Functional Description
Operation of each key is as follows while preset memories are being scanned:
Key
Operation
G
If released within 2 seconds
Preset memory scanning is stopped, and frequency at which key was
pressed is held.
G
If held down for 2 seconds or more
Preset memory scanning is stopped, and auto store memory operation is
started.
Stop preset memory scanning.
Call contents of preset memory corresponding to pressed key.
However, nothing can be written to preset memory.
Stop preset memory scanning.
Operation of pressed key is started from frequency at which key was pressed.
Stops preset memory scanning and selects band.
Continue preset memory scanning.
Operation of pressed key is performed.
Analog keys other than above are invalid.
G
Auto store memory
Searches broadcasting stations in DX mode in range from lower limit (minimum frequency) to
upper limit (maximum frequency) of currently received band, writes preset number of stations
starting from one with highest signal meter level, and then sorts stations in order of frequency.
In this case, if RDS broadcasting is received in FM band, the PI code of that station is also recorded
at the same time.
If stations having same PI codes are found, only station with highest signal meter level is written.
After operation, M1 is received. If no station is found, frequency at which operation was started
is resumed.
(a) If stations have been written to all the keys M1 through M5 and then another station is found
If signal meter level of that station is lower than signal meter level of station written to M5,
selection operation continues. If signal meter level is higher, that station is written to M5,
stations written to M1 to M5 are sorted again starting from highest signal meter level, and then
selection operation continues.
If stations with same signal meter level are found, it is assumed that signal meter level of
station found first is higher.
(b) If number of stations falls short of number of preset stations
Stations found so far are sequentially written to preset memory starting from M1, and found
stations are sorted in order of frequency.
Contents of remaining preset memory before auto store memory operation was performed
are preserved.
