on. To leave this screen, press the CLR key. This also puts your changes
into effect.
To turn these changes off, return to this screen and press the key next to
the "PCF Mode ON OFF" label. Remember, presetting the unit also erases
any PCF offset, thereby turning it off.

POSITION FILTER

No matter what kind of radio
navigation input you're using
with this mapping unit, "jitter" or
small position changes will
show on the display even when
you're not moving. For ex-
ample, if the GPS module or
antenna is mounted high above
the deck, position changes will
occur as the boat rolls in the
waves. The position filter will
average the jitter, showing a
smoother position and naviga-
tion display. (The jitter affects not only the position, but all other displays
including course over ground and speed over ground.) There are three
settings: off, low, and high. When the unit is first turned on or is preset, the
filter is turned off. To set the filter, press the MENU key three times. The
screen shown above appears. Now press the key next to the "Filter" label
until the check mark is on the desired setting. Press the CLR key to exit this
screen and put your change into effect.
SIMULATOR
The GlobalMap 2000 has a GPS and sonar simulator feature that shows
your present position travelling a preset course from Miami, Florida. All
navigation and sonar features of the unit operate, also. A recurring
message appears alerting you that the simulator mode is enabled. DON'T
USE THIS UNIT FOR NAVIGATION WHEN THE SIMULATOR IS OPER-
ATING!
To turn the simulator on, press the MENU key three times. Now press the
key next to the "GPS / Sonar Simulator" label. The screen clears and the
simulator begins operation. To turn the simulator off, either repeat the
above steps or turn the unit off.
