Try this:
Check Sat Schedule with AUX 2. If the
window of availability for 3D opera-
tion is insufficient, try operating in
2D or Automatic.
The mask angle is set to 15
°
or 20
°
. Avail-
able satellites have lower elevations.
Do this:
Change the mask angle with SETUP.
Usually, a mask angle of 10
°
is suffi-
cient.
OPERATING TIPS
General.
Most equipment malfunctions can be prevented by observing the
following rules:
•
Turn the unit off before inserting or removing a power jack.
•
Do not leave the unit face up in the sun.
•
Do not operate the unit in temperatures above 60
°
C or below
-10
°
C.
•
Do not store the unit at temperatures above 70
°
C or below
-40
°
C.
•
If the unit is dropped in the water, use fresh water to carefully
rinse both the outside of the unit and the battery compartment.
Dry the unit and battery compartment thoroughly.
Unsure of Your Position When Initializing.
When you want to initialize
the unit, but do not know your current position and have no map to refer to,
self-initialize with AUX 9 or POS. AUX 9 initiates Almanac Collect, and
accepts the first position fix computed as the initial position. (This is
described more fully in
AUX 9
.) (Be sure you have a clear view of the sky.)
An initial position entered in this way is sufficient to operate the unit, but the
unit will obtain its first position fix much faster if it is initialized by manually
entering the position.
If you know where you were, you can use Waypoint Projection (AUX 6) to
project your current position and date.
