WARNING:
Connect

totlieECW-40.
Congratulations
on
your
purchase
of
an
Eventide
ECW-40
Satellite
ChrcmOTieter,
a
precise
time
base
fw
synchronizing
entire
systems.
Unlike
other
time
measurement
systems,
the
ECW-40
works
anywhere
on
earth,
anytime,
and
under
any
weather
conditions.
The
ECW-40
is
a
unique
product
that
can
provide
a
primary
source
of
traceable
and
reliable
time.
It
meets
the
critical
requirement
of
providing
legal
external
time
synchronization
for
public
safety,
transportation,
and
fi
nance
communication
systems,
and
can
assure
accurate
event
logging
and
billing
for
telephone
and
power
utilities.

sudi
as
the
Eventide
models
VR240
and
VR204,
and
the
Dictaphone
9800,
will
fi
nd
that
the
ECW-40
serves
as
an
extreme^
accurate
time
and
date
source,
providing
an
external
refisence
standard
to
eliminate
any
possible
drift
inherent
in
these
umts'
mtonal
clocks.
A
single
ECW-40
can
serve
as
a
master
reference
clodc
for
a
group
of
such
recmders.
The
ECW-
40's
extra-large
display
can
also
be
switched
to
show
the

of
an
audio

as
it
is

The

The

(GPS)
based
on

All

The
ECW-40
uses
the
most
modem
technology
available
It
has
a
built-in
GPS
receiver,
I
which
simultaneously
receives
time

to

with

A

devices,
such
as

omsoles,
ccmqiuter-aided

systems,
and

clocks.
When
100%

is
required,
two
ECW-40S
can
be
programmed
to
work
together.
Software
designates
one
as
the
master
and
the
other
as
the
backup.
If
the
master
detects
a
failure,
it
automatically
switches
to
the
backup's
output,
providing
full
redundancy.
If
you
have
purchased
a
second
ECW-40
f(»'
a
backup,
you
may
want
to

Both
window
and
outdoor
antennas
need
a
clear
view
of
the
sky
to
provide
reliable
reception.
Window
mounted
antennas
should
be
placed
with
the
sticker
facing
out
or
as
shown
in
the
antenna
mounting
kit
manual.
The
cable
(feedline)
should
run
fr
om
the
antenna
to
the
GPS
ANTENNA
connector
on
the
back
of
the
ECW-^O
(be
sure
to
connect
a
feedline
to
this
connector
before
applying
power
to
the

Ifyou
are
installing
a

(lightning)
suppressor,
connect
it
in

If
you
own
a
back-up
ECW-40,
you
can
install
a
separate
antenna
for

or
use
a
signal
"splitter"
to

anteima;
it's
also
ok^
to
nxMmt
separate
antennas

An
outdoor
roof
or
a
tower-mounted
antenna
should
be
placed
with
the
connector
side
facing
down,
toward
the
ground.
Follow
the
mounting
kit
instructions
on
mounting
the
antenna
to
the
roof
or
tower
for
best
results.
Connect
a
signal
amplifier
or
surge
suppressor
in
series
with
the
feedline,
at
the
