cropped-stacked-DG-logo.jpgYour Dog Guard dealer has selected the equipment that will accommodate your pet’s
temperament and personality. In addition, your dealer has worked with you to design a
containment area that provides a safe area for your pet and perhaps to keep your pet away
from flower beds, pools and other specified areas.

It is highly recommended that you keep your system operational at all times. Should the
system ever be down for any length of time, it could result in serious problems. PLEASE
check your system periodically, weekly or bi-weekly. Your trainer will go over this
with you and it is explained further in this manual.

Do not wait until your pet leaves the property before calling your dealer!

If your pet does leave the property, call your dealer as soon as possible and
speak with a technician or trainer. Failure to notify your dealer could result in voiding any
containment guarantees and will result in charges for service calls to get your pet back on
the system.

Before you begin, please fill out the warranty card at the back of this manual.
You will need to have a card on file with the manufacturer in case anything was to happen
to your system.

To familiarize you with the equipment, we have prepared this
easy to understand equipment section.

Each outside Dog Guard system consists of a Transmitter, AC
Adaptor, a Surge Protector and at least one Receiver. Let’s look
at each piece of equipment on the following pages


T-4 Transmitter


The T-4 Transmitter comes with an AC adaptor the plugs into the jack on the side of the
transmitter. When the transmitter is operating properly the green power LED is lit as well
as the rest loop indicator led. The yellow fault led will not be lit.
GREEN LIGHT – This light should be ON, make sure the ON/OFF switch located on the
side is ON. Make sure the AC adaptor is plugged into the transmitter properly indicating
there is power to the system. If the Green light is NOT ON, check the outlet with a working
lamp or electronic device to see if the outlet is working. If it is working, you need to call
your local dealer.

RED LIGHT – This light should be ON, indicating your loop is intact, (no breaks) and the
system is operating properly. If the red light is NOT ON, and you are hearing the audible
alarm, it most likely indicates that you have a wire break or even a power surge and you will
need to contact your local dealer to have it repaired.

YELLOW LIGHT – This light should be OFF. A yellow light indicates that the system
is not functioning (possibly due to a power surge, lightning strike or a component in the
transmitter has failed). If the Yellow light is ON, it sometimes will be accompanied by an
audible alarm. Call your local dealer immediately to fix this issue.

T-4 Transmitter

There are 2 adjustments on the transmitter. You will need a small flathead, regular screwdriver
or a transmitter tweaking tool to make any adjustments.


A. Adjust the Field Width or Range Control (left side). The signal field width
determines how close to the wire your pet can go. The normal setting will be about 6 feet.
If you need to adjust the width of the signal field, use an adjusting tool or small screwdriver.
Turn the range adjuster to the right to increase the signal field and to the left to decrease
the signal field. Be sure to remove the receiver from your pet before adjusting the signal.
Check the receiver at the line to assure that the desired width is obtained.

B. Adjust the Correction Level (lower right face). There are 32 levels of stimulus
within the range. This is preset by your dealer for your pet based on several factors, but can
be raised if a pet is challenging the system.

It is recommended that you call your local dealer
before adjusting the field or correction level.

Surge Protector


In order to obtain a lifetime warranty for storm surges or lightning damage,
your system must be installed with a Dog Guard Surge Protector (DGSP). Our
surge protectors protect against normal AC power surges and lightning strikes and will
automatically disconnect the transmitter in case of a rare catastrophic surge or a direct
lightning strike.

Some of the features of the Dog Guard Surge Protectors are:
• Space Saving Design – Low profile and better balance and stability
• Power Indicator Light – Easy to see that the power light is on
• Reduces the Risk of System Failure – Your pet will continue to be contained
• Better Loop Connectors – Easier to attach the loop wires to the unit
• Increased Surge Current Ratings – Protector has a larger capacity
to dissipate surges


Indoor Room Transmitter

The Indoor Room Transmitter works much the same as the outside transmitter. The signal field radiates outward around the unit at an equal distance in ALL directions (front, back and sides, see diagram on page 16). This may vary slightly due to the receiver and/or the transmitter fluctuating in sensitivities as well as the placement and height of the unit.

Normally your only limitation is ensuring the unit is within 10 feet of an outlet (Always remove your pet’s receiver collar before setting unit up or plugging the unit in!)
The easiest way to set up your room transmitter is to place 5
it in the center or near the problem area, plug it in, make adjustments and/or relocate the
unit as necessary. Try to keep the unit at your pet’s height if possible.

Take your pet’s receiver collar in your hand and clip the buckle together. Then holding by the clip or buckle, approach the area just as if your pet would if he/she were wearing it at the same height and angle.

Move the transmitter itself or turn the range control up or down to get the desired effect,
keeping in mind that the signal can travel through walls, floors and any other objects
within the radius you have set. Test all around (360 degrees) to make certain your pet does
NOT get corrected in any safe zones and IS getting the tone in the desired areas. This can
sometimes be a little tricky but you can usually get the desired effect. (You may need to turn
the transmitter on its side, front or back to change the field slightly).
Once your pet is trained to the desired area, you can move the transmitter to other problem
Your new room transmitter has 2 lights and 2 recessed adjustments on the front of the unit.
The lights above the adjustments will get brighter as you increase the corresponding level.
Correction Level – This control adjusts the actual correction your pet receives. Start out
low. If you need to increase the level, do so in small increments.
Range Control – This control sets the distance from the unit that the receiver collar will
activate. Low would be approximately 6 inches and high would be 6 to 8 feet.
Note: Older units work the same as described above except there is no correction adjustment.
