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:
•
Use a double-walled carton with a test strength no less than 275 pounds.
•
Use heavy paper or sheets of cardboard to protect all surfaces.
•
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.
•
Use heavy-duty shipping tape to secure the outside to the carton.
•
Use large FRAGILE labels on each surface.
•
Return the unit, freight prepaid, via airfreight.
•
Be sure to insure the unit for full value.
NOTE: All text below that duplicates text appearing on the FMHD-1 display appears in a Courier font.

Installation
3.1 Operating Environment & AC Line Power
The FMHD-1 All-In-One FM Modulation Monitor is designed to be mounted in a standard
19-inch (48cm) rack with EIA standard spacing. Air space should be provided above and below the unit
to provide cooling. When mounted above heat-generating equipment, consideration should be given to the
requirement of the free movement of cooler air around and through the
FMHD-1 . In no instance should
the chassis temperature be allowed to rise above 113°F (45°C). Mount the FMHD-1 in the rack using the
four black 10-32 rack mounting screws provided.
Prior to serial number 450395,
the FMHD-1 was powered by an external switching
power supply module (supplied with the unit) that operates on line voltages in the range of 100 to 240VAC,
50 to 60 Hz. It provides outputs of +5 VDC, and ±12 VDC for the FMHD-1 chassis via a 48-inch (1.2m)
captive cable and a 5-pin DIN connector. The power supply module is connected to the AC line via an
IEC-320 three-conductor cable with a PH-386 grounded connector. When the power supply module is
connected between the FMHD-1 and an appropriate AC line source using an appropriate power cord, the
monitor is grounded. (To preserve the grounding when operating the unit from a non-standard two-contact
AC outlet, use a three-prong-to-two-prong adapter at the AC-line end and connect the green pigtail on the
adapter to a good electrical ground.)
Use the power supply module supplied with the FMHD-1. Substituting another power supply module may
result in damage to the FMHD-1, or at a minimum, a reduction in performance.
