Acquiring satellite signals can take a
few minutes.
1. Go outdoors to an open area, away
from tall buildings and trees.
2. Press and quickly release .
The status page appears. The
bars indicate satellite strength.
3. Wait for the DC 40 to acquire
satellite signals.

Calibrate the electronic compass
outdoors. Do not stand near objects that
inuence magnetic elds, such as cars,
buildings, or overhead power lines.
The Astro has a 3-axis electronic
compass. You should calibrate the
compass after moving long distances,
experiencing temperature changes, or
changing the batteries.
1. From the main menu, press DOG >
MENU.
2. Select Calibrate Compass > Start.
3. Follow the on-screen instructions.

The Astro can track up to 10 dogs
with DC 40 collars. If you purchase
additional DC 40 devices, you can link
them to the Astro. To link, the Astro
must be close enough to the DC 40 to
touch it, or you must know the DC 40
ID number.
1. From the main menu, press DOG
twice.
2. Select Add Dog.
3. Follow the on-screen instructions.
By default, the new dog is named
“Dog” and an ID number is
randomly assigned.

An error message could appear if there
is a conict with the ID number of
another dog.

Each dog you track has its own ID
number. If two dogs within range of
the Astro have the same ID, the Astro
warns you of a conicting ID signal.
Follow the on-screen instructions to
resolve the conict.
When possible, you should allow the
Astro to automatically assign IDs. If
necessary, you can manually assign a
new ID number to a dog.

This requires wireless communication
with the DC 40. You must turn on
the DC 40 and bring it within range
of the Astro. You must assign a new
ID number to the dog and change the
update rate.
1. From the main menu, press DOG
twice.
2. Select a dog.
3. Select Show Info.
4. Press MENU.
5. Select Comm. Settings.
6. Select an unassigned and
nonconicting ID.
7. Change the update rate (optional).
Both 30-second and two-minute
rates reduce battery drain, but they
create a less-detailed dog track and
collected statistics.
8. Bring the Astro within a few feet of
the DC 40.
9. Follow the on-screen instructions.

• Turn on the DC 40 and allow it to
acquire satellites before you put the
DC 40 on your dog. This allows the
DC 40 to acquire satellite signals
much faster.
• Bring extra AA batteries for your
Astro.
• Use a fully charged DC 40. A
fully charged DC 40 operates for
approximately 17 hours when using
ve-second interval reporting.

The Astro and DC 40 use radio signals to communicate. Objects in the path of
radio signals degrade the quality of the signals. Keeping an unobstructed line of
sight between your Astro and your dog’s DC 40 produces the best communication
signal. Obstructed radio waves result in a poor signal. To achieve the best line-of-
sight conditions, move to the highest elevation point in your area (for example, on
the top of a hill).
