Replacing the fuses 3. Safety-check out (Only U.S.A. model) After correcting the original service problem perform the follwing safety check before releasing the set to the customer Connect the insulating-resistance tester between the plug of power supply cord and terminal GND on the back panel. Specifications: More than 10Mohm at 500V REF.NO.PART NO. DESCRIPTION NOTE : : 120 V model only : Asian model only for 120V : European model only : Asian model only for 230V : 220V model only This symbol located near the fuse indicates that the fuse used is show operating type, For continued protection against fire hazard, replace with same type fuse , For fuse rating, refer to the marking adjest to the symbol. Ce symbole indique que le fusible utilise est e lent. Pour une protection permanente, nutiliser que des fusibles de meme type. Ce demier est indique la qu le present symbol est apposre. This device employs a microprocessor to perform various functions and operations. If interference generated by an external power supply, radio wave, or other electrical souce results in accident which causes the specified operations and functions to pperate abnormally. To perform a result, please follow the procesure below. 1. Turn teh Power switch to on. 2. Press and the hold down the VIDEO-1 button, then press the STANDBY/ON button. 2. After clear is displayed, the preset memory and each mode stored in the memory, such as surround, are initialized and will return to the factory setting 3. Press the STANDBY/ON button. 4. Disconnect the power supply cord. 2. To initialize the unit 4. Memory Preservation This unit does not require memory preservation batteries. A built-in memory power back-up system preserves the contents of the memory during power failures and even when the unit is un-plugged. The unit must be plugged in order to charge the back-up system. The memory preservation period after the unit has been unplugged varies depending on climate and placement of the unit. On the average, memory contents are protected over a period of a few weeks after the last time the unit has been unplugged. This period is shorter when the unit is exposed to a highly humid climate. 5. Changing the AM band step When you change the band step, change the parts as shown below.

Front panel Power After plugging in the power cord into the rear panel and wall outlet, pressing this button connects the RDC-7 to the AC mains and turns it on. Before turning on the power, make sure all cables are properly connected. Turning on the RDC-7 may cause a momentary power surge that might interfere with other electrical equip- ment on the same circuit. If this is a problem, plug the RDC-7 into a different electrical circuit. Standby/On Pressing this button while the main power is turned on the STANDBY indicator lights up and the front display turns off. Pressing it again returns it to the standby state. This state turns off the display, disables control functions, and turns off all outputs to the main zone (those for the remote zone remain available). On and Standby indicator Master Volume The MASTER VOLUME knob is used to control the volume for the main zone. The volume for the remote zone (Zone 2) is independent. Open/Close Press this button to open and close the front door that covers the lower buttons. Display The DISPLAY button is used to display information about the current input source signal. Each time you press the display button, the screen changes to show you different information concerning the input signal. The screen changes as follows: Program format Sampling frequency Digital input Digital format Bass level Treble level. If the input source signal does not have any information for a particular screen, then that screen will be skipped. Displaying the data of the current input source Each display is explained below. Program format: Front channelSurround channel Sampling frequency: Source signal48 kHz Sampling frequency Digital input: The current input source is set for digital input at OPT1. LFE(Low Frequency Effect) Input Source Buttons (DVD, VIDEO 15, TAPE 1 2, AM, FM, PHONO, and CD) and Indicators These buttons are used to select the input source for the main zone. When an input source is selected, the indica- tor will light in blue. To select the input source for the re- mote zone (Zone 2) or recording out (Rec Out), first press the Zone 2 or Rec Out button, and then the desired input source button. Zone 2/Rec Indicator For Zone 2, the indicator above the selected input source button will light green. For recording, it will light red. Lower buttons in the front door Caution: The front door of the AV Controller is motorized. Use the open/close button to open or close the door. Manually opening or closing the door, or moving the AV Controller while holding the door, will cause the door to malfunction or break. Rec Out Press the Rec Out button to output to a recording compo- nent for recording purposes. After pressing the Rec Out button, press one of the input source selector buttons within 8 seconds to select the component to record to. When one is selected, the indicator above that button will light in red. To record from the same input source that you are using (that is selected for the main zone), press the Rec Out button twice in succession. Note: The Rec Out and Zone 2 buttons use the same circuit and therefore cannot be used at the same time. When Rec Out is selected, nothing is output from Zone 2. Zone 2 The RDC-7 includes a second signal path separate from the main one that can be used for a remote zone (Zone 2) or for making recordings. By connecting an additional amplifier or other video equipment to the Zone 2 outputs, you can output to a separate room an input source that is different from that being used in the main room. This al- lows you to watch one program in one room while some- body else is watching a different program in another. Press the Zone 2 button to enable output to the ZONE 2 outputs. After pressing the Zone 2 button, press one of the input source selector buttons within 8 seconds to select the input source for the remote zone. When one is se- lected, the indicator above that button will light in green. RDC-7 5 Front panel facilities Memory This button only operates when FM or AM is selected as the input source. This button allows you to preset fre- quencies for stations when using the FM/AM tuner. You can preset up to 40 stations (or frequencies) to be used with the PRESET buttons. Menu, , , Enter, , , Exit These buttons are used with the On Screen Display (OSD) menu. They also perform the same functions as the OSD MENU, (upper edge of ENTER button), (lower edge of ENTER button), (left edge of ENTER button), (right edge of ENTER button), ENTER, and EXIT RETURN buttons on the remote controller. Menu: Press to bring up the OSD menu. Exit: Press to exit the OSD menu when at the Menu Screen, or move to one screen previous to the one that is displayed if at any other screen. and : When selecting items in the OSD Menu, press these buttons to move the on-screen cursor (or the highlighted portion) upward and downward. and : When setting parameters in the OSD menu, press these buttons to select parameter values or modes. Enter: Press to display the screen for the selected item in the OSD Menu. Note for European models: These buttons are also used to set programs and finish scans when performing a PTY or TP scan with the RDS broadcasts. PHONES This is a standard stereo jack for connecting stereo headphones. The audio for the front right and left speakers are sent to the headphone speakers. When the headphones are plugged in, the listening mode automatically changes to stereo and output to the speakers is stopped. Front panel display Listening mode or digital input format indicators Multi function display Sleep indicator Input source format indicator Video display To use the same input source for the both the main and remote zones, press the Zone 2 button twice in succession. Note: The Rec Out and Zone 2 buttons use the same circuit and therefore cannot be used at the same time. when Zone 2 is selected, the currently selected input source is output from the recording terminal. Off When not using either Rec Out or Zone 2, press that but- ton and then press the Off button to turn off the signal. If the Rec Out or Zone 2 signal is turned on and the con- nected component is not turned on, the electric signal will still be sent through the circuitry and the excess load may cause deterioration of the audio signal.
