Frequency And Band Selection; Indicators; Function Switch Operation - Kenwood TS-940S Instruction Manual

5-1. FREQUENCY AND BAND SELEC-
TION
• ®
Main display
Displays the operating frequency to the nearest 1 00 or 1 0
Hz depending upon the setting of the DISPLAY resolution
switch on the top control panel. RIT frequency is dis-
played up to
±
9.99 kHz.
The DISPLAY switch on the top panel allows you to select
the desired resolution. The analog scale display will nor-
mally indicate the relative band position through a 1 MHz
range, in 20 kHz steps. The step size and tuning range
may be changed to 2 kHz steps in a 1 00 kHz range thru
use of the SCALE switch.

Main Tuning control
Controls the dual digital VFO's operating in 1 0 Hz steps, at
a rate of 1 0 kHz per revolution for normal slow tuning.
When the control is rotated at a rate of over 5.5 to 6 revo-
lutions per second the tuning rate will increase in geom-
etric progression. The faster the knob is rotated the
greater the tuning step.
e
@ BAND/KEY switch
Selects one of the 10 HF amateur radio bands between
1.8 MHz and 29.7 MHz.
Note: Also used for direct keyboard entry of fre-
quency. See page 34.
e
@ 1 MHz step (UP/DOWN) switch
Increases (UP) or decreases (DOWN) the displayed fre-
quency in 1 MHz steps, throughout the entire frequency
range of the transceiver. Pressing and holding either
switch will cause the frequency to continuoslly step up or
down as long as the switch is held depressed.
5-2. INDICATORS
• @F. LOCK indicator
Lights up when the F. LOCK switch is pressed.
• @ VFO A indicator
Lights up during VFO A operation.
• @
VFO B indicator
Lights up during VFO B operation.
e
@MEMO (Memory) channel idicator
Shows memory channel operation and lights up when set-
ting the VFO/M switch
I@
to MEMO.
• ®
RIT indicator®
Lights up when turning on the RIT switch®.
• ®
XIT indicator®
Lights up when the XIT switch is ON.
• @)
ON AIR indicator (f)
Lights during transmit.
• @. (j]) ANT TUNE (Antenna Tuner) indicator (f)
Lights to show the automatic antenna tuner is in opera-
tion.
When lit, do not operate further until it goes off.
e
@
NOTCH indicator
Lights when the NOTCH switch is ON.
• @
DIM (Dimmer) switch
Selects the intensity of both the main digital display and
the meter illumination, bright or dim.
5-3. FUNCTION SWITCH OPERATION
These selects receive and transmit frequencies.
e
@ T -F SET switch
Depress the switch to "SPOT', or momentarily select the
transmit frequency when operating in the "SPLIT' mode.
Frequency "Spotting" is possible only in receive and is in-
effective during transmission.
•
~
A/8 switch
Selects the VFO A or VFO B.
In VFO A orB, mode, RIT and XIT can be set seperately.
e
@
SPLIT switch
For split frequency operations; A-R. B-T (A receive, B
transmit), or B-R, A-T.
When the switch is on, the SPLIT indicator lights.
• @I A= B switch
Used to equalize the frequency of the idle VFO with that of
the active VFO. RIT, XIT and mode are also equalized.
e@
F. LOCK switch
Used to lock the frequency of the VFO. In this state, the
frequency cannot be varied with the main tuning control or
band switches. However, RIT and XIT still function.
The F. LOCK indicator lights.
e
@ VOICE switch
When the optional VS-1 voice unit is installed the operat-
ing frequency will be announced whenever the VOICE
switch is pressed.
For a dial frequency of 14.200.00 the frequency will be an-
nounced as: "One", "four", "point", "two", "zero", "zero",
"zero", "zero".
Note: --------------------------------------
If the voice synthesizer (VS-1 installed) is not activated
even when the VOICE switch is operated, turn the POWER
switch OFF and turn it ON again to release the locked
state.
