MODE SELECT SWITCHES
() TUNING CONTROL
This is a push-lock switch which controls the input DC power to the
IC-735. When the PS-55 AC power supply is used, the switch also
acts as the AC power supply switch. Power is supplied to the
transceiver when the switch is pushed in and locked. Power to all
circuits is cut (except to the PA unit when using a DC power supply)
when the switch is pushed again and released.
This control varies the audio output level in the receive mode.
Clockwise rotation increases the level.
This control sets the squelch threshold level. To turn off the squelch
function, rotate this control completely counterclockwise. To set
the threshold level higher, rotate the control clockwise.
These switches select any one of four operating modes; either SSB,
CW, AM or FM. Each push of the SSB button alternately selects
USB and LSB. Additionally, the "correct" sideband (USB for
10MHz and above, LSB for 7MHz and below) is automatically
selected when the HAM switch is pushed. This is explained in
greater detail in item 8.
Rotate this control clockwise to increase, and counterclockwise to
decrease the frequency. The frequency changes in 10Hz steps in any
mode, although the number of steps per dial revolution auto-
matically increases when the control is rotated more rapidly. This
control is also used to select the operating band while the HAM
button is pushed.
© kHz TUNING RATE SWITCH This switch sets the tuning rate for 1kHz steps. See Section 6-2-1
for more information.
MHz and HAM buttons have priority over the kHz button.
0 MHz TUNING RATE SWITCH
This switch sets the tuning rate for 1MHz steps. See Section 6-2-1
for more information.
The HAM button has priority over the MHz button.
