This manual provides tedmical informa-
tion necessary for servicing
the V XR -5000 FM
Land Mobile Repeater. A
reprint of the CE -8
channel-programming software ffic.nual is
also
included for easy reference.
Servicing this
equipment requires exper-
tise
in handling surface-mount chip compo-
nents.
Attempts by non-qualified persons to
service this
equipment may result in p'2rma-
nent damage not covered by the warranty,
and may be illegal in some countries.
Two PCB
layout diagrams are provided for
each double-sided circuit board in th2 re-
peater. Each side of the board is referred to by
Instruction Manu al
the type of the majority of components in-
stalled on that side ("leaded" or /I chip-
only"). In m ost cases one side has only chip
components,
and the other has either a mix-
ture of both chip and leaded components
(trimmers, coils, electrolytic capacitors, ~ Cs,
etc.), or leaded components only.
While
we believe the teclmical information
in this manual to be correct, Yaesu Musen
assumes no liability for damage that may oc-
cur as a resultof typographical or other errors
that may be present. Your cooperation in
pointing out any inconsistencies in the tech-
nical
information would be appreciated.

1. TX ANT
This N-type coaxial jack provides the
transmitter output signal for connection to
the
transmitting antenna, or TX jack on the
duplexer, if used. Impedance requirement
is 50Q.
2. RX ANT
This N-type coaxial jack accepts the re-
ceiver
input signal from the receiving an-
tenna or RX jack on the duplexer, if used.
Impedance requirement is 50Q.
3. AC
This receptacle accepts the AC power cord,
which should be connected to the AC
Mains supply or wall outlet. The AC line
voltage
must match that for which the re-
peater is wired.
4. BA TT terminal posts
The terminal posts accept 12-15-V DC for
operating the repeater from a battery or
other DC source. When operating from AC
mains, a small trickle current is present at
these terminals to maintain battery charge.
A
battery rated for 12 volts, 55 Ah (mini-
mum) is recommended for short-term
emergency /backup operation .

control and provides TX & RX audio, TX
keying and squelch status output. Imped-
ance is 600Q.
6. ACC
This DB-25 connector provides a data in-
terface
between the microprocessor in the

operation
while performing servicing and alignment. The repeater cabinet cover must be
removed to view these.

Programming Sofware Instructions chapter for details).

VXR-5000
Installation
Repeater operation without a duplexer re-
quires
that two antennas be inslalled, one for
receiving and one for transmitting, so that the
receiving antenna does not absorb energy
from the transmitting antenna. ~here are a
number of ways to do this, depending on the
TX/RX frequency separation, and on the lo-
cation
available for antenna mounting. If a
duplexer is used, a single antenna suffices for
both transmitting and receiving. If using a
reduced-size duplexer, a six-c avit y model
(minimum) is recommended.
Regardless of the above choice, it is of
paramount importance that the antenna(s) be
mounted as high as possible, and in the clear
as possible,
preferably within line-of-sight to
all
repeater users. ?urthermore, losses in the
feedline(s) must be minimized, so the
feedline(s) should be high quality, and as
short as possible. :aa long feedline is neces-
sary, use coaxial hard line cable to reduce
losses.
Repeater antennas should have an im ped-
ance of 50
ohms at the operating frequency.
When separate receive and transmit antennas
are used, high-Q narrow-band types may
serve to minimize interaction . H owe ve r,
when a single antenna is used with a du-
plexer, it should be a low- Q wide-band typ2.
NEVER TRANSMIT WITHOUT HAV-
ING A TRANSMIT ANTENNA CON-
NECTED TO THE REPEATER.
AC Pow er S upply Voltage Selection
Each repeater is wired for a particular AC
mains voltage between 100 and 234 VA C.
This should be indicated by a label ne ar the
AC jack
on the rear panel. If no label is pre-
sent, or if the AC voltage on the label is differ-
ent from the local AC line, check the wir in g to
the
power transformer inside the rep eater,
and change the connections (and label) if nec-
essary, as
shown on the following page .
Changing the transformer wiring also re-
quires changing the fuse in the power supply
if the voltage is changed from below 117-V
AC to
above 200 VAe, or vice-versa. Use a
Instruction Manu al
5-amp fuse for for 117 VAC or less, or a 3-amp
fuse for 200 VAC or more.
Operation
DC Power Supply Backup
For uninterrupted operation during
power failures, a 12-volt re chargeable type
battery (55-Ah or more recommended) may
be connected to the DC terminal posts on the
rear panel.
While the repeater is operating
from the AC source, a slight charging current
will maintain ba ttery charge. In the even of
AC
power outage, the automatic power con-
trol circuit will
automatically switch the re-
peater to the backup battery, and operation
will not be interrupted.
After prolonged operation from the bat-
tery, it
should be disconnected from the re-
peater and recharged separately before
re-connecting, as the trickle charge is not suf-
ficient for recharging a completely dis-
charged battery. Never reapp ly AC power to
the repeater with a dischar ge d b attery COF-
ne cted, as the DC s ta rtup currentcan damage
the repeater and
batte ry. While operating
from a battery or DC supply, the repeater
requires approximately 7 amperes at 12 volts
during transmit.
Equipment Loc ation
While the operating temperature range of
the repeater is quite broad, the best location is
still
one in which the air temperature does not
approach the extremes or change rapidly.
M
ake sure to allow for free air circulation
around the heatsink on the rear apron at all
times.
In warm climates, the repeater should
not be sealed in a small closed room.
Protect the repeater from wind and rain,
and extremes in temperature or humidity
that may shorten the useful life of the equip-
ment. Try to locate the repeater in an environ-
ment that is also comfortable for service
personnel, if possible.

Changing PowerTransformer AC
Mains Wiring
Before attempting this wiring change, re-
move the AC
power cord from the rear panel
jack.
o Remove the four screws affixing the top
cover
of the repeater, and remove the
cover.
o Note the location of the AC fuse, and the
three screws affixing the clear protective
plastic sheet to the repeater (one screw
near the fuse block,
and two on the PA
Unit).
o Remove the four screws and the plastic
sheet.
o Referring to the diagrambelow, determine
the correct transformer
primary jumper
wiring for the AC Mains voltage used in
your area.
o Next, using a medium power (approx. 30-
watt) soldering iron, rewire the jumpers
according to the diagram.
o If necessary, replace the AC fuse according
to theAC Mains voltage range:
100-117-V AC: SA
200-234-VAC: 3A
o Replace the clear protective sheet and
cover, this completes the wiring change.

Important!
If you change the AC
voltage range,
you must
also change the rear-panel
ACjitse. Do not replace
with a slow-blow type
fuse. Also makesure the
voltage marking
on the
rear-panellabelmatches
the
new voltage setting.

AC Mains Voltage Selection
Caution!
To avoid blowing the rear-panel AC fuse,
wait at least 30 seconds after un-plugging
the repeater AC power cord before plugging
it in again. This allows the DC power supply
capacitor-bank residual voltage to bleed
down, and prevent a high start-up current
when power is reapplied.
