than 1 second.
TC9307AF-010
c. When [FAST] key is kept pushed together with [UP]/[DOWN] key, the high speed continuous
tuning results. During the high speed continuous tuning, the continuous tuning up/down step
frequency normally changes as follows :
STEP FREQUENCY
BAND SCAN TIME NORMAL ACCELERATED
100kHz 200kHz
FM 100ms/STEP 50kHz 200kHz
9kHz 18kHz
MW 200ms/STEP 10kHz 20kHz
LW 200ms/STEP 1kHz 2kHz
SW 200ms/STEP 5kHz 100kHz
However, in SW band, if frequency below 0.1MHz is not zero when [UP]/[DOWN] key and
[FAST] key are pushed, after the up/down tuning as follows, the up/down tuning at 100kHz is
carried out.
In case of 16.555MHz
[UP] + [FAST]
16.555MHz-916.600MHz-916.700MHz--9
[DOWN] + [FAST]
16.555MHz-y16.500MHz-y16.400MHz---y
d. During the continuous tuning, any other key input is not accepted and even a broadcasting
station is detected, it is not stopped.
If the upper limit frequency is reached, it shifts toward the lower limit frequency and when the
lower limit frequency is reached, it shifts toward the upper limit frequency.
At this time, the system stops for 500ms as frequency.
