Key Operation Description
Key
Operation Description
Tuner mode
- Frequency changes upwards 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.
- When the key is pressed and held down for more than 0.5 seconds, the frequency is incremented by one step every 100 ms until
the key is released. When the key is released, the system switches to seek mode.
- In the state where the key is held down continuously, the frequency increment operation continues in the "no station selected" state.
When the key is released, the system switches to seek mode, enters the "station selection state", and stops at the next frequency
where a station is present.
- When the system reaches the end of the band, it waits for 500 ms and then switches from the maximum frequency to the minimum
Up / Hour
frequency in the band.
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.
- When the key is pressed and held down for more than 0.5 seconds, the frequency is decremented by one step every 100 ms
until the key is released. When the key is released, the system switches to seek mode.
- In the state where the key is held down continuously, the frequency decrement operation continues in the "no station selected" state.
When the key is released, the system switches to seek mode, enters the "station selection state", and stops at the next frequency
where a station is present.
- When the system reaches the end of the band, it waits for 500 ms and then switches from the minimum frequency to the maximum
Down / Min
frequency in the band.
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 to 10).
Keeping a key depressed for 2 seconds or more writes the currently received frequency to the corresponding preset number (1 to 10).
- For information on switching between presets 1 to 5 and 6 to 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.
Memo 1
Memo 2
Memo 3
Memo 4
