INSTALLATION
Introduction
Installation
of a
DECADE
FM
transmitter
includes
the
following
steps:
1)
receiving inspection;
2) mounting in
a rack or on a shelf; 3) connection
of the
AC
supply and
audio
source;
location, installation and connection
of the
antenna.
Receiving inspection
Check the transmitter
packaging
for any
damage that could
have
occured
in
the shiping.
lf
you
find
any
damage
on
the transmitter,
keep
the
packaging
for
claiming
purposes
with
the
freight company. Any
damage should be
noted
on the
receiving
slip at the time of delivery and
the
freight
company
advised
within
5 workable
days
following
the
delivery of damaged units.
Connections
After
installation
of the transmitter
in
a
rack
or on a
shelf,
plug
the
AC
cable
in
the
AC receptacle
on the back
panel,
and connect
to a
12O V,
60 Hz
grounded
AC
socket. As with
any
grounded
electric equipement,
it is not
recommended
to use
a
DECADE
transmitter
without
a
grounded
AC
socket, or removing
the
grouding
pin
on
the
cable,
since that
may
result in
shock
hazards for
the staff
in
contact with it.
Location
of
the transmitter and antenna
DECADE
transmitters
are designed
for indoor
or outdoor use in a dry
environment, in
temperatures
ranging
from
-20
to 60
'C.
In
order to
obtain optimum
performances,
it is
recommended
to
place
them
far from
any electromagnetic
noise source
(transformers,
motors,
etc.).
Antenna
should be
located
as close to
the
center of
the
hall
or coverage
area
as
possible,
and
at
a
sufficient
height
to
give
the transmitted
signal
a unobstructed
path
to every seat or receiving
point.
Concrete
walls
and
steel
beam
or sheets
greatly
attenuate
radio
waves, so avoid to
have
the
transmitted
signal
path
going
through
them, On the
other hand,
windows
are very
permeable
to
radio waves,
so avoid locating the antenna
near
them if
you
wish
to
restrain
the coverage
to the
interior of a building.
