For service maintenance availability of the products oriented for ocean-going merchant marine market, we have, in principle, secure 10 years after their production is terminated, based upon the guideline from the Japan Marine Equipment Association (JSMEA) document, "Guidelines for Navigation and Radio Communication Equipment Maintenance". For the products oriented toward fishery as well as leisure marine market segments, we have secured several years of service maintenance availability after the termination of production. Nevertheless, we shall try our utmost to provide service maintenance of the product as far as possible, but please note that this shall solely depend upon availability of the spare parts, which may be rather difficult to secure the stock. If such is the case, we may well present you with alternative solution. We thank you very much indeed for your understanding.
