Renaming Sources
By default, each Sender unit is assigned the name “Sender”. This can be
confusing when multiple Sender unit are used. However, this identifier can
be changed to reflect, for example, the source to which each Sender unit is
connected.
1. Point the IR Remote Control at the Receiver unit, press the MENU button,
select Modify Video Source Name, then press the OK button.
2. Select the source to rename from the menu by using the cursor keys:
