Momentary Keys
Function
Symbol
In the radio mode, these keys are used to call and write preset memory. In the tape mode,
these are used as tape function keys by initialize diode (ENTPK, KAMS, KNR, KMTL).
Radio mode
Preset memory call and write keys.
One key can memorize the FM1, FM2, FM3, VF, MW1, MW2, and LW bands independently
(max. 6 bands).
The following operations are performed according to the state of M2S of the initialize
diodes:
M2S
ME
Description
The device is placed into the 5 seconds preset memory write mode by pressing the
key during frequency display. When one of the keys
to
is pressed during this 5 seconds, the current receiving frequency is
written to the preset memory corresponding to the pressed key.
When the
key is held down, writing is not performed. During writing,
radio muting is not output.

When the same preset memory key is pressed while the current preset memory contents
are being received, the same operation is performed.
In the radio mode, when the device is in the memory unwritable state, when one of the
to
keys is pressed, the preset memory contents corre-
sponding to the pressed key can be called.

When the same preset memory key is pressed while the current preset memory contents
are being received, no operation is performed. However, if the clock is being displayed,
BEEP is output and the display switches to frequency display. Radio muting is not output.
