CORRECT USE OF THE PRODUCT
Precautions Regarding Radio Waves
■ Do not use the product at the following locations. There may be cases where noise occurs or transmission/reception is
not possible.
• Locations where magnetic fields, electrostatic or interference occurs due to devices such as Bluetooth, wireless LANs, or
microwave ovens etc. that utilize the same frequency band (2.4 GHz) as the product. (There may be cases where radio waves
cannot reach depending on the environment.)
• Keep the product away from a radio devices during use. (There may be cases of noise interference.)
■ Under the same frequency band as the product uses, in addition to Bluetooth, wireless LANs, and microwave ovens
etc. that utilize the same frequency band (2.4 GHz) as the product, operation can also take place at on-site radio
stations that require a license for mobile object identification used in factories and manufacturing lines etc. and
specified low power radio stations.
• Before using the product, make sure that there is no on-site radio stations for mobile object identification or specified low power
radio stations operating in the vicinity of the product.
• If there is any interference occurring to on-site radio stations for mobile object identification due to the product, stop using the
product immediately.
Regarding Range of Usage
■ The product is limited to domestic use.
(There is a possibility that transmission distance may become short depending on the communication environment.)
■ In the following cases, reception may become bad or impossible, which may cause sound and pictures to be inter-
rupted (pictures and sound are stopped), or blocks of noise to appear.
• Using the product in a reinforced concrete building such as a condominium building or a house of a metal structure.
• Using the product at locations near large-scale metallic furniture.
• Using the product in a crowd of people or close to buildings or obstacles, etc.
• Using the product at locations where magnetic fields, electrostatic and interference occur due to devices such as Bluetooth,
wireless LANs, or microwave ovens, etc. that utilize the same frequency band (2.4 GHz) as the product.
■ Regarding reflected radio waves
• Radio waves that reach a television receiver are radio waves (direct waves) directly transmitted from a transmitter and radio
waves (reflected waves) arriving from various directions as a result of being reflected by walls, furniture, or buildings etc. There
are good and bad positions in terms of wave conditions due to the influence of these reflected waves, which may cause poor
picture reception. In this case, try changing the location of the TV receiver slightly. There are cases where pictures and sound
are distorted or interrupted due to the reflected waves as a result of a person passing over or approaching between the transmit-
ter and the television receiver.
When a signal other than a regular signal is input
• When a signal other than a regular signal that is incompatible with this unit is input, the screen may freeze, but this is not a
malfunction.
• When a signal other than a regular signal is input from the Antenna, AV-IN1, AV-IN2, or AV-IN3 terminals, reception may be bad
depending on the performance of the Wireless Center, and the message “THIS SIGNAL IS NOT COMPATIBLE” will display.
• Signals compatible with the Wireless Center are as follows:
H: 15.625 kHz / V: 50.0 Hz, 59.52 Hz
H: 15.73426 kHz / V: 59.94 Hz
(Note: Reception may be available with AV-IN4.)
Precaution Regarding Electromagnetic Wave Disturbance
• If electric devices, such as a cellular phone, are used near this unit, electromagnetic wave disturbance may occur between
apparatus. In such cases, the picture quality may decrease and noise may appear.
