Record button protection
The SRC-1600 has a protection
feature to prevent accidental
recording of videotapes, hard
disks or DVDs. The record button
must be pressed for two seconds
to begin recording.
NOTE: This only applies to the record button. If you
program another button to record, this safety
feature will not work for that button.
Punch thru
The punch thru function enables you to access
the VOL +/– controls of the TV or RECV device
without having to switch to that device. For
example, while you are watching a DVD you
can adjust the volume of your TV using punch
thru.
