VXR-5000
Alignment
The
VXR-5000
has been factory aligned for
. the specified performance across the entire
operating
frequency
range.
Realignment
should not
be
necessary except
in
the event of
a component failure. All component replace-
ment
and
service should only
be
performed
by
an
authorized
Yaesu
service
repre-
sentative,
or
the

policy
may
be
voided.

Before alignment, connect the repeater and
PC to the VPL-l connection cable as de-
scribed
in
the Channel Programming Chap-
ter,
and
download the EEPROM
data
from
the transceiver to the computer. Then store
this data
in
a file so
that
it
can
be
uploaded
when
alignment is finished.
