PUNCH-THROUGH
The punch-through feature lets you alternately
control two different devices without pressing
the device keys for each one.
A TV is often the only device that uses the vol-
ume keys. Punch-through allows you to control
the TV’s volume while the 4-in-One is in any de-
vice mode. With punch-through on, if you press
VCR
and use your volume keys, the 4-in-One
will control the TV’s volume instead of the
VCR’s.
