- 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 we are not responsible
- (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 and functionality, 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 of installation 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 (aerospace equipment, medical equipment, power generation control equipment, automotive/railway transportation equipment, safety equipment, disaster prevention and security equipment, etc.), please consult with our sales staff in advance.
- (6)Some products contain 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.
