6. Using the Remote Control
with Radio Frequency
Warning To use the Remote Control with radio frequency (RF) you need an RF Extender,
which is only included with the RC9200. It is an optional accessory for the
RC5200.
By default, the Remote Control uses
infrared (IR) signals to operate devices.
This means that you have to point the
Remote Control's sending eye towards
the device you're operating. IR signals
have an operating distance of 10 meters
(33 feet).
You can choose to operate devices
using radio frequency (RF)
signals instead of
IR signals. RF signals have an
operating distance of
approximately 20 meters (66 feet)
in house and can, unlike IR signals,
go through obstacles like furniture
or walls.
The RF signals sent out by the Remote Control are picked up by the RF Extender.
The RF Extender translates the RF signals in IR signals and sends the IR signals to
the appropriate device. Therefore, the RF Extender has to be placed near the
device you're operating with the RF Extender's sending eye pointed to the device.
Your devices will always receive IR signals either directly from the Remote Control
or from the RF Extender.
