Note on the remote commander
The supplied remote commander is used on several models of
the TV.  If you do not find instructions for some controls that
are on the remote commander, that means your TV does not
employ the features of those controls, e.g. 
 and SOUND
MODE.
Notes
When you turn on the TV, you may hear the “boon” sound
that is caused by the demagnetization of the TV. This does not
indicate a malfunction.
The picture color may become abnormal if you change the
direction of your TV. To obtain the normal picture color, press
U
 on the TV to turn off the TV for five minutes and then turn
it on again.
Design and specifications are subject to change without notice.
All contents in the instruction manual are subject to change
without notice.
