4.1 Using the IR Transmitter
You can use the RC-IR3 IR transmitter to control the machine via the built-in IR
receiver on the front panel or, instead, via an optional external IR receiver (for
example, P/N C-A35M/IRR-50). The external IR receiver can be located up to 15m
away from the machine. This distance can be extended to up to 60m when used
with three extension cables (for example, P/N C-A35M/A35F-50).
Before using the external IR receiver, be sure to arrange for your Kramer dealer to
insert the internal IR connection cable (for example, P/N: 505-70434010-S) with
the 3.5mm connector that fits into the REMOTE IR opening on the rear panel.
Connect the external IR receiver to the REMOTE IR 3.5mm connector.
