high-temperature location, such as in the sun in an unattended
vehicle on a hot day. To prevent damage, remove the unit from the
vehicle or store it out of direct sunlight, such as in the glove box.

Do not incinerate the DC 30 or the battery.

•

•

When storing the unit for a limited length of time, store within

the following temperature range: from -4˚F to 104˚F (from -20˚ to
40˚C). When storing the unit for an extended time, store within the
following temperature range: from 32˚F to 77˚F (from 0˚ to 25˚C).

Dog Tracking

This section describes communications between the
DC 30 and the Astro, tracking dogs on the map, and
adding dogs to the Dog List.

When communicating with the DC 30, the Dog Tracker
page indicates the direction of the dog, the distance away
from you, and the status of the dog. The Astro 220 can
keep track of ten dogs. Use the Rocker to scroll through
the list of dogs.

Communicating with the DC 30

Adding Dogs to the Dog List

If you purchase additional DC 30 units, you can link them
to the Astro 220 using the setup wizard in the Dog List.
To link, the Astro 220 must be close enough to the DC 30
to touch it, or you must know the DC 30 ID number.

To add a new dog to the list:

1. On the Dog Tracker page, press MENU > Dog List >

<Add New> > ENTER to open the setup wizard.

2. Use the Rocker and ENTER to select and conrm
options. By default, the new dog is named “Dog” and
an ID number is randomly assigned.

NOTE: The setup wizard may indicate that there is a

conict with the ID number of another dog. To resolve
the conict, follow the instructions in the setup wizard
and in “Conicting Dog Signals.”

Conicting Dog Signals

Each dog you track has its own ID number. If two dogs
within range of the Astro 220 have the same ID, the

Astro 220 warns you of a conicting ID signal. It then

opens a setup wizard to guide you through the process of

resolving the conict.

If necessary, you can manually assign a new ID number
to a dog. When possible, you should allow the Astro 220
to automatically assign IDs.

12 Astro Dog Tracking System Owner’s Manual

To assign a new ID number to a dog and change
the update rate:

1. On the Dog Information page, press MENU > Change

Comm. Settings.

2. Select an unassigned and nonconicting ID > OK.

3. Change the update rate, if desired. Both 10-second
and 30-second updates reduce battery drain, but
they create a less-detailed dog track and collected
statistics.

4. Ensure that the Astro 220 is within a few feet of the
DC 30.

5. Complete the setup wizard instructions.

Tips for Successful Tracking

Use a fully charged DC 30. A fully charged DC 30

•
operates for approximately 17 hours when using
5-second interval reporting.

•

Use line-of-sight radio communication. The Astro 220
and DC 30 use radio signals to communicate. Objects
in the path of radio signals degrade the quality of
the signals. Keeping an unobstructed line of sight

Dog Tracking

between you and your dog’s DC 30 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).
