Reference 7. Using the RC5400 with Radio Frequency Warning To use the Remote Control with Radio Frequency (RF) you need an Marantz RX-77 RF Extender. This is an optional accessory for the RC5400. By default, the RC5400 uses infrared (IR) signals to operate devices. This means that you have to point the RC5400 s IR sending eye towards the devices you re operating. IR signals have an operating distance of approximately 10 meters (33 feet). IR signal You can choose to operate devices using Radio Frequency (RF) signals instead of IR signals. RF signals can, unlike IR signals, go through obstacles like furniture or walls. The RF signals sent out by the RC5400 are picked up by the RX-77 RF Extender. The RX-77 translates the RF signals in IR signals and sends the IR signals to the RF signal appropriate devices. Therefore, the RX-77 has to be placed near the devices you re operating with the RX-77 s sending eye pointed to the device. IR signal RX-77 Your devices will always receive IR signals either directly from the RC5400 or from the RX-77.
