Operation
FREQUENCY NAVIGATION
The
VX-5R
will initially be operating in the "VFO" mode, as just described. This is a
channelized system which allows free tuning throughout the currently-selected operating
band . You can confirm that you are in the VFO mode by looking in the upper-left-hand
corner of the display; if you see "Va" (which stands for "VFO-A") and/or "Vb" (VFO-B)
along the left edge of the LCD, then you are in the VFO mode .
Three basic frequency navigation methods are available on the
VX-5R :
1 . Tuning Dial
Rotation of the
DIAL
allows tuning in the pre-programmed steps established for the cur-
rent operating band . Clockwise rotation of the
DIAL
causes the
VX-5R
to be tuned toward
a higher frequency, while counter-clockwise rotation will lower the operating frequency.
If you press the [F[W] key momentarily, then rotate the
DIAL,
frequency steps of 1 MHz
will be selected . This feature is extremely useful for making rapid frequency excursions
over the wide tuning range of the
VX-5R .
2. Direct Keypad Frequency Entry
The desired operating frequency may be entered directly from the keypad.
The operating mode will automatically be set once the new frequency is entered via the
keypad .
To enter a frequency from the keypad, just press the numbered digits on the keypad in the
proper sequence . There is no "decimal point" key on the
VX-5R,
so if the frequency is
below 100 MHz (e .g . 15 .150 MHz), any required leading zeroes must be entered.

From the VFO mode, press and hold in the
[VFO(DW)SCI
key for one second .
The
VX-5R
will begin scanning toward a higher frequency, and will stop when it receives
a signal strong enough to break through the Squelch threshold . The
VX-5R
will then hold
on that frequency according to the setting of the "RESUME" mode (Menu #12) . See page
63 for details.
If you wish to reverse the direction of the scan (i .e . toward a lower frequency, instead of a
higher frequency), just rotate the
DIAL
one click in the counter-clockwise direction while
the
VX-5R
is scanning . The scanning direction will be reversed . To revert to scanning
toward a higher frequency once more, rotate the
DIAL
one click clockwise .

TRANSMISSION
AM BROADCAST
RECEPTION
Operation
Once you have
set up an appropriate
frequency inside one of the three
Amateur bands on
which the
VX-5R
can transmit (50 MHz,
144 MHz or 430 MHz), you're
ready to transmit .
These are the
most basic steps ; more
advanced aspects of transmitter
operation will be
discussed later .
(1) To transmit, press the
PTT switch, and speak
into the front panel microphone
(located
in the upper
right-hand corner of the speaker
grille) in a normal voice level
. The "TX"
LED on top of the
radio will glow Red during
transmission .
© To return to the receive
mode, release the PTT switch
.
During transmission, the
relative power level will be
indicated on the LCD. Full
power
(5 Watts) is indicated by eight
arrows below the frequency
display. The three "Low
Power" levels (L1, L2,
and L3) are indicated by
two, four, or six arrows,
respectively .
Additionally, the "L" icon
will appear at the bottom of
the display, followed by
one,
two, or three bars .
If you're just talking to
friends in the immediate
area, you'll get much longer
a
buttery life by switching to
Low Power operation. T o _
do this, just press the
[TX PO(LOCK)]
key so that the "L" icon
appears at the bottom of the
dis-
play. And don't forget,
always have an antenna
connected when you transmit
.
Transmission is not possible
on any operating bands
outer than the 50 MHz, 144
MHz,
and 430 MHz bands .
The
VX-5R
includes provision for reception
of AM broadcasts, either
on the standard
medium-wave (MW) broadcast
band, or on the
(1)
shortwave bands up to 16 MHz
.
1~ Press the
[VFO(DW)SC]
key repetitively until you
see a frequency in the
frequency
range desired. The MW coverage
is 0.5 MHz to 1 .8 MHz,
while the shortwave broad-
cast coverage is 1 .8 MHz
to 16 MHz. In either case,
the operating mode (displayed
on
the right edge of the LCD)
should be shown as being
"AM ."
~2
Be sure that the
VX-5R
is set to the VFO mode
(either "Va" or" Vb" will be
visible at
the left side of the display) .
(3
Rotate the
DIAL
to tune across the broadcast
band .
® You may also use the keypad
to enter frequencies directly
. This method will be
quicker
for changing from the 49-meter
broadcast band to the 31-meter
band, for example .
If the operating mode
is not correct, you may
need to adjust the setting of
Menu #36 (RX MODE).
