NOTE: The DC 40 does not transmit
its location to the Astro, and the
Astro does not indicate the location
of the DC 40, until both devices have
acquired satellite signals.

Communication with the DC 40

The DC 40 that was packaged with
your Astro was linked with the Astro
at the factory. If you are using a DC 40
that you purchased separately, follow
the instructions for adding a new dog
on page 9 to establish communications
with the Astro.

About the Dog Tracker Page

The dog you are tracking is identied

and the dog pointer indicates its
direction from you. The dog pointer is
most accurate when you are holding
the Astro level and the dog is farther
than 30 feet (9.1 meters) away. At less
than that distance, “NEAR” appears
instead of a distance and the dog
pointer is shortened.

NOTE: When you are close to the dog,
the dog pointer may be inaccurate.

*The unknown status icon indicates
that the DC 40 has not acquired a
satellite signal and that the Astro
cannot determine the location of the
dog.

Adding Dogs

The Astro can track up to ten 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. Press DOG > MENU.

2. Select Dog List > <Add New>.

3. Follow the on-screen instructions.

About the Map

When the map orientation is Track Up,
objects on the map appear to rotate
around your position. As you move,
the entire map reorients in the direction
you are facing. To stabilize the objects,
set the orientation to North Up
(page 40).

Dog Signal Troubleshooting

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.

Tracking Your Dog

By default, the new dog is named
“Dog” and an ID number is
randomly assigned.

When possible, you should allow the
Astro to automatically assign IDs. If
necessary, you can manually assign a

1. Press DOG > ENTER > MENU.

2. Select Change Collar Lock PIN.

3. Enter a unique PIN.

NOTE: If you forget the PIN, the
Collar Lock feature can be overridden

acquire satellites before you put the
DC 40 on your dog.

This allows the DC 40 to acquire
satellite signals much faster.

Tracking Your Dog

About Line-of-Sight Radio Communication

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-of­sight conditions, move to the highest elevation point in your area (for example, on
the top of a hill).

FCC Information

Read this information before using
your Astro 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

Important Safety and Product Information

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

66 Astro and DC 40 Owner’s Manual

Important Safety and Product Information

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 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

Astro and DC 40 Owner’s Manual 67

Important Safety and Product Information

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

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
