components using the remote control, as well as a detailed explanation
of all remote control operations. Once you have registered your compo-
nents with the proper setup codes, you'll be able to operate both this
receiver and your other AV components (TV, VCR, DVD player, LD pla-
yer, CD player, etc.) using the remote contro! supplied with this receiver.
VIDEO 2/MONITOR jacks (for VR-406/405/414/KRF-
V6030D/V5030D/V4530D :
The receiver's VIDEO 2/MONITOR jacks can be used in two different
ways. Make the appropriate setting for the component connected to
the jack when the receiver is turned on.
Use as a VIDEO 2 jack
You can connect a video deck or the like to these jacks and perform
video playback and recording. The initial factory setting is “VIDEO 2”.
Use as a MONITOR jack
You can connect a cassette deck or the like to these jacks and make
use of the deck’s monitoring function during recording. Alternately,
you can connect a graphic equalizer to these jacks to apply compen-
sation to the music signal.
To use the VIDEO 2/MONITOR jacks as MONITOR jacks, hold down
the MONITOR key of the main unit for more two seconds so that the
indication shown below appears.
