The standards of the country where it is used.
  • Page 94 Storage capacity defines how many points of track and marks a memory can hold. The Waypoint GP-90's storage capacity is 2,000 points. A waypoint is a particular location on a voyage whether it be a starting, intermediate Time-to-go (TTG) or destination waypoint.

    This equipment contains complex modules in which fault diagnosis and repair down to component level are not practical (IMO A.694(17)/8.3.1). Only some discrete components are used. FURUNO Electric Co., Ltd. believes identifying these components is of no value for shipboard maintenance; therefore, they are not listed in the manual. Major modules can be located on the parts location photos on the next page.
