This manual is divided into four sections, Preparations, Operations,
Other, and Remote Control.
Remote Control (Separate booklet) (VR-407/VR-406/KRF-
V7030D/KRF-V6030D only)
Includes the “Quick Start Guide,” which shows you how to operate other
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.

Resetting the Microcomputer
If the microcomputer may malfunction (unit cannot be operated,
or shows an erroneous display) if the power cord is unplugged
while the power is ON, or due to some other external factor. If this
happens, execute the following procedure to reset the micro-
computer and return the unit to its normal operating condition.
+ Please note that resetting the microcomputer will clear the contents
of the memory and returns the unit to the state it was in when it left
the factory.
For U.S.A. and Canada
Unplug the power cord from the wail outlet, then plug it
back in while holding down the POWER key.
For other countries
With the power cord plugged in, turn the POWER key
OFF. Then, while holding down the ON/STANDBY key,
press POWER.

The DC voltage is an actual reading measured with a high impedance type volt-
meter as the AM/FM signal generator is specified to the conditions as shown in the
list below. The measurement value may vary depending on the measuring instru-
ments used or on the product. The value shown in (_) is actual reading measured in
the AM mode.
