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. TEXT.
Note on the TV SYSTEM button
•
The TV SYSTEM button is not used on your TV (KV-J21PF1
only).
Notes
•
When you switch 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
POWER on the TV to switch off the TV for five minutes and
then switch it on again.
WARNING
Do not install the appliance in a confined space, such as
a bookcase or built-in cabinet.
