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.

• Use line-of-sight radio

communication (page 10).

• The Astro can track up to 10 dogs

with DC 40 collars. Only three dogs

can be viewed at one time on the

Dog Tracker page. To reduce the

text size, press MENU, and select

Small Numbers.

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).
