Important Notice
Installing environment
This TV has “Space Tune” function which can adjust the
sound quality automatically according to TV and viewer’s
position. Using the line array speaker settings, it is also
possible to adjust the position that the sound reaches to
match the viewing position and circumstances. You can
enjoy a three-dimensional acoustic space by using the
upward-firing speakers, which reflect sound from the
ceiling, the line array speakers, and the left and right
speakers. The adjustment of the “Space Tune” function
automatically starts when the TV is turned on for the first
time after installing this TV and connecting with the
external equipment. Follow the on-screen instructions for
setting.
(p. 22)
“Space Tune” can be adjusted with [Space Tune Auto]
which adjusts automatically by using the voice control
microphone on the remote control to measure and
analyse a test tone played back, or with [Preset
Adjustment] where you enter the TV’s installation
environment and the sound quality is adjusted
accordingly.
≥
A loud sound (test tone) is output while setting with
[Space Tune Auto].
≥
This function is effective only for the sound from TV
speakers.
≥
The effect varies depending on the installing
environment.

Do not display any still part of the image
for a long period
In such cases the still part of the image remains dimly on
the screen (“image retention”). This is not considered a
malfunction and is not covered by the warranty.
≥
Typical still image parts:
• Still images shown continuously on the same area
(ex. channel number, channel logo, other logos or
title image, etc.)
• Still or moving pictures viewed in
4:3 or 16:9 aspect ratio, etc.
• Video games
≥
To avoid image retention, the screen saver may be
activated (OLED logo moves) or the on-screen
message may move after a few minutes if no signals
are sent or no operations are performed.
≥
Set [Logo Luminance Control] to [Max] to avoid image
retention.
[eHELP] (Search by Purpose > Watching > For best
picture > Screen Settings)
≥
To avoid image retention, the screen may become dim
when the motionless image is displayed. This is not a
malfunction. The brightness of the screen returns to
the previous level when the active image is displayed.
≥
Be sure to turn the TV off with the remote control to
perform the panel maintenance. During the panel
maintenance, LED turns to orange. (p. 21) The
maintenance works as necessary.
≥
Set aspect ratio to [4:3 Full] for 4:3 image. For details,
refer to [eHELP] (Search by Purpose > Watching >
For best picture > Aspect).
