Differential GPS Trafc Light Operation:

Red Flashing

Not tracking satellites (no position update). This

is normal for the first 2 minutes or so when turning the

unit on. The very first time you turn the unit on, or if

the memory is reset or lost, this condition is also nor-

mal. Allow the receiver to run for at least 30 minutes

under these circumstances. If it still does not change

to Red Solid, refer to the troubleshooting section in the

Installation section of this manual.

Red/Yellow Solid

Dead Reckoning. When normal GPS or DGPS operation

is not available, this LED sequence is provided to quickly

identify the DR navigation mode. A DR indicator is also

displayed on all screens.

Red Solid

Tracking one or more satellites (no position up-

date). This is also normal for the first 2 minutes or so

when turning the unit on. The very first time you turn the

unit on, allow the receiver to run for at least 20 minutes

after changing to Red Solid to collect an almanac from

the satellites, regardless of whether a position update

has been calculated or not. This is also a normal indi-

cation if the HDOP is greater than 10, if the receiver is

tracking too few satellites, or for other reasons as well.

Read the GPS and DGPS function screens for more in-

formation.

Yellow/Green Solid

GPS position update; DGPS corrections are not be-

ing received. You may see this from time to time during

normal operation. It usually occurs when the beacon

signal is not available (either it is being blocked by terrain

or a local object or you are out of range of the transmit-

ter) and/or you are tracking 3, 4, or 5 satellites, and the

satellites have poor geometry relative to your position.

The condition will normally go back to green solid, when

it picks up another beacon station. The factory default
