Preparing Your Receiver Connecting the Antennas In many areas, the supplied indoor AM loop and FM antennas provide satisfactory reception. AM Antennas Antenna Tabs Base Assemble the included antenna’s base by swinging the base in the direction of the arrow and inserting the antenna’s bottom tabs into the base’s slot. Then attach the antenna wires to the LOOP ANTENNA terminals (bottom two terminals). Place the antenna on a flat surface and rotate it for the best AM reception.
Preparing Your Receiver Warning: To prevent injury, read and follow all cautions and warnings that accompany the outdoor antenna. For the best radio reception, use an outdoor antenna. Follow these steps to connect an outdoor FM antenna to the receiver using 75Ω coaxial cable. Note: If your antenna has 300Ω twin-lead cable, consult your local RadioShack store for the correct adapter. 1. Disconnect the supplied FM antenna from the receiver’s FM UNBAL 75Ω terminal. 2.
Preparing Your Receiver Using One Remote Control for More than One Unit Note: When you plug the cable into a component’s CONTROL IN jack, that component’s remote sensor does not function. CONTROL CONTROL OUT IN IN OUT Receiver Remote Control Other Component with OSR Mark If you also have an Optimus professional series CD player, VCR, or cassette deck with the OSR mark ( ), you can connect its CONTROL IN jack to the receiver so you can control all of your equipment with a single remote control.
Preparing Your Receiver Using the AC Power Outlet Your receiver has an AC power outlet that you can use to power another electronic device, such as a turntable, cassette deck, VCR, or so on. This switched outlet turns on and off with the receiver and provides a maximum of 100 Watts. Caution: Do not connect appliances with high power consumption, such as a heater, iron, monitor, or TV, to this AC outlet. Doing so can cause a risk of overheating and fire, and could damage the receiver.
Basic Operation Warning: To prevent possible hearing loss, turn VOLUME to MIN before you turn on the receiver or change the program sources. After you turn on the receiver or change the program source, adjust VOLUME to a comfortable listening level. Note: The controls on the remote control work the same as the buttons on the receiver’s front panel, though some are labeled differently. Follow these steps to use the receiver. 1. Press POWER to turn on the receiver’s power.
Basic Operation Balance Control The BALANCE control lets you adjust the sound balance between the left and right speakers. If you properly position the speakers and your listening area is centered between them, the center control setting is usually best (see “Positioning Speakers” on Page 5). For an unusual speaker placement, adjust BALANCE as follows: 1. Select TUNER. Then press FM/AM to select the FM band. 2. Press FM MONO so MONO appears.
Basic Operation Tuning the Radio You can tune your receiver manually or you can store stations in memory. Manual Tuning (Front Panel Only) Follow these steps to manually tune to a station. 1. Press TUNER. Then press FM/AM to select the desired band. When you select the AM or FM band, the receiver tunes to and displays the frequency last selected in that band. 2. Press SELECT so FREQ appears on the JOG MODE display. 3. Turn MULTI JOG to tune the desired station.
Basic Operation Using FM MONO To receive FM stations in stereo, press FM MONO so MONO disappears from the display. STEREO appears when the tuner receives an FM broadcast in stereo. You can improve the reception of weak FM stations by pressing FM MONO so MONO appears. This reduces noise while you listen to a weak FM station, but you get monaural instead of stereo sound.
Cassette Deck/VCR Features You can connect two cassette decks to the receiver. Selecting either VCR/TAPE 1 or TAPE 2 MONITOR lets you hear the playback from the cassette deck you connected to the receiver’s corresponding (VCR/TAPE 1, TAPE 2 MONITOR) jacks. Using the VCR/TAPE 1 and TAPE 2 Monitor Buttons Press VCR/TAPE 1. VCR appears on the display. You hear the playback from the cassette deck or VCR you connected to the receiver’s VCR/TAPE 1 jacks. Press TAPE 2 MONITOR.
Cassette Deck/VCR Features Playing and Recording Video Tapes You can connect four video sources to the receiver. If you connect a VCR to the VCR/TAPE 1 audio and video jacks, you can copy video tapes from one VCR to another and monitor the dubbing process. Playing a Video Tape To play a video tape, load the tape into the VCR connected to either VCR/TAPE 1, LD/SAT, or DVD/TV. Press the button (VCR/TAPE 1, LD/SAT, or DVD/TV) that corresponds to the jack the VCR is connected to.
Using Advanced Sound Options Your receiver has three special sound options: Dolby Pro Logic Surround, SFC Effects, and 5-D Theater. These special options enhance the sound you hear from a program source. Notes: • To get the full benefit from programs encoded with Dolby Surround Sound, you need a stereo VCR. • Dolby Surround does not operate correctly if the signal passes through a graphic equalizer.
Using Advanced Sound Options Sound Mode Adjustments (Remote Control Only) Note: If you do not use a center speaker, the monaural signals are only reproduced if you select PHANTOM. Center Mode Setting The center mode setting affects the center channel’s bass signals. It operates only when you select Dolby Pro Logic Surround Sound. Each time you press CENTER MODE on the remote control, the setting changes and the receiver displays: NORMAL, WIDE, PHANTOM, or 3CHLOGIC.
Using the Remote Control The remote control works up to a distance of about 23 feet, and within a 30-degree angle on either side of the receiver. Point the control at the receiver’s front panel and press the desired button(s). Many buttons on the remote control work the same as buttons on the receiver’s front panel. Use these buttons exactly as you would use the corresponding buttons on the receiver.
Using the Remote Control Tuner/TV Operation For these functions, set AUDIO/VIDEO to AUDIO to control the tuner, or to VIDEO to control a TV. You must train the remote control for TV functions (see “Training the Remote Control” on Page 25). 1– 9, 0/10 Press to select memory locations in the tuner mode. Press to directly enter the channel number in the direct tuning mode. See Page 17. STATION Tunes to the next higher or lower memory location with AUDIO/VIDEO set to AUDIO. See Page 17.

Select the AUDIO/VIDEO switch position. Set the switch to the position that best matches the function —to AUDIO for a CD player or tape deck or to VIDEO for a VCR or television. 3. Insert a pointed object (such as a straightened paper clip or the tip of a pen) into the LEARN hole on the STAV-3690’s remote control, then press and release.
Troubleshooting If the receiver is not working as it should, the following suggestions might help. If you follow the suggestions in this chart and the receiver still does not work properly, contact your local RadioShack store for assistance. Problem Power does not turn on. Cause Suggestion Power cord is disconnected. Plug in the power cord. Protection circuit is activated. Unplug the power cord, then plug it in again. The receiver does not respond to button presses.
Care and Maintenance Your STAV-3690 Audio/Video Receiver is an example of superior design and craftsmanship. The following suggestions will help you care for the receiver so you can enjoy it for years. Keep the receiver dry. If it gets wet, wipe it dry immediately. Liquids can contain minerals that can corrode the electronic circuits. Handle the receiver gently and carefully. Dropping it can damage its circuit boards and can cause the receiver to work improperly.
The FCC Wants You To Know Your receiver might cause radio or TV interference even when it is operating properly. To determine whether your receiver is causing the interference, turn off your receiver. If the interference goes away, your receiver is causing it.
