    The DD-80 takes about two minutes to find position when turned on for the very first time. Other times it takes about 20 seconds. Note: The GPS provides highly accurate po- sition information. However, position should always be check against other aids to naviga- tion to confirm reliability, for the safety of vessel and crew.

    Mount the unit as high as possible. Mounting the antenna as high as possible keeps it free of water spray, which can intercept reception of GPS satellite signal, if water spray is frozen.

    The figure below shows the connection of cables on rear of display unit. Antenna Unit GPA-019S GPA-018S GPA-017S 20cm External Equipment Grounding The display unit contains several CPUs. While they are operating, they radiate noise, which can interfere with other radio equipment. Ground the unit as follows to prevent it.

  • Page 101 Rate of operation The TX rate or operation is the percentage of data output in one second, and it appears on the screen. If short intervals are assigned to many sentences, the rate of operation increases as illustrated below. A rate of operation exceeding 100% is impractical. For better performance, the rate of operation should be less than 90%.
