Operation Description  
Tuner mode  
- Frequency changes upwards by one step with each push.  
- Keeping the key depressed for more than 0.5 seconds starts seek operation. During seek, frequency changes upwards by one step  
every 100 ms. This continues until seek ends, also when the key is released.  
- Seek ends if a valid tuning key (Up, Down, Memo1 - Memo5, FUNC) is pressed.  
- At the band edge (changeover from maximum frequency to minimum frequency), there is a 500 ms wait.  
- At each upward step, a 3.125 kHz beep signal is output for 50 ms.  
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 with each push.  
- Keeping the key depressed for more than 0.5 seconds starts seek operation. During seek, frequency changes downwards by one step  
every 100 ms. This continues until seek ends, also when the key is released.  
- Seek ends if a valid tuning key (Up, Down, Memo1 -- Memo5, FUNC) is pressed.  
- At the band edge (changeover from minimum frequency to maximum frequency), there is a 500 ms wait.  
- At each downward step, a 3.125 kHz beep signal is output for 50 ms.  
Down / Min Tape mode  
- 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).  
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.

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.

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.

When alarm is turned ON, DOLBY mark on display is shown.  
When alarm is turned OFF, DOLBY mark on display is out.  
ALARM  
- 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).  
- 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.  
Function  
- 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  
When STEREO is ”High”, ”FM STEREO” flashes.  
FM MN / ST  
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.

products or equipment. To verify symptoms and states that cannot be evaluated in an independent device,  
the customer should always evaluate and test devices mounted in the customer's products or equipment.  
SANYO Electric Co., Ltd. strives to supply high-quality high-reliability products. However, any and all  
semiconductor products fail with some probability. It is possible that these probabilistic failures could  
give rise to accidents or events that could endanger human lives, that could give rise to smoke or fire,  
or that could cause damage to other property. When designing equipment, adopt safety measures so  
that these kinds of accidents or events cannot occur. Such measures include but are not limited to protective  
circuits and error prevention circuits for safe design, redundant design, and structural design.
