NOTE:
The IC-735 transmits in the ranges shown
in the table, however it is the operator's
responsibility to follow the pertinent
government radio regulations.
6 - 2 BASIC OPERATION
The following instructions are for using the IC-735 in any mode.
Please read and understand them carefully before turning ON your
transceiver.
After setting each control and switch as described in 6 - 1, push the
POWER SWITCH IN. The meter and the frequency display lamp
illuminate and a frequency, mode, VFO, memory channel number,
etc. appear on the LCD.
6 - 2 - 1 FREQUENCY SELECTION
The IC-735 transmitter covers all HF Ham bands while other fre-
quencies are muted. In addition, the receiver covers all frequencies
from 0.1 to 30MHz continuously.
Rotate the TUNING CONTROL clockwise to increase the frequency,
and counterclockwise to decrease the frequency in 10Hz steps when
no step select buttons are pushed IN.
(1) kHz SWITCH
Push this button and rotate the TUNING CONTROL to change fre-
quency in 1kHz steps. The 100Hz digit automatically clears to "0"
when the switch is pushed.
(2) MHz SWITCH
Push this button and rotate the TUNING CONTROL to change fre-
quency in 1MHz steps. The 100kHz, 10kHz, 1kHz and 100Hz
digits do not change during this operation. The MHz SWITCH has
priority over the kHz SWITCH.
(3)
HAM SWITCH
The transceiver functions on the bands which include all HF Ham
bands from 1.8MHz to 28MHz inclusive. Push this button and
rotate the TUNING CONTROL to select each HAM band in a
continuous cycle as shown below.
1.8MHz 3.5MHz -4- 7MHz —> 10MHz - ÷14MHz
I
29MHz <— 28MHz 4- 24.5M H z <— 21MHz <— 18MHz <
When changing from one Amateur band to another with the HAM
SWITCH pushed, in all cases except 1.8MHz, the VFO automatically
rests at the frequency on the adjacent Amateur band which is in the
same relative position with respect to the newly selected band as was
the previously used frequency with respect to the previous band.
For example, beginning from 3.6MHz and rotating the TUNING
CONTROL clockwise with the HAM SWITCH pushed selects 7.1,
10.1, 14.1, 18.1, 21.1, 24.6, 28.6, and 29.6MHz, consecutively.
This feature permits very rapid frequency shifts to other bands so
that contacts on the same mode may be completed with almost no
adjustment or tuning of the transceiver.
When changing to or from the 1.8MHz band, the 100kHz, 10kHz,
1kHz, and 100Hz digits selected on the adjacent band, that is 3.5 or
29MHz, do not change.
Also, with the HAM SWITCH pushed, the USB mode is automati-
cally selected on the 10MHz band and above, and the LSB mode is
automatically selected on the 7MHz band and below.
The HAM button has priority over both the kHz and MHz buttons.
