SECTION 2
INSTALLATION
2- 1
INITIAL
INSPECTION
Check
the
shipping
carton
for
external damage. If
the
carton exhibits evidence
of
abuse in handling [holes,
broken corners, etc.] , ask
the
carrier's agent
to
be present
when
the
unit
is unpacked. Carefully unpack
the
unit
to
avoid damaging the
equipment
through use
of
careless
procedures. Inspect all
equipment
for
physical damage
immediately
after
unpacking. Bent
or
broken parts,
dents
and scratches should be
noted.
If damage
is
found, refer
to
Paragraph 2- 2 for
the
recommended claim procedure.
Keep all packing material
for
proof
of
damage claim or for
possible future use.
2-2
CLAIMS
If
the
unit
has
been damaged, notify
the
carrier
immediately. File a claim with
the
carrier
or
transportation
company and advise Belar
of
such action
to
arrange
the
repair
or
replacement
of
the
unit
without
waiting
for
a
claim
to
be
settled with
the
carrier.
2-3
REPACKING FOR SHIPMENT
If
the
unit
is
to
be
returned
to
Belar,
attach
a tag
to
it
showing owner and owner's address. A description
of
the
service required should be included
on
the
tag. The original
shipping carton and packaging materials should
be
used for
reshipment. If
they
are
not
available or reusabl
e,
the
unit
should be repackaged in
the
following manner:
a.
Use
a double-walled
carton
with a minimum
test
strength
of
275
pounds.
b.
Use
heavy paper
or
sheets
of
cardboard
to
protect
all
surfaces.
c.
Use
at
least 4 inches
of
tightly packed, industry
approved, shock absorbing material such as
extra
firm
polyurethane
foam
or
rubberized hair. NEWSPAPER IS
NOT SUFFICIENT FOR CUSHIONING
MA
TE
RIAL.
d.
Use
heavy
duty
shipping
tape
to
secure
the
outside
of
the
carton.
e.
Use
large FRAGI
LE
labels
on
each surface.
f. Return
the
unit, freight prepaid, via air freight. Be sure
to
insure
the
unit
for full value.

PREPARATION FOR USE
T
he
F
MM
- 1 Frequency and Modulation Monitor
is
designed
to
be
mounted in a standard 19-inch rack mount.
When mounted in a rack, a slight air space should be
provided above and below
the
unit
as
the
heat generated
by
the
crystal oven should be dissipated. When
the
monitor
is
mounted above high
heat
generation equipment such as
vacuum-
tube
power supplies, consideration should be given
to
cooling requirements which allow a free movement of
cooler air through and around
the
FMM
- 1. In
no
instance
should
the
ambient chassis temperature be allowed
to
rise
above
50
degrees C
(122
degrees
Fl.
M
ount
the
FMM
- 1
to
the
rack
mount
using
four
No.
10
screws and four No.
10
countersunk finishing washers.
The Model
FMM
- 1 requires a
105
to
125 VAC single
phase,
50
to
60
Hz
power source. Consult Belar for
operation with
other
power sources.
Attac
h a three wire,
grounded line cord
to
TB1 with
the
ground wire
to
terminal
2 and the AC line wires
to
terminals 1 and 3.
Connect a
50
ohm
coaxial cable [RG-58) between
the
monitor probe
on
the
transmitter [or RF amplifier) and
the
RF
input
connector
J7,
at
the
rear of
the
main chassis.
CAUTION:
DO
NOT
APPLY
MORE
THAN
10
VOLTS
RF
TO
THE
MONITOR
OR
THE
RF
INPUT
LEVEL
CONTROL
MAY
BE
DAMAGED
.
If desired, connect external aural monitoring amplifier
to
terminals 1 and 2
on
TB
2. Note
that
this
is
an unbalanced
600
ohm
output
with terminal 1 grounded. A
remote
center
frequency deviation meter
and
remote modulation
meter may be connected
to
terminals
7,
8 and 5, 6
respectively,
if
desired. Observe
the
proper polarities
[terminals 6
and
7 are positive) and
note
that
the
external
loop resistance
not
including meters must
be
5000
ohms.
These meters must
be
obtained from Belar Electronics
laboratory,
Inc. in ord
er
to
comp
ly with FCC regulations
on
remote
metering. A remote peak modulation lamp may
be
connected
to
te
rminals 9 and 10. CAUTION:
DO
NOT
SHOAT TERMINAL 9 TO GROUND.
The
remote meters
and lamp are contained in
the
MP
- 1 Remote Meter Panel.
