REMOTE CONTROL SIGNALS: UHF AND IR
Theremotecontrolusesboth Ultra High Frequency (UHF) radio
signals and Infrared (IR) light signals to control the receiver
but uses only IR signals to control other devices.
• IR signals travel only short distances (40 feet or less),
and can’t go through walls or other solid objects.
You must point the remote control right at the device
you want to control, with no objects to block the signal path.
• UHF signals travel long distances (100 feet or more) and can
go through walls and other solid objects. Because UHF signals
travel so far, the receiver may respond to signals from other
nearby remote controls. To handle this problem, see Change the
Address on page 9. If this doesn’t work, see Install an Attenuator
on page 4.
• You need to attach the UHF remote antenna to the receiver’s
back panel UHF REMOTE ANTENNA input so you canuse the
UHF capabilities of the remote (as shown in the diagram below).
Note: Set the antenna straight up so you can use the remote
from as far away as possible. Don’t let the antenna touch
anything.
Note:If you don’t attach theantenna,you can still use theremote
to control the receiver at short distances. This is because
the remote sends both IR and UHF signals to the receiver.
