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, youll 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 control supplied with this receiver. The manual covers the VR-407, VR-406, VR-405, VR-414, KRF-V7030D, KRF-V6030D, KRF-V5030D, and KRF-V4530D. Items suchas functions, number of jacks, and remote control details differ some-what between these models. To confirm the functions available on themodel you have purchased, refer to the table below.Model nameRemoteTerminalControlSpeaker outVIDEO 3 jacksFront inputVR-407RC-R06092 systemsEquippedEquippedKRF-V7030D(A, B)VR-406RC-R06092 systemsNot equippedNot equippedKRF-V6030D(A, B)VR-405/414RC-R05091 systemNot equippedNot equippedKRF-V5030D/V4530DMemory back up functionPlease note that the following items will be deleted from the unit's memory if the power cord is disconnected from the AC outlet for approximately 3 days.

Make the appropriate setting for the component connected tothe jack when the receiver is turned on.Use as a VIDEO 2 jackYou can connect a video deck or the like to these jacks and performvideo playback and recording. The initial factory setting is “VIDEO 2”.Use as a MONITOR jackYou can connect a cassette deck or the like to these jacks and makeuse of the decks 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/MONITORjacks as MONITORjacks, hold downthe MONITORkey of the main unit for more two seconds so that theindication 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 MONITORkey for two seconds or more.TUNEDAUTOFMMHz AMkHzPRO LOGIC3 DOWN MIXDIGITALS.DIRECTDSPAUTO SOUNDLFECSRSLSTI.VOLBCLIPMUTERDSEONPTYTPTANEWSSTEREOST.MEMOSWRLSPAMONITORMONITORResetting the MicrocomputerIf the microcomputer may malfunction (unit cannot be operated,or shows an erroneous display) if the power cord is unpluggedwhile the power is ON, or due to some other external factor.
