This manual is divided into four sections, Preparations, Operations,
Other, and Remote Control.

Remote Control (Separate booklet) (VR-407/VR-406/KRF­V7030D/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 compo­nents with the proper setup codes, you’ll be able to operate both this
receiver and your other AV components (TV, VCR, DVD player, LD pla­yer, CD player, etc.) using the remote control supplied with this receiver.

The manual covers the VR-407, VR-406, VR-405, VR-414, KRF­V7030D, KRF-V6030D, KRF-V5030D, and KRF-V4530D. Items such
as functions, number of jacks, and remote control details differ some­what between these models. To confirm the functions available on the
model you have purchased, refer to the table below.

VIDEO 2/MONITOR jacks (for VR-406/405/414/KRF­V6030D/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 compen­sation 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.

• At the same time the setting is switched to “MONITOR,” the audio
input source switches to tuner and the video input source switches
to VIDEO 1.

• To switch the setting back to “VIDEO 2,” once again hold down the
MONITOR key for two seconds or more.

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 micro­computer and return the unit to its normal operating condition.

Unplug the power cord from the wall outlet, then plug it
back in while holding down the POWER key.

• 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.

With the power cord plugged in, turn the POWER key
OFF. Then, while holding down the ON/STANDBY key,
press POWER.

CAUTION: For continued safety, replace safety critical components only with manufacturer's recommend-

ed parts (refer to parts list). indicates safety critical components. For continued protection against risk

of fire, replace only with same type and rating fuse(s). To reduce the risk of electric shock, leakage-current

or resistance measurements shall be carried out (exposed parts are acceptably insulated from the supply
