 Hold the units in front of you with the antennas

held upward. While the Astro 220 GPS receiver is

searching for the satellite signals, observe the GPS

Signal Strength bars in the Status Bar at the top of

the page. When the receiver has signals from at

least three satellites, the GPS bars fill to indicate 

signal strength and a location fix, while the LED 

on the DC 20 double blinks at each pulse when a

location fix is achieved.

It is recommended that the Astro 220 compass be 

calibrated the first time you use it, after periods of 

storage, after you install new batteries, or when exposed 

to temperature changes of greater that 20

o

 F.

Calibrate the electronic compass outdoors. The accuracy 

of the electronic compass is adversely affected if the unit 

is not held level or you are near objects that generate 

magnetic fields, such as cars or buildings.
