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).
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
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.
Your devices will always receive IR signals either directly from the
RC9500 or from the RX-77.
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. Mode Menu page appears.
2 Tap the “IR / RF” button to switch to IR/RF Setting mode.
The RC9500 displays the device list box
.
