OPERATIONS Automatic Seek Tuning 1. Turn the volume control knob of the amplifier to the minimum level and turn on the amplifier. Then, select the tuner function on the amplifier according to its owner's manual. 2. Press the "POWER" switch and STATION DISPLAY wil l indicate the FM or AM frequency. 3. Select FM or AM reception using the "FM/AM" switch. 4. Set the "tuning" mode selector to the "seek/muting" po- sition. 5. Slightly rotate the "TUNING" switch knob clockwise or counterclockwise to start seeking the broadcast station. To select a higher frequency than that indicated by the STATION DISPLAY, turn the knob clockwise (to the "up" direction). To select a lower frequency, turn the knob counterclockwise (to the "down" direction). The frequency changes until a broadcasted signal is tuned in, and the automatic seeking stops at that station. The "SIGNAL STRENGTH" indicator progressively illuminates according to the reception level, and the "TUNED" indicator wil l illuminate to indicate that the station is tuned in. When receiving an FM stereo broadcast, the "STEREO" display will illuminate automatically. 6. If the tuned frequency is not the desired broadcast station, slightly rotate the "TUNING" switch knob clockwise or counterclockwise to resume automatic seeking. 7. In an area of poor signal strength, additional noise may be created when a weak signal is received in stereo. In this case, the "mode" switch should be depressed to the "mono" position. 8. When the desired station is selected, advance the volume control knob of the amplifier to a comfortable level. NOTE: When a broadcast is weak, automatic seek tuning to that frequency may not be possible. In this case, place a dedicated antenna outdoors or tune manually as described in the following section. Manual Tuning Manual tuning is useful when the desired station is too weak to be picked up in the automatic seek tuning mode. 1. Set the volume control knob of the amplifier at minimum level and press the "POWER" switch. 2. Select FM or AM reception using the "FM/AM" switch. 3. Depress the "tuning" mode selector to the "manual" po- sition. 4. Depress the "mode" switch to the "mono" position. 5. Rotate the "TUNING" switch knob clockwise (to the "up" direction) or counterclockwise ("down" direction) to find the desired broadcasting station. The best tuning is obtained when many segments of the "SIGNAL STRENGTH" indicator light up. If it is the desired station, leave the "TUNING" switch at that position. The station wil l then be locked in. 6. When the desired station is selected, advance the volume control knob of the amplifier to a comfortable level. Preset Memory This feature enables the selection of one of sixteen AM or FM broadcasts by simply pressing the PRESET and "shift" buttons. In order to use this feature, broadcast frequencies must first be entered into the Preset Memory as follows: 1 . Tune to the station to be memorized by using Automatic Seek or Manual Tuning. 2. Press the "memory" switch. It will illuminate in green for 10 seconds. During this time, the AM or FM broadcast frequency that is being received can be entered into one of the 16 memory presets. To enter the broadcast frequency into a preset numbered 1-8, press the corresponding PRESET button while the "memory" button is illuminated. To enter into a preset numbered 9-16, press the "shift" button (it wil l illuminate) and then the corresponding PRESET button. 3. To cancel a memorized station and memorize a new station at that number, tune to the frequency of the new station and follow step 2 above. The old station is automatically cleared, and the new station is memorized. NOTE: Since this unit is provided with a memory backup circuit, the memory contents will remain stored for about one week when power cord is unplugged from an AC outlet. If the memory contents are cleared (erased), the presetting procedure must be performed again. When the "memory" switch is pressed, the switch illuminates in green for about 10 seconds. The memory function wil l only work while the "memory" switch is illuminated. Last Station Memory Function This function "remembers" the frequency last received before changing bands (FM/AM). ► When changing the band from FM to AM and again to FM, the last received FM station will be tuned in. This function also "remembers" the frequency of the station last received. ►When the power is turned on, the frequency of the station last received is displayed by the STATION DISPLAY, regardless of whether the station is a preset one or not. 5
