BUTTON DESCRIPTION
Device Buttons:
[TV] [VCR] [C/SAT][DVD]
[AMP] [CD]
. These buttons are used to select the
device to control. For example, the
[C/SAT]
button switches the remote to cable or satellite
mode and the remote control functions control the
cable box. Pressing
>79@
switches the remote to
TV mode. Some controls may function even when
their normal device is not selected (Punch
Through). For example, when in cable box mode,
the volume controls may still work with the televi-
sion, and the VCR controls may still control the
VCR. The availability of this feature depends on
the type of TV, VCR, cable box, etc.
[Power]
This button is used to turn the TV, VCR,
cable box etc. on or off.
