DFU RC9500 Ver1_2.qxd 5/28/2004 10:33 AM Page 58 Reference 8. Using the RC9500 with Radio Frequency Warning To use the Remote Control with Radio Frequency (RF) you need a Marantz RX-77 RF Extender. This is an optional accessory for the RC9500. By default, the RC9500 uses infrared (IR) signals to operate devices. This means that you have to point the RC9500'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 RC9500 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 RC9500 or from the RX-77. User Guide Changing the IR / RF Settings All devices are set up by default to work with IR signals. To be able to operate one or more devices with RF signals, you have to change the RC9500's IR/RF settings for those devices. 1 Tap and hold the MODE icon in the LOWER TOOL BAR more than 3 seconds.
