& Altitude Fields
Maximum Speed Field
To obtain the most accurate reading of your maxi-
mum speed, keep in mind that due to the sensitivity of
the GPS 12CX’s antenna, your maximum speed value
may include the effects of rapid movement, such as
swinging your arm while holding the unit.
To reset the maximum speed field:
1. Highlight the ‘MXSPD’ field, and press
ENTER.
2. Press
ENTER to confirm the ‘RESET?’ prompt.
Altitude Field
When the GPS 12CX is acquiring satellites or navi-
gating in the 2D mode, the last known altitude is used
to compute your position. You may also manually en-
ter your altitude for greater accuracy. In cases where
the GPS 12CX has 2D coverage, entering your approxi-
mate altitude will enable the receiver to determine a
more accurate position fix.
To enter an altitude:
1. Highlight the ‘ALT’ field, and press
ENTER.
2. Enter a value, and press
ENTER.
Position Field
The GPS 12CX displays the current GPS location in
degrees-minutes -decimal minutes (default) or a vari-
ety of user selectable position formats. See page 39 for
more information on user selectable position formats.
12/24 Hour Clock
The GPS clock can be configured to display in a 12
or 24 hour format. For more information on setting up
the clock see page 37.
