To select any external program source that you connect to the receiver, press the corresponding source button-TAPE MONITOR, CD, AUX, PHONO, or TV/VCR. The display shows the selected source. Caution: To prevent accidental overload, turn VOLUME to 0 before you select program source. Note: Be sure to read the instructions for all of your system's components. SETTING THE VOLUME The VOLUME control is labeled with numbers so you can reference a number for a specific volume level. Turn VOLUME clockwise to increase the volume and counterwise to decrease it. Note: When you increase or decrease the volume with the remote control, the volume control moves clockwise or counterwise, respectively. BASIC OPERATION WARNING: To prevent possible hearing loss, turn VOLUME to 0 before you turn on the receiver or change the audio source. After you turn on the receiver or change the audio source, adjust VOLUME to a comfortable listening level. Follow these steps to use the receiver. 1. Press POWER to turn on the receiver's power. The STANDBY indicator goes off and the PROTECTION indicator lights. After a few seconds, the PROTECTION indicator goes off. (See "Built-in Protection Circuits.") 2. Select the speakers as follows. Press in A or B to turn on either pair of speakers for a two- speaker effect. Press in A and B to turn on both pairs of speakers for a four- speaker stereo effect. To turn off a pair of speakers, press out the corresponding button to release it. Note: If you connect only one pair of speakers, press only the corresponding SPEAKER (A or B) button. Otherwise, you mute the sound from the connected speakers. 3. Select the audio source as follows: To listen to a tape, press TAPE MONITOR so the TAPE MON indicator lights. To listen to a source other than a tape deck, be sure the TAPE MON indicator is off (if necessary, press TAPE MONITOR so the indicator goes off). Then press PHONO, CD, AUX, TV/VCR, AM, or FM to select the audio source. 4. To tune to a radio station, press TUNE > or TUNE < to tune up or down in the selected band. Note: See "Tuning to a Radio Station" for information about memory tuning. 5. Adjust VOLUME. To boost the bass and treble when listening at low volumes, press in LOUDNESS. 6. Press POWER to turn off the receiver. The STANDBY indicator lights. TUNING TO A RADIO STATION You can use manual, search, or memory tuning to select a radio station. Notes: If you are using the supplied AM loop antenna, reposition it for the best AM reception. TUNED appears on the display when the receiver tunes to a strong frequency. FM STEREO appears on the display when the signal is stereo. Manual Tuning Follow these steps to manually tune to a radio station. 1. Press AM or FM to select the band. The display shows the selected band. 2. Press TUNE > or TUNE < to tune up or down the band. The display shows the selected frequency. Search Tuning Use search tuning to quickly find strong AM or FM stations. 1. Press AM or FM. 2. Press AUTO SEARCH to turn on the search function. AUTO appears on the display. 3. Press TUNE < or TUNE >. The receiver searches down or up the selected band until it finds a strong radio frequency. TUNED, FM STEREO, or both appears on the display. Manual and Search Tuning Hints Use manual tuning to locate a weak FM station. If reception for the weak station is poor, press FM MONO so MONO appears on the display. The sound is no longer in stereo, but reception improves. The receiver displays FM frequencies in 0.2 megahertz (MHZ) intervals and AM frequencies in 10 kilohertz (kHz) intervals. If you press TUNE > when display is at the top of the frequency range (AM -1710 kHz, FM-107.9 MHz), the display returns to the bottom of the range (AM-520 kHz, FM-87.5MHz). If you press TUNE < when the display is at the bottom of the frequency range, the display returns to the top of the range. When you select the AM or FM radio band, the receiver displays the last frequency selected on that band. MEMORY TUNING The memory tuning feature lets you instantly tune to a frequency you stored in one of 30 memory locations. Each location can hold an AM or FM frequency. To store a frequency, follow these steps. 1. Press AM or FM. 2. Use manual or search tuning to select the frequency you want to store. 3. Press MEMORY. MEMORY flashes on the display for about 5 seconds. 4. While MEMORY flashes, press the memory preset button(s) (1-30) to select the desired memory location (for example, press 1 and 4 for location number 14). This stores the frequency. To tune to a stored frequency, press the desired memory location number button(s). If you use the remote control to tune to a frequency, press TUNER first, then press the desired memory location number. Notes: When you store a frequency in a memory location that already contains a frequency, you replace the previous frequency. If the receiver is disconnected from AC power for more than three days, it loses all the stored frequencies. Scanning Memory Stations Press MEMORY SCAN to scan the frequencies stored in memory. The receiver stops for about 5 seconds at each memory location that contains a frequency so you can hear a station before scanning resumes. To stop scanning, press MEMORY SCAN again or any of the memory preset buttons. RECORDING A TAPE If you connect a tape deck to the receiver as described in "Connecting Audio Sources," you can record one of the receiver's other audio sources on the deck. Press PHONO, TV/VCR, CD, AUX, AM or FM to select the audio source you want to record. Then begin recording. To ensure that the tape deck is receiving the signal, press TAPE MONITOR so the TAPE MON indicator lights. You hear the recording from the tape deck as it is made, if your tape deck has a tape monitoring function. If you want to listen directly to the audio source as you record, press TAPE MONITOR so the TAPE MON indicator is off. USING HEADPHONES A good pair of stereo headphones is a valuable addition to a home stereo system. They provide convenient private listening and an enhanced stereo effect. Your receiver's front panel PHONES jack accept any low-impedance stereo headphones with a 1/4-inch plug. Before buying your headphones, wear them long enough to be sure they are comfortable. To listen through headphones, insert the 1/4-inch plug of a pair of low- impedance stereo headphones (not supplied) into the receiver's PHONES jack. For private listening, turn off the speakers by pressing SPEAKERS A/B so both buttons are in the out position. Listening Safely To protect your hearing, follow these guidelines when you use headphones. Turn VOLUME to 0 before you begin listening. After you begin listening, adjust the volume to a comfortable level. Do not listen at extremely high volume levels. Extended high-volume listening can lead to permanent hearing loss. Once you set the volume, do not increase it. Over time, your ears adapt to the volume level, so a volume level that does not cause discomfort might still damage your hearing. SLEEPTIMER You can set the receiver to automatically turn off after 10, 20, 30, 60 or 90 minutes. To start the sleeptimer, press SLEEP button until the desired turn-off time appears on the display. ADJUSTING THE SOUND Use the following controls to adjust the sound to suit your listening preferences. Surround Button If you are using 4 speakers, your receiver's surround effect provides a fuller, more spacious sound for your stereo programs. Press SURROUND to turn on the surround feature. To turn off the surround feature, press SURROUND again. BALANCE The BALANCE control lets you adjust the balance between the left and right speakers. This control affects both pairs of speakers (A and B). If your speakers are properly positioned and your listening area is centered between the speakers, the BALANCE control's center setting is usually best. For unusual speaker placements, adjust the balance as follows: 1. Tune to an FM station. 2. Press FM MONO so the MONO indicator lights. 3. Adjust BALANCE until the sound seems to be coming from a point halfway between the two speakers. 4. Press FM MONO so the MONO indicator goes off to return to normal FM reception. Bass and Treble Adjust the BASS control to increase or decrease low frequency sounds, such as those from a bass drum or bass guitar. Adjust the TREBLE control to increase or decrease high frequency sounds, such as those from a violin, piccolo, or cymbals. Mute Function Press MUTE on the remote control to silence the speakers. MUTE appears on the display while the muting function is on. To turn off the mute function, press MUTE so MUTE disappears from display. (LB/smc-05/18/94)
