Caution
1. While New Japan Radio., Ltd.(NJR) continually strives to improve the quality and reliability of any products, failures would occur
in microwave products over time. For this reason, it is important that customers fulfill their responsibilities to ensure designed-insafety – including failsafe functions, redundancy, and measures to prevent malfunctions and the spread of fire – in order to avoid
injuries, accidents, or social repercussions resulting from the failure of any product related to satellite communications on thisdocument (hereinafter, “the product”). Customers must pay careful attention to ensuring the safety of their equipment.
2. The product is designed and tested to function in accordance with its specifications. Do not use under conditions that deviate fromthe product specifications included in the specifications. NJR assumes no responsibility and shall not be liable for any injuries,
accidents, or social repercussions resulting from the product being in a poor or damaged state because it was used underconditions that depart from the specifications.
3. The product is covered by a warranty for one year following delivery unless otherwise stipulated in the contract or delivery
conditions. In the event of a failure for which NJR are responsible occurring during the warranty period, NJR undertake to repair
or replace the product free of charge. Note, however, that the warranty does not cover failures such as those listed here (seebullets below), even if they occur within the warranty period. In addition, in the case of a product being repaired or replaced byus, the starting date for the warranty period is still the original delivery date of the product.
Failure due to the product being used in conditions other than those stipulated in the data sheet, specification sheet, etc.

Failure due to modifications or repairs carried out by some entity other than our company



Failure determined to be the result of unsuitable maintenance or replacement of a consumable item that requires due
maintenanceFailure due to circumstances that were unforeseeable given the scientific/technological standards at the time of shipment

Other failures due to external factors such as fire, earthquake, flood and power supply anomalies for which NJR are notresponsible

In addition, the product warranty is limited to the provision of repair services or replacement at no cost. It does not coversecondary damage (to equipment, business opportunities, profits, etc.) or any other damage that may have resulted from failureof the product.
4. The product must be handled appropriately to ensure its continued reliability. Since it can be damaged by the intrusion of water,
dust, oil, chemicals, etc., it must be given appropriate protection. Even in the case of a product with an airtight construction,
avoid using it in an environment that exceeds the stated levels of waterproofing/dustproofing. Also, be sure to use connectors
and waveguides properly.
If replacement parts such as fans are included, proper maintenance is necessary. To maintain product performance andfunctionality, it is necessary to conduct inspections and maintenance at appropriate intervals and exchange replacement parts
when necessary. Improper inspections or maintenance may result in failure.
In addition, the warranty does not cover the use of the product in areas where salt damage can be expected or where there is a
substantial presence of corrosive gases such as Cl2, H2S, SO2, and NO2. If the product is to be used in such areas, at the time ofinstallation you must take appropriate steps to protect the product.
5. If the product is to be used with equipment/systems that must meet special quality and reliability standards (aerospaceequipment, medical equipment, power generation control equipment, automotive/railway transportation equipment, safetyequipment, disaster prevention and security equipment, etc.), please consult with our sales staff in advance.
6. This product contains gallium arsenide (GaAs), classified as a harmful substance. To avoid danger, do not incinerate, crush, or
chemically treat the product in such a way that gases or dust are released. When disposing of the product, comply with allapplicable laws and regulations and do not treat it as general industrial waste or household waste.
7. When exporting a product or technology, observe export laws and regulations such as those governing foreign exchange andforeign trade, and obtain any necessary licenses for export, service transactions, etc. NJR request that you do not use ourproducts or the technical data published on this document for developing weapons of mass destruction or for any other military
purposes or applications.
8. The product specifications in this document are subject to change without notice. If you are considering using a product, delivery
specifications must first be settled.
