7.5 Auto Store Memory
The auto store memory operation is started when the
PSCAN/ASM
key is held down for 2 seconds or more
in tuner mode with initial setting diode FUNC = 0, or when the
or more with FUNC = 1.
A mute timing diagram showing the auto store memory operation is given below.
M1
key is held down for 2 seconds
1 : Key ON chattering prevention
2 : Leading mute
3 : Division ratio setting
4 : PLL lock wait
5 : SD stabilization wait 1
6 : SD stabilization wait 2
7 : Trailing mute
8 : ASM end. Sorting is executed in the order of frequency, and preset memory M1 is called. If no
station is detected, the frequency before the key is pressed is retained. If a station is found after
stations have been written up to M5, it is compared with the SD level of the written preset, and
is sorted starting from the highest SD level.
