[. . . ] There is the possibility that a fire might be caused by making such a connection. Be sure to check the power source carefully, especially on a ship or other place where DC is used. , , *' Be sure to place the unit on a flat, level surface Never attempt to repair or reconstruct this unit If the surface is inclined, a malfunction may result. A serious electric shock might occur if this unit is repaired, disassembled or reconstructed by unauthorized persons, or if the internal parts are accidentally touched. · · Grasp the plug when disconnecting the power supply cord 1. A dangerous electric shock may result if the plug is touched by wet hands. [. . . ] Note, however, that the power plug should be left connected to the AC outlet. [6] Reverse button (reverse) This button is used to reverse the equalization curve shown in the display. [7] Display mode-select buttons (display mode) These buttons are used to select the equalization-level display mode and any of the three types of spectrum display mode described below. · Equalization-level display mode EQ level: Select this mode when you want to display the equalization level. Equalizer level-control buttons (equalizer level control) These buttons are used for adjustment of the equalization level of the left channel and right channel simultaneously. Upper row: These buttons are used to increase the level of each sound range (frequency range). Lower row: These buttons are used to reduce the level of each sound range (frequency range). · Spectrum display modes (spectrum analyzer) bar: dot: peak hold: Select this display. Select this be held in mode when you want a bar-type mode when you want a dot-type mode when you want the peak to the display. Memory mode-select button (memo mode) This button is used to select the equalization memory mode to be used. manual: Select this mode to program a desired curve to the unit's memory or to retrieve a curve that you have programmed. fixed: Select this mode to retrieve a curve that was originally pre-programmed to the unit's memory. Preset-memory buttons ([Tj-H) These buttons are used to program an equalization curve into the memory, or to retrieve a curve originally programmed into the unit's memory. Recording mode selector (EQ rec M. on) on: Set to this position to make a tape recording of a radio broadcast or a disc while controlling the frequency response. Set to this position to record without equalizer correction. Memory button (memory) This button is used to program the equalization curve into the memory. off: Equalization mode-select button (EQ on/off) This button is used to switch the equalization correction function "EQ on" and "off". Each time a button is pressed, the mode changes alternately to one or the other of the following modes. Note that the "EQ on" mode is automatically selected if a preset-memory button or an equalizer level-control button is pressed while this button is set to the "EQ off" mode. Input selector (A source . ·. tape) source: Set to this position to listen to the radio or a compact disc, etc. tape: Set to this position to listen to a tape deck connected to the back of this unit. -5- Front Panel Controls and Functions (continued) full range displays the combined level of all of the frequency ranges. Display section Equalization/Spectrum display The following equalization-level display and three types of spectrum display are possible. Note: If an equalization level-control or the memory-mode selector or a preset-memory button is pressed during any display other than the equalization-level display, the equalization-level display will be shown for about five seconds, after which the former display will return. · Equalization-level display The amount of correction is displayed by a series of lines (=) for each sound range (frequency range). \B\ Equalization-preset indicators (H]-®) The indicator corresponding to the pressed preset-memory button will illuminate. manual: Indicates an equalization curve that you programmed into the memory. fixed: Indicates one of the six equalization curves that were originally programmed into the memory. · Spectrum displays Bar-type display This display can be used to show the output strength for each sound range (frequency range), and to show the output strength of sound for all ranges (full range) by a bar-type display. lC\ Equalization-memory indicator (memory) This indicator illuminates when the memory button is pressed, thus indicating that an equalization curve can be programmed into the memory. \D\ Memory-mode indicators fixed: Indicates that one of the equalization curves that were originally programmed into the memory can be retrieved. Indicates that an equalization curve that you programmed into the memory can be retrieved. manual: Dot display Only the upper two parts of the bar display are shown, thus making the strength of the sound for each sound range even easier to see. [. . . ] Some simple checks or a minor adjustment on your part may eliminate the problem and restore proper operation. If you are in doubt about some of the check points, or if the remedies indicated in the chart do not solve the problem, refer to the directory of Authorized Service Centers (enclosed with this unit) to locate a convenient service center, or consult your Technics dealer for instructions. Problem No sound. Correction is not possible at playback (including recording. ) Probable cause(s) Incorrect connection. Suggested remedy Refer to page 4 and to the Operation Instructions of the amplifier. Set to "EQ on". The equalization mode-select button is set to "EQoff". [. . . ]
