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).

Astro Dog Tracking System Owner’s Manual 25

GPS Applications

Using the Course Pointer or the Bearing
Pointer

The bearing pointer indicates the direction to your
destination, and the course pointer indicates your
relationship to a course line leading to the destination.

The course pointer provides an indication of drift (right
or left) according to the scale shown at the edge of the
compass ring. The scale refers to the distance between
dots on the course deviation indicator. The course line to
your destination is based on your original starting point.

The bearing pointer points to the destination, regardless
of the direction you are moving. If the bearing pointer
is pointing in your direction of travel, you are traveling
directly toward your destination. If the bearing pointer
points any other direction, turn toward that direction until
the bearing pointer is pointing ahead.

Long-Term DC 30 Battery Storage:

The normal
long-term decrease in the charging capacity of lithium­ion batteries can be accelerated by exposure to elevated
temperatures. Storing a fully charged battery for more
than three months in a location that exposes it to high

temperatures (above 70°F or 21°C ) can signicantly

reduce its recharging capacity. Before storage, charge the

a cool, dry location where temperatures are not expected
to exceed typical household levels. Do not store a fully
depleted battery because it may not recharge after an
extended period of storage. After storage, fully charge the

IMPORTANT WARNINGS: READ THIS INFORMATION
BEFORE USING YOUR ASTRO 220 DOG TRACKING
SYSTEM:

Exposure to Radio Frequency Signals–Your product is a low power

radio transmitter and receiver. When it is on, it receives and also
sends out radio frequency (RF) signals. In August 1996, The Federal
Communications Commissions (FCC) adopted RF exposure guidelines
with safety levels for handheld wireless radios. Those guidelines
are consistent with safety standards previously set by both U.S. and
international standards bodies: American National Standards Institute
(ANSI) IEEE. C95.1-1992; National Council on Radiation Protection
and Measurements (NCRP) Report 86; International Commission on
Non-Ionizing Radiation Protection (ICNIRP) 1996. Those standards
were based on comprehensive and periodic evaluations of the relevant

scientic literature. For example, over 130 scientists, engineers, and

physicians from universities, government health agencies, and industry
reviewed the available body of research to develop the ANSI Standard
(C95.1). The design of your radio complies with the FCC guidelines
(and those standards).

For body-worn and face-held operation, this radio demonstrates
compliance and meets the FCC RF exposure guidelines for
uncontrolled exposure (general population) when used with approved
accessories supplied with or designed for this product. Use of other
accessories may not ensure compliance with FCC RF exposure
guidelines.

Antenna Care–Use only the supplied antenna. Unauthorized

antennas, modications, or attachments could damage the radio and

may violate FCC regulations. Warning: Do not use any radio that
has a damaged antenna, because if it comes into contact with your
skin, a minor burn can result.

Electronic Devices–Most modern electronic equipment is shielded

from RF signals. However, certain equipment may not be shielded
against the RF signals from your wireless radio.

Pacemakers–The Health Industry Manufacturers Association
(HIMA) recommends that a minimum separation of six inches
(6”) be maintained between a handheld wireless radio and a
pacemaker to avoid potential interference with the pacemaker. These
recommendations are consistent with the independent research by and
recommendations of Wireless Technology Research. Persons with
pacemakers should ALWAYS keep the radio more than six inches
from their pacemaker when the radio is turned on, should not carry
the radio in a breast pocket, should use the ear opposite the pacemaker
to minimize the potential for interference, and should turn the radio
off immediately if you have any reason to suspect that interference is

62 Astro Dog Tracking System Owner’s Manual

taking place.

Hearing Aids–Some digital wireless radios may interfere with some
hearing aids. In the event of such interference, you may want to
consult your hearing aid manufacturer to discuss alternatives.

Other Medical Devices–If you use any other personal medical device,
consult the manufacturer of your device to determine if it is adequately
shielded from external RF energy. Your physician may be able to assist
you in obtaining this information.

Turn your radio OFF in health care facilities when any regulations
posted in these areas instruct you to do so. Hospitals or health care
facilities may be using equipment that could be sensitive to external
RF energy.

Vehicles–RF signals may affect improperly installed or inadequately
shielded electronic systems in motor vehicles. Check with the
manufacturer or its representative regarding your vehicle. You should
also consult the manufacturer of any equipment that has been added to
your vehicle.

Posted Facilities–Turn your radio OFF in any facility where posted
notices so require.

Commercial Aircraft–Many commercial airlines prohibit the use of
FRS/GMRS radios on board. Switch OFF your radio before boarding
an aircraft or check the airline rules.

Blasting Areas–To avoid interfering with blasting operations, turn
your radio OFF when in a “blasting area” or in areas posted: “Turn off
two-way radio.” Obey all signs and instructions.

Potentially Explosive Atmospheres–Turn your radio OFF and do
not remove your battery when you are in any area with a potentially
explosive atmosphere. Obey all signs and instructions. Sparks from

your battery in such areas could cause an explosion or re resulting in

bodily injury or even death.

Areas with a potentially explosive atmosphere are often, but not
always clearly marked. They include fueling areas such as gasoline
stations, below deck on boats, fuel or chemical transfer or storage

facilities; vehicles using liqueed petroleum gas (such as propane or

butane); areas where the air contains chemicals or particles, such as
grain, dust, or metal powders; and any other area where you would
normally be advised to turn off your vehicle engine.
