fields are linked. Resetting one of these options in a
user-selectable field will automatically reset the corre-
sponding data in the other. This ensures that informa-
tion shown in these fields reflects your current trip.
Maximum Speed Field
To obtain the most accurate reading of average
speed, keep in mind that due to the sensitivity of the
GPS 12’s antenna, your maximum speed value may
include the effects of rapid movement, such as swinging
your arm while holding the unit.

1. Highlight the ‘MXSPD’ field, and press
E
.
2. Press
E

Altitude Field
When the GPS 12 is acquiring satellites or navigat-
ing in the 2D mode, the last known altitude is used to
compute your position. You may also manually enter
your altitude for greater accuracy. In cases where the
GPS 12 has 2D coverage, entering your approximate
altitude will enable the receiver to determine a more
accurate position fix.
To enter an altitude:
1. Highlight the ‘ALT’ field, and press
E
.
2. Enter a value, and press
