Connecting a Home Video Game System etc. (AV-IN4)
Connecting External Devices (Continued)
Note:
• Game devices must always be connected to the input terminal of the main unit. If a game device is connected to the Wireless Centre, you
cannot enjoy the game comfortably because of a delay in the transmission of pictures and sound.
• When connecting to both the VIDEO input and S-VIDEO input terminals for AV-IN 4, priority is given to the S-VIDEO input terminal.
• When signals from external devices connected to the Wireless Centre do not appear to be transmitted to the main unit properly, connect
the external devices to the AV-IN4 terminal of the main unit.

• The radio waves used by the product are high frequency, so that
there are features such as direct advance travelling, reflection,
refraction, diffraction, interference etc., similar to that of light.
The strength of the waves therefore varies depending on the
location, which may cause the pictures and sound to become
unclear, become wavy, or stop.
• Is the distance between the Wireless Centre and the television
product too far? Use within a range that the radio waves can
reach.
• Are you at a location that is particularly susceptible to electrical
noise?.
• Set “Distance” to “far”.
• The product utilises wireless transmissions, so that fast moving
images may become distorted, but this is not a malfunction.
• Are there any devices operating in the vicinity of the product
such as Bluetooth devices, or wireless LANs, or microwave
ovens, etc. that utilise the same frequency band (2.4 GHz) as
the product?
• There are good and bad positions in terms of wave conditions
with regards to the influence of obstacles and reflectors. Try
changing the location of the television product slightly.
• Is the video controller connected?
• Is the transmitter of the video controller facing the infrared
receiver of the remote control for the VCR?
• Does the VCR work when operating the remote control by
directly facing the VCR? (If the VCR is still not working, it can be
considered that the battery of the remote control has run out.)

Troubleshooting (Continued)
■ Cautions regarding use in high and low temperature environments
• When the unit is used in a low temperature space (e.g. room, office), the picture may leave trails or appear slightly delayed.
This is not a malfunction, and the unit will recover when the temperature returns to normal.
• Do not leave the unit in a hot or cold location. Also, do not leave the unit in a location exposed to direct sunlight or near a
heater, as this may cause the cabinet to deform and the LCD panel to malfunction.
(Storage temperature: –20°C to +60°C (–4°F to +140°F))
Problem
Check item
Blocks of noise appear on the pictures.
Sound becomes interrupted.
Pictures are suddenly stopped and
sound is interrupted.
Pictures and sound cannot be received.
The VCR will not operate even though
the remote control is operated by facing
towards the TV main unit.
■ It is not a malfunction in the following cases.
• There are cases where reception of pictures is not good because of the distance between the main unit and Wireless Centre,
or obstacles. Install the main unit and Wireless Centre where you can get better pictures by changing the installation location
or removing obstacles.
• There may be bad reception of pictures if a microwave is being used nearby.
• Microwave units and the use of the so called “blue tooth function” (W LAN) on mobile phones or notebooks may impair the
quality of the transmission. If this is the case, switch these devices off.

Troubleshooting (Continued)
Problem
Check item
• The reception may be weak.
• The quality of the broadcast may also be bad.
• Make sure the antenna is facing the correct direction.
• Make sure the outside antenna has not been disconnected.
• Make sure the antenna is facing the correct direction.
• Broadcast waves may be reflected from adjacent mountains or buildings.
• There may be interference from automobiles, trains, high-voltage lines, neon lights, etc.
• There may be interference between the antenna cable and power cable. Try positioning
them further apart.
• Is the unit receiving interference from other devices?
Transmission antennas of radio broadcasting stations and transmission antennas of
amateur radios and cellular phones may also cause interference.
• Use the unit as far apart as possible from devices that may cause possible interference.
