Notice to the user:
One or more of the following statements
may be applicable to this equipment.
FCC WARNING
This equipment generates or uses radio
frequency energy. Changes or
modifications to this equipment may

equipment if an unauthorized change or
modification is made.
‘Information
to
the
І
digital
device
user
|
required
by
the
FCC:
This equipment has been tested and
found to comply with the limits for a
Class B digital device, pursuant to Part
115 of the FCC Rules. These limits are
designed to provide reasonable
protection against harmful interference in
а residential installation. This equipment
generates, uses and can generate radio
frequency energy and, if not installed and
| used in accordance with the instructions,
may cause harmful interference to radio
| communications. However, there is no
| guarantee that the interference will not
occur in a particular installation. If this
equipment does cause harmful
interference to radio or television
reception, which can be determined by
| turning the equipment off and on, the
user is encouraged to try to correct the
interference by one or more of the
following measures:
-- Reorient or relocate the receiving
antenna.
-- Increase the separation between

3-1. INSTALLATION
3-1-1. Fixed Station
B Front Bail
By
extending
the
front
bail,
the
front
panel
can
be
elevated for operating convenience.
|
CAUTION
|
Do
not
carry
the
transceiver
by
holding
the
bail.
Grasp
the
handle
on
the
right
side
to
carry
the
transceiver.
3-1-2. Mobile Installations
Secure
the

with
the
optional
mounting
bracket.
For
the
installation
instructions,
see
the
MB-430
Instruction
Manual.
3-2, CONNECTION

more
than
20.5

power.
Use
the
PS-53
power
supply
for

operation.
CAUTION
1.
Before
connecting
the
power
supply,
switch
the
transceiver
and
the
DC
power
supply
off.
2.
Do
not
plug
the

Caution
Protect

a
LIGHTNING
|
ARRESTER.
The
type
of
antenna
that
is
used
will
greatly
affect
the
performance
of
the
transceiver.
Use
a
properly
adjusted
antenna,
of
good
quality,
to
enable
your
transceiver
to
perform
at
its
best.
The
antenna
input
impedance
is
50
ohms.
Use
50-ohm
coaxial
cable
such
as
5D-2V
or
RG-213/U
(RG-8A/U)
for
this
connection.
If
the
antenna
is
far
from
the
transceiver
the
use
of
low
loss
coaxial
cable,
such
as
5D-2V
or
RG-213/U
(RG-8A/U)
are
recommended.
Match
the
impedance
of
the
coaxial
cable
and
that
of
the
antenna
so
that
the
SWR
is
less
than
1.5
to
1.
The
protection
circuit
in
the
transceiver
will
activate
if
the
SWR
is
particularly
poor
(greater
than
3
to
1).
High
SWR
values
will
cause
the
transmitter
output
to
drop,
and

1.
A

Making
a

is
important
for
preventing

(3) External speaker
The
Τ5-4505/6909
includes
a
built-in
speaker.
If
you
would
like
to
use
an
external

such
as
the
SP-23,
it
may
be
connected
to
the

(1) Headphones
Any low-impedance (4-16 ohms) headphone may be
used with the transceiver. Connect the headphones
to the front panel PHONES jack. (diameter 6.0 mm).
The optional HS-5 or HS-6 headphones are best
suited for use with the transceiver. Stereo type
headphones can also be used.
(2) Microphones
Any microphone with an impedance to 6000 may be
used with this transceiver. The KENWOOD
microphones MC-43S (handheld), MC-60A, MC-80,
MC-85 (table-top type) are recommended.

Install in the safest and most accessible
location.
A. Battery Connections
Connect the power cable directly to the battery
terminals.Use of the cigarette lighter socket will lead
to poor connection, and will result in poor
performance. Pay close attention to the polarity of
| 1. Before installing the power cable, be sure to
. remove the negative lead from the battery for
safety.
2. After installation and wiring, be sure to double
check for correct installation before
reconnecting the negative lead to the battery
terminal.
3. If the fuse opens, be sure to check that each
conductor has not been damaged by short
circuiting, etc. Then replace with a new fuse of
the same rating.
‚4. After completing the wiring, wrap the fuse holder |
with heat resistant tape to protect against heat
and moisture.

B. Ignition Noise
This transceiver has been designed to suppress
ignition noise; however, if excessive noise is
present, it may be necessary to use Suppressor
spark plugs (with resistors).

Grounding is very important when using a whip
antenna. If the grounding is poor, a good SWR value
will not be obtained.

NB2:

47, RIT/XIT control
RIT (Receiver incremental Tuning)
The RIT control shifts the receiver frequency
without changing the transmit frequency.
When the RIT switch is ON, the RIT indicator will
light, and the receive frequency can be adjusted
by using the RIT control.
| Note |
| When the RIT is ON the transmit frequency may ᾿
` be different from the receive frequency. For
normal operation leave the RIT switch OFF. It
should be used only when necessary.
The scan speed can be changed during scanning
with the RIT control.
XIT (Transmitter Incremental Tuning)
XIT is very similar to RIT. XIT is only active in the
transmit mode. By using the XIT function it is
possible to offset the transmit frequency without
the normal loss of receiver audio that is
experienced when using the SPLIT function.
When RIT/XIT is off, the RIT/XIT display dose not
light.
The RIT/XIT step size is either 10 Hz or 20 Hz.
Please refer to Section 4-11-15 for information on
how to select the desired step size.
48 IF SHIFT control
Interference can be eliminated and the receive
audio quality can be adjusted.
Note |
| This control is disabled during FM and AM |
operation. |
49 AF gain control
Turn the knob to increase or decrease the
volume.
Clockwise rotation increases the volume and
counterclockwise rotation decreases the volume.
| Note |
! The output level of the "Beep", "Sidetone"
| and VS-2 are not affected by adjusting of the
| AF gain control.
5) RF gain control
This contro! adjusts the gain of the receiver
high-frequency amplifier section.
For normal receiver performance, and maximum gain,
this control should be all the way to the right. If you
are having trouble copying the desired signal make a
note of the stations peak S-meter reading. Then,
adjust the RF gain control left, so that the meter is
stationary at this level. Now, all signals that were less
than the desired signal will be attenuated, such as
static noise, etc., making reception easier.
If the incoming signal pegs the S-meter you can also
reduce the receiver gain by moving the RF gain
control to the left. The S-meter will always advance
up-scale as the RF gain control is moved, to indicate
that the gain has been reduced.
Simultaneous use of the RF gain control and AGC
key.
If a strong signal (such as a local station) appears in
the vicinity of the intended receive signal, the S-meter
may show unusual deflection due to the AGC voltage
developed from the strong disturbing signal. If this
occurs, move the RF gain control to the left so the
meter pointer remains at about the original deflection
peak and select FAST AGC.
This will reduce the unwanted AGC voltage and
permit clear reception. _
Note
| Turn the control fully clockwise in the FM mode.
