Caution Information
1. New Japan Radio Co., Ltd (NJR) strives to produce reliable and high quality microwave components. NJR'smicrowave components are intended for specific applications and require proper maintenance and handling.
To enhance the performance and service of NJR's microwave components, the devices, machinery orequipment into which they are integrated should undergo preventative maintenance and inspection at
regularly scheduled intervals. Failure to properly maintain equipment and machinery incorporating theseproducts can result in catastrophic system failures.
2. To ensure the highest levels of reliability, NJR products must always be properly handled. The invasion of
external contaminants (e.g. dust, oil or chemical compound) can result in failures of microwave components.
3. 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 canresult 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.
4. The products listed in this document 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 orsales 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
5. NJR 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 NJR's sales office or sales
representatives, if you are uncertain about the products listed in this document.
6. NJR's products have been designed and tested to function within controlled environmental conditions. Do not
use products under conditions that deviate from methods or applications specified in this document. Failure
to employ NJR's products in the proper applications can lead to deterioration, destruction or failure of theproducts. NJR shall not be responsible for any bodily injury, fires or accidents, property damage or any
consequential damages resulting from the misuse or misapplication of its products. PRODUCTS ARE SOLDWITHOUT WARRANTY OF ANY OF KIND, EITHER EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TOANY IMPLIED WARRANTY OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE.
7. The product specifications and descriptions listed in this document are subject to change at any time, withoutnotice.
