NJRC strives to produce reliable and high quality microwave components.
NJRC's microwave components are intended for specific applications and
require proper maintenance and handling. To enhance the performance
and service of NJRC's microwave components, the devices, machinery or
equipment into which they are integrated should undergo preventative
maintenance and inspection at regularly scheduled intervals. Failure to
properly maintain equipment and machinery incorporating these products
can result in catastrophic system failures.
To ensure the highest levels of reliability, NJRC products must always be
properly handled. The introduction of external contaminants (e.g. dust, oil
or cosmetics) can result in failures of microwave components.
NJRC offers a variety of microwave components intended for particular
applications. It is important that you select the proper component for your
intended application. You may contact NJRC's sales office or sales
representatives, if you are uncertain about the products listed in the
catalog and the specification sheets.
Special care is required in designing devices, machinery or equipment,
which demand high levels of reliability. This is particularly important when
designing critical components or systems whose foreseeable failure can
result in situations that could adversely affect health or safety. In
designing such critical devices, equipment or machinery, careful
consideration should be given to, amongst other things, their safety
design, fail-safe design, back-up and redundancy systems, and diffusion
design.
The products listed in the catalog and specification sheets may not be
appropriate for use in certain equipment where reliability is critical or
where the products may be subjected to extreme conditions. You should
consult our sales office or sales representatives before using the products
in any of the following types of equipment.
* Aerospace Equipment
* Equipment Used in the Deep Sea
* Power Generator Control Equipment (nuclear, steam, hydraulic)
* Life Maintenance Medical Equipment
* Fire Alarm/Intruder Detector
* Vehicle Control Equipment (automobile, airplane, railroad, ship, etc.)
* Various Safety Equipment

6.2. Connecting Modem
The Unit is connected the modem.
Step 1:
Location of Coaxial Connector
The Unit receives the reference and the IF signal and is required to supply
+15 to +30 V DC power from the modem via coaxial cable.
When connecting the coaxial cable from the modem, follow the following
steps:
Connect the coaxial cable with the N or F-type male connectors
to the coaxial connecter equipped with the Unit which is shown
in a figure below under 0.68 to 1.13 N・m torque.

Step 1:
Fixing a ground wire from the common ground of other equipments for
grounding is proceed with the following step:
Fix the ground wire from other equipments to the ground hole
near the coaxical connector with enclosed on the Unit which is
shown in a figure below.
To reduce the risk of damage or broken by lightning surge, the
Unit should be fixed with the ground wire.
