5.  GPS OPERATION

Cold start, which clears the Almanac from the GPS receiver, can be necessary in the 
following conditions:

•  If you have turned off the power of the GPS receiver for a long time.
•  The ship has moved far away from the previous fixing position (e.g., more than 500 

km).

•  Other reason that prevents the receiver from finding its position within five minutes 

after you turn on the power.

To cold start, do the following:

1. Press the MENU key to open the menu.
2. Use S or T to select [GPS] and press the ENTER key.
3. Use S or T to select [Cold Start] and press the ENTER key.

4. Use S or T to select [Yes] and press the ENTER key. After processing cold start, 

the long beep sounds. (To stop cold start, press the CANCEL/HL OFF key instead 
of the ENTER key.)

5. Press the MENU key to close the menu.
