Precautions when using the
Omni-Directional RF Remote
Control
Precautions regarding wavelength
• This remote control is designed to prevent
other persons from eavesdropping on the
transmitted signals, but precautions
should nonetheless be taken against the
chance that other persons’ could intercept
and listen to the signals transmitted. Given
that this remote control produces radio
wave transmissions, another person could
deliberately use a receiver to attempt to
intercept such transmissions. As a result,
this device should not be used to play
important transmissions demanding
privacy.
This remote control utilizes the 2.4 GHz
frequency band. This band is also used by a
variety of other devices as noted below. In
particular, devices not often cognizant to the
user are listed in item 2.
1 Examples of common devices utilizing the
2.4 GHz band:
• Cordless phone
• Cordless facsimile
• Microwave oven
• Wireless LAN router
• Wireless AV device
• Wireless controllers for games
• Microwave therapeutic devices
• Bluetooth wireless technology devices
2 Other devices using 2.4 GHz:
• Shoplifting-prevention systems
• Amateur wireless radio
• Distribution control systems at factories
and warehouses
• Railway and emergency vehicle wireless
identification systems
When such devices are used simultaneously
with this remote control, signal interference
may occur, resulting in signal dropouts.
To improve reception quality, try the following:
• Turn off the other device emitting radio
waves.
• Place the interfering device farther away
(Move both the remote control and RF
adapter away from the interfering device).
Do not use this remote control in the following
locations, since transmission interruption may
result:
• Locations where another device using the
same 2.4 GHz frequency is being used,
such as a Bluetooth wireless technology
device or wireless LAN, or in the vicinity
where the magnetic field, static electricity,
or radio wave interference from another
device may occur (depending on the
environment, radio waves may not transmit
effectively).
• Move the radio farther away.
• If visual noise appears on the television
screen, it is possible that this remote
control is producing adverse influence on
the antenna input of the television, video
device, BS tuner, or CS tuner. Move this
remote control farther away from the
antenna input of the affected device.
Usable range
• Designed for use only within private homes
(signal transmission distance may be
reduced due to room design or conditions).
In the following cases, this remote control
cannot operate due to poor or erratic radio
wave transmission.
• When signal transmission is blocked by a
wall or floor constructed of ferro-concrete
or metal.
• Nearby large metal furniture objects
• In large crowds of people, or near
obstructive buildings.
