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
reusable,
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 MATERIAL.
d.
Use
heavy
duty
shipping tape
to
secure
the
outside
of
the carton.
e.
Use
large F
RAG
I
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
The
FMM-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
F).
Mount 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. Attach a three wire,
grounded line cord
to
TB
1 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 TB2. 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
order
to
comply with FCC regulations
on remote metering. A remote peak modulation lamp may
be connected
to
terminals 9 and 10. CAUTION:
DO
NOT
SHORT TERMINAL 9
TO
GROUND. The remote meters
and lamp are contained
in
the
MP-1 Remote Meter Panel.
