In this case, a 3.125 kHz buzzer is output. - Keeping the key depressed for more than 0.5 second changes frequency upwards by one step every 100 ms. - At the band edge (changeover from maximum frequency to minimum frequency), there is a 500 ms wait. Up / Hour Tape mode - Key is inoperative. Clock setting mode - During clock 1 and 2 setting, hour indication changes upwards by one step with each push. Keeping the key depressed for more than 0.5 seconds causes a change by one step every 250 ms, until the key is released. Alarm setting mode - During alarm setting, hour indication changes upwards by one step with each push. Keeping the key depressed for more than 0.5 seconds causes a change by one step every 250 ms, until the key is released. Tuner mode - Frequency changes downwards by one step when a key is depressed for less than 0.5 second and released. In this case, a 3.125 kHz buzzer is output. - Keeping the key depressed for more than 0.5 second changes frequency downwards by one step every 100 ms. - At the band edge (changeover from minimum frequency to maximum frequency), there is a 500 ms wait. Tape mode Down / Min - Key is inoperative. Clock setting mode - During clock 1 and 2 setting, minute indication changes upwards by one step with each push. Keeping the key depressed for more than 0.5 seconds causes a change by one step every 150 ms, until the key is released. Alarm setting mode - During alarm setting, hour indication changes upwards by one step with each push. Keeping the key depressed for more than 0.5 seconds causes a change by one step every 150 ms, until the key is released. Tuner mode - Serve for preset station recall and store. - Pressing a key and releasing it within less than 2 seconds calls up the frequency stored in the corresponding preset number (1 -- 10). Memo 1 Memo 2 Memo 3 Memo 4 Memo 5 Keeping a key depressed for 2 seconds or more writes the currently received frequency to the corresponding preset number (1 -- 10). - For information on switching between presets 1 -- 5 and 6 -- 10, see the Memo+ key section. - When recall or store is confirmed, a 1.56 kHz beep corresponding to the preset number is output. Tape mode - Keys are inoperative. Power off mode - Keeping a key depressed for more than 500 seconds calls up the corresponding clock display for Memo1 or Memo2. No.6633-5/10 LC72348G-9970 Key Operation Description Tuner mode - Pressing this key and then one of the Memo1 -- Memo5 keys within 5 seconds causes the preset numbers 6 -- 10 to be called. Pressing one of the Memo1 -- Memo5 keys after 5 seconds have elapsed or after another key was pressed causes the preset numbers 1 -- 5 to be called. - At each push of the key, a 1.56 kHz beep is output for 50 ms. Tape mode - Key is inoperative. Power off mode - Serves for activating and terminating the clock/alarm setting mode. - Keeping the key depressed for at least 1 second causes the following mode change. Memo+ Clock display Alarm setting mode Clock setting mode - In alarm setting mode, the alarm time is placed in the setting area. During the setting procedure, the DOLBY mark flashes on the display, regardless of the alarm ON / OFF state. - Pressing the key again during alarm setting terminates the setting procedure and causes the set time to be placed in the setting area and serves for clock setting mode. The DOLBY display indication depends on the alarm ON / OFF state. - In clock setting mode, the time of the currently selected clock number is placed in the setting area. During the setting procedure, the colon of the time display stops flashing and stays constantly lit, but the clock count continues. - Pressing the key once more during clock setting cause the currently set time to be placed in the area for the currently selected clock number. By resetting the minute figures the seconds area is cleared to 00, count restart, and the colon of the time display starts flashing. - 12-hour notation; colon 24-hour notation; JAZZ, not colon Tuner mode / tape mode / power off mode - Alarm ON / OFF key When alarm is turned ON, DOLBY mark on display is shown. ALARM When alarm is turned OFF, DOLBY mark on display is out. - Alarm sound is output from BUZZER terminal as 3.125 kHz pulse for 5 minutes. Pressing this key again during alarm output stops the alarm sound. Last alarm time setting is retained. - Alarm sound is output in all modes. - Alarm sound is output to when the displayed time matches the alarm set time regardless of the clocks 1 and 2. - This key serves for power on / off control and band switching. The operation sequence is as follows. Power OFF (TAPE) -> AM band -> FM I band -> FM II band -> Power OFF (TAPE). Function - Keeping the key depressed for 2 seconds or more while AM band or FM I band is selected switches to Power OFF (TAPE). Releasing the key within less than 2 seconds switches to the next band. - Power OFF or TAPE is determined by the tape input port. - This key serves for toggling between FM mono and FM stereo. It is valid in the FM I and FM II bands. FM stereo <--> FM mono. - When FM stereo is set FM MN / ST When STEREO is ”High”, ”FM STEREO” flashes. When STEREO is ”Low”, ”FM STEREO” is lit. - When FM mono is set, ”Low” is output from the FM MN / ST port. - When no FM band is set, ”Low” is output from the FM MN / ST port. - This function is available in tuner mode except for the destination area East Europe. To perform switching, the two keys shown in the table below must be pressed together for 7 seconds or more. Initial destination area setting JP US EU Key World area switching ” Memo + ” + ” UP ” US JP -- ” Memo + ” + ” Down ” EU EU US ” UP ” + ” Down ” JP US EU - When switching is confirmed, and if a different area was selected, preset numbers 1 -- 10 in all bands will be set to the default values for the new area, and the lowest frequency in the currently selected band is received. - When switching is confirmed, the following indication is shown for 1 second in the 7-segment display area: Japan : JP USA : US Europe : EU - Selects whether clock function is enabled or not. CLOCK Sel (Diode switch) - During initialization, data are read and the setting is made as follows. OFF : Clock function enabled (12-hour notation; 2 time settings possible) ON : Clock function disabled - Selects whether alarm function is enabled or not. ALARM Sel (Diode switch) - During initialization, data are read and the setting is made as follows. If the clock is disabled, the alarm function is also not available.
