the same thing no difference. Now for off camera speedlites Canon has changed the term "Slave" with Receiver. On newer products such as the EL-1. There is no difference between Slave and Receiver and they function the same way as they used to except for a different name.
