SCANNING OPERATION
The IC-551D provides various scanning operations. Read the following instructions carefully to
fully enjoy the IC-5b51D's many capabilities. |
MEMORY SCAN
This is to scan the three Memory Channels continuously. |
1. Program three desired frequencies in Memory Channels 1, 121, and ІЗ
2. 'Set the VFO Switch to the "MS" position. At this time, ra operatio or displayed frequency
is not changed.
3. Depress the MS/MW Switch, and the display frequency starts scanning the programmed :
frequencies in the Memory Channels 1, [2], [3], 1, [2], [3],
4. |f the SQUELCH is engaged, the scan stops when the squelch is opened and receives a signal.
To stop scanning without opening the squelch, depress the MS/MW Button. Depress it again |
to restart the scanning.
. PROGRAMMED SCAN "А"
This is to scan between two desired frequencies, which are programmed in Memory Channels
[2] and [3]. | |
1. Program the frequencies of the high and low edge of the desired scanning range іп Memory
Channels [2] and [3]. Regardless of which channel the higher frequency is programmed in, the
scan starts from the high edge of the range. |

2. Set the VFO Switch to "А". Depressing the MS/MW Button starts the scan from the high -
edge (50.8MHz) to the low edge. The scanning frequency increments depend on the MODE
Switch setting and the TS Button setting.
3. When the scanning frequency reaches the low edge (50.2MHz), it automatically returns to
the high edge (50.8MHz) and continues scanning down to provide endless scanning operation.
4. While the SQUELCH is engaged, the squelch opening when a signal is received will stop the
scanning automatically to lock onto the frequency. Depressing the MS/MW Button will
restart the scan from the frequency at which it stopped. If the RECEIVE indicator LED is
lit because the SQUELCH is not engaged, the scan does not stop at any signals.
5. To stop the scan operation, depress the MS/MW Button. Depressing the MS/MW Button
again restarts the scan from the high edge (50.8MHz) of the programmed range.

PROGRAMMED SCAN "В"
As with PROGRAMMED Scan "А", this is a scanning operation between two programmed fre-
quencies in Memory Channels [2] and ІЗІ, the basic difference being shown іп 3 below.
