Momentary Key
Function
These keys increment or decrement the received frequency of the radio, or are auto seek up/down
keys.
They are valid in the radio mode.
Even in the radio mode, these keys can be also used to adjust the clock by pressing the DISP key
at the same time during clock display.
For how to adjust the clock, refer to the description of the DISP key.
The operation of these keys is as follows, depending on how long each key is held down.
Key Pressed for:
Operation
Less than 0.7
seconds
Each time the key is pressed, the received frequency is incremented
( MAN UP/SEEK UP key) or decremented ( MAN DWN/SEEK DWN key)
by 1 channel space.
0.7 seconds or
longer
If the key is held down for 0.7 seconds, an auto seek operation is started in
the up ( MAN UP/SEEK UP key) or down ( MAN DWN/SEEK DWN key)
direction.
The auto seek operation is performed as follows, depending on the on/off status of the local mode
when the operation is started.
Local Mode
Operation
On
The reception frequency is incremented or decremented by 1 channel
space in the local mode, starting from the frequency when the operation
was started, while detection of a station at each frequency is identified.
If the frequency is incremented/decremented to the original reception
frequency, the reception frequency in the DX mode is
incremented/decremented by 1 channel space while detection of a station
at each frequency is identified, until a station is detected.
If a station has been detected, the auto seek operation ends, and the
frequency at that time is received.
Off
The reception frequency when the operation is started is incremented or
decremented by 1 channel space in the DX mode while detection of a
station at each frequency is identified, until a station is detected.
If a station has been detected, the auto seek operation ends, and the
frequency at that time is received.
MAN UP/SEEK UP
MAN DWN/SEEK DWN
For how to identify detection of a station, refer to “3. RADIO FUNCTIONS”.
