Scanning Operation; Frequency Setting - Icom IC-R71A Instruction Manual

The contents of the channel will be cleared.
Pushing the FUNCTION KEY
first, then the MEMORY WRITE
button.
5-3 FREQUENCY SETTING BY KEY PAD
By pushing digit keys in order of the desired frequency
digits, the frequency display will be changed accordingly.
When the frequency display shows the desired frequency,
push the "ENT" key and the operating frequency of the
IC-R71 will be changed to the displayed one.
FOR EXAMPLE:
When desiring to set 21.234.5MHz, push digit keys as
follows;
AMADA
If you pushed a wrong digit key (before pushing the "ENT"
key), push the "CE" key, and the frequency display shows
the previous frequency (operating frequency). Now you
can set the desired frequency again.
When setting the desired frequency, push all digit keys in
order down to the 100Hz digit, then the "ENT" key,
except the desired frequency is exactly on a MHz (for
example; 14.000.0MHz).
FOR EXAMPLE:
When desiring to set 14.000.0MHz, push digit keys as
follows;
(14) LENT
When the desired frequency is lower than 1MHz, push "0"
key first, then digit keys of the desired one.
FOR EXAMPLE:
When desiring to set 828KHz (0.828.0MHz), push digit
keys as follows;
(oj(si(2|[8][o]
When the TUNING RATE SWITCH of the IC-R71 is turned
ON, the 100Hz digit will be ''0'', even if another figure has
been entered. So if you want to set a frequency that has a
100Hz digit other than ''0'', be sure to turn OFF the
TUNING RATE SWITCH.
5-4 SCANNING OPERATION
The IC-R71 provides various scanning operations. Please
read the following instructions carefully to fully enjoy the
IC-R71's many capabilities.
5-4-1 MEMORY SCAN
This is used to scan all programmed memory channels
continuously.
1. Program your desired frequencies into memory channels.
2. Select a memory channel programmed with a frequency.
(The scan cannot start from a blank channel.)
3. Depress the SCAN START/STOP button, and the fre-
quency starts scanning the programmed frequencies in
the memory channels from the highest channel to the
lowest. At this time, the scan skips blank channels, if any.
4. If the SQUELCH is engaged, the scan stops when the
squelch is opened and a signal is received. The scan
restarts after a specified delay time.
To stop scanning without opening the squelch, depress
the SCAN START/STOP button. Depress it again to
restart the scanning.
5-4-2 MODE SELECTIVE SCAN
In the memory scan mode, by pushing the MODE SELEC-
TIVE SCAN switch in, the scan scans only on channels
having the desired operating mode.
To be in this scan mode, first, select a channel that has your
desired mode, second, push the MODE SELECTIVE switch
in, then the SCAN START/STOP button.
When the set is scanning in the normal memory scan mode,
push the MODE SELECTIVE switch in at the moment that
your desired mode is displayed on the display.
5-4-3 PROGRAMMED SCAN
This is to scan between two desired frequencies, which are
memorized in the memory channels ''1" and ''2"'.
1. Memorize the frequencies of the high and low edges of
the desired scanning range into the memory channels 1
and 2. Regardless of which channel the higher frequency
is memorized in, the scan starts from the high edge of
the range.
For example, 14.200MHz is in the memory channel 1
and 14.300MHz in the channel 2.
2. Place the unit in the VFO MODE and select the opera-
tion mode the same as the channels 1 and 2, and either
VFO. Pushing the SCAN START/STOP button starts
the scan from the high edge (14.300MHz) to the low
edge (14.200MHz). The scanning frequency increments
depend on the TUNING RATE SELECT switch setting.
