This manual will provide you, the user, with directions for the safe and ecient operation
of the Yard Sentinel™. Please read this manual carefully before using this product, and
keep it for future reference.
IMPORTANT!
Before you plug in your unit, it is important to understand sonic and ultrasonic signals.
The sonic signal is the alarm/harrassment sound humans can hear. Combining this sound
with ultrasonic may give you better results for startling and repelling intruders and pests
from your yard. However, if the sonic sound bothers your neighbours, you can turn this
o using the “Sonic Volume” dial. Just turn the volume dial to zero.
The ultrasonic signal is the high-pitched frequency that only animals can hear. This sound
will be emitted whenever your device is on (plugged in or on battery power). You can
adjust the ultrasonic frequency using the Frequency dial, but you won’t turn it o by
adjusting either the Sonic Volume or Frequency dial.

the screws and hang the unit.
If installing the unit outdoors, place it at the height of the pests if possible. If not, tilt the
unit downwards slightly to capture the pests in the device’s eective range (see diagram
on page 6). The unit must be aimed at the direction of the pests with no objects (e.g.
windows, walls or fences) in front of it.
Training a Pet:
Some people try the Yard Sentinel™out on their pets to see if it works or to train their pet
not to enter a particular area. It’s important to remember that your pet is used to living
comfortably in your home. He may be annoyed by the sound, but he may not be deterred
from the room. As far as he is concerned your home is his proper place. An outdoor
animal on the other hand is sensitive to noise and alert to danger. The same way an alarm
will repel an intruder, the ultrasonic signal will repel an unwanted animal.
If you want to use the ultrasonic device to deter your cat or dog from a part of the
house, you may have to train them. When the device activates, show them what to do.
Demonstrate to them that it’s time to leave the room when they hear the noise and that
doing this will stop the noise. Dogs will, of course, be easier to train than cats.
Note: Just like your pet, wild animals will have certain habits and behaviours that can
change over time. If they are accustomed to nding food in your backyard, they may
continue to come even if they are disturbed by the ultrasonic, especially if they can’t nd
food elsewhere. The Yard Sentinel™ is designed to work in combination with other good
pest management practices.
Here are some preventive measures you can take to keep pests out of your home
and yard:
1. Keep garbage lids closed tightly.
2. Store food in airtight containers.
3. Don’t leave pet food and water out overnight.
4. Repair plumbing leaks and cracks.
5. Drain all liquids and wash containers before you put them in the recycle bin.
6. Accumulating paper products such as cardboard boxes, bags, newspapers, etc.,
should be avoided.
7. Keep grass short around the foundation of the house and the trees and shrubs
planted away from the house.
8. Screen all vent opening such as crawl spaces, attics or laundry vents.
9. Repair and adjust windows and door screens.

It can also be powered by a vehicle’s “cigarette lighter” power outlet with our special
adapter cord (Fig. 9) (NOT INCLUDED).
For ordering information, see page 11.
In addition, we have 65 ft (20 m) extension cords
available (Fig. 10).
Turning the Yard Sentinel™ on and o:
The Yard Sentinel™ does not have an on/o switch.
To turn it o, unplug it or remove the batteries. To
turn it on, plug it in or insert batteries.
When the unit is plugged in or batteries are
installed, it will trigger a red sensor light within 20 seconds. The light will stay on for
about 20 seconds, after which the device
will be ready to operate.
SETTINGS:
You can customize your device’s settings for
best results in your particular situation. The
ultrasonic setting control switch is located on
the top left of your control panel. Remove the
back cover to access it.
Motion Sensor: The Motion Sensor will
activate the ultrasonic and sonic sounds
when it detects pests within its range.
Constant: This setting will cause the device to emit a frequency at random intervals of not
more than 40 seconds on AC. The pause in between helps ensure the pest does not become
accustomed to the sound. You control the frequency emitted using the Frequency dial.This is
a good setting to use if you only want to repel one type of animal and if the animal sometimes
goes out of range of the motion sensor. (Battery saver: On battery power, the device will
activate for shorter durations at intervals of up to ve minutes to preserve battery life.)
Continuous Sweep: This setting emits cycles of random frequency (approximately from
15kHz to 20kHz) with a break of not more than 40 seconds. This is the ideal setting if you
want to repel two or more dierent types of pests. (Battery saver: On battery power, the
device will activate for shorter durations at intervals of up to ve minutes.)
Frequency Dial:
Various pests have dierent ranges of ultrasonic hearing. Sometimes you will need to
experiment to nd the range that best repels the pest you want to control. However,
the Frequency dial illustrates a range of frequencies and the pests they are eective at
repelling as a guide.
Sensitivity Dial:
The“Sensor Sensitivity”dial controls the detection range of the device’s Infrared Motion
Sensor. You can adjust the range from near to far (5 to 45ft / 1.5 to 14 m). The ideal range
will vary under dierent environments. Try setting it to maximum and reducing it if you
nd the device activates when there is no motion in the area.
Mounting to a Wall:
Two screws and fasteners are included with this unit for mounting on walls. Drill the
screws into a suitable wall or upright surface. Align the notches on the back cover with

QUICK SET-UP
Thank you for purchasing the Yard Sentinel™! You have two options to get your device
started. Your unit came with an AC adapter. Remove the back cover from your device
and plug in the adapter. You will see an opening at the bottom of the unit that you can
run the cord through.
If you don’t have an electrical outlet available in the area, you will need four C batteries
(not included).
When you install power, a red light will turn on after a few moments. The light will stay on
for about 20 seconds and then switch o. Your device is now ready to use.
All of your controls are located at the back of your device. Remove the cover to adjust the
following settings as needed.
Frequency Dial: You will see several types of pests listed
around the Frequency dial (Fig. 1) and the ranges of
frequencies that are ideal for repelling them. You can turn
this dial to the setting that best suits your needs. If you are
trying to repel more than one type of pest, set it somewhere
within the ranges of each of them. Adjust the frequency
slightly every few weeks to avoid the pest adapting to the
sound.
Modes: The Yard Sentinel™ has three dierent modes(g.2).
Try all three to see what works best on the animal you are
trying to repel (see Operating the Yard Sentinel™, page 7).
Motion Sensor: The Motion Sensor will activate the ultrasonic and
sonic sounds when it detects pests within its range.
Constant: The Constant setting will activate the ultrasonic
and sonic noises at a set frequency. The motion detector will
deactivate on this setting.
Continuous Sweep: The Continuous Sweep will activate a range of
random sonic and ultrasonic frequencies. The motion detector
will be deactivated on this setting. This is helpful for repelling several dierent
types of pests.
Sensitivity Dial: The Sensitivity dial adjusts the distance at which the device’s motion
sensor will work.
Sonic Volume: The Sonic Volume adjusts the loudness of the alarm and harassment
sound. If this sound bothers you or your neighbours, turn it all the way down. The
ultrasonic signal will still be eective in repelling pests.
Guidelines to help you get the most out of the Yard Sentinel:
1. With batteries, set the Ultrasonic switch to Motion Sensor. Doing so will considerably
prolong the battery life. Set the Motion Sensor Sensitivity to 20-25 for smaller
animals (squirrels, mice, birds) and 15-20 for larger animals (dogs, raccoons, deer).
2. When plugged-in, use Constant, as it provides the best protection for repelling a
specic type of animal.
3. If you need to repel several types of animals, set the switch to Continuous Sweep;

OPERATING TIME:
Some pests, like birds, are active only in the daytime. Others, like raccoons, are active at
night. You can choose whether to operate your device only in the daytime, nighttime or
all day with the power-saving Operating Time feature (, Page 6, Fig. 6).
OPERATING THE YARD SENTINEL™
Using the A/C Adapter:
Remove the back cover of the unit by
gently pulling it off. Plug one end of
the A/C adapter into the 9 volt D/C jack
located beside the frequency dial. Plug
the other end into any standard A/C
outlet. Thread the A/C adapter cord
through the notch at the bottom of the
unit and then replace the back cover by
snapping it into place (see page 11). If you
do not have a weather-proof electrical
outlet, the adapter should be plugged in
indoors. The device and the 9-volt port are weather resistant, but it is best to protect
the Yard Sentinel™ from heavy rains
or snow.
Connecting the extension cord:
To connect the extension cord, simply
plug in the small side of the extension
cord at the back of the unit where it
indicates D/C 9V, then attach the
other larger plug to the A/C adapter
(Fig. 7).
Installing the batteries:
The Yard Sentinel™ can also operate
on batteries. It uses four size C
batteries. To install the batteries,
remove the back panel by gently
pulling it o. Install the batteries as
shown on the diagram (see page 11)
so the positive and negative poles
match the poles printed on the unit. With the batteries in place, replace the back cover
of the unit by pressing it until it snaps closed.
Intelligent Power System (IPS):
The Yard Sentinel™ is designed to provide uninterrupted protection even during a power
failure. Install four C batteries and plug in your device.Your device will be powered through
electricity. If the power fails, the device will automatically switch to battery backup.
Available Power Source Accessories:
Some of our customers choose to use their device in remote areas without traditional
power outlets. The Yard Sentinel™ can be connected to a 12V D/C Sealed Lead-Acid (SLA)
battery using our special extension cord with alligator clip and D/C power plug (Fig. 8).

the device will then randomly cycle through a whole range of frequencies.
4. It’s advised to leave the unit operating 24HR. However, if required, change the
switch to Night or Day.
5. If you don’t want to hear the device, turn the Sonic Volume all the way down to zero.
6. Find the animal category you want to repel on the frequency dial and point the knob
at the arrow on the left side of that category for birds, skunks, and deer, and on the
right side for rodents, cats, dogs, and bats. Other animals would fall somewhere in
between. Rabbits tend to respond to insects category. Take a look at the diagrams on
Page 11 of this manual for a visual representation.
PLACEMENT:
It’s important to place the device where it will be most eective. For ground animals, like
raccoons, coyotes, etc., place the unit near the height of the animal you want to repel and
facing the area where they most like to frequent. Don’t place it on the ground as this will
limit the eective range of the device. Using the screws, you can hang the unit on a wall,
tree, fence, stairs, or even on top of your mail box. If your device is o the ground and
higher than the animal’s eye-level, tilt it downward somewhat. For animals that nest in trees
– birds or squirrels – place the device on a tree or rooftop. The ultrasonic frequency has a
range of up to 70 ft (21 m), but the closer it is to the animal, the more eective it will be.
Ultrasonic signals cannot penetrate solid surfaces. Make sure there are no windows,
doors, fences or other items between the device and the area you want to cover.
The ultrasonic sound emits in a forward direction from the device with a range of about
170 degrees horizontal and 60 degrees vertical.
THE SCIENCE BEHIND IT
The Yard Sentinel™ comes equipped with a variety of useful features. You will need to
experiment to see which features or combination of features give you best results in
ridding your yard or other open area of pests.
Ultrasonic:
The primary feature of your device is the ultrasonic signal.
This is a high pressure sound that is only slightly audible to
humans. However, it is very eective at startling and scaring
away unwanted pests. Using a variable pulse generator,
the ultrasonic emits a range of uctuating sound waves to
prevent the pest from becoming accustomed to the sound.
Using the Frequency dial: In order to use the ultrasonic
signal to best eect, you will need to become familiar with
the ultrasonic Frequency dial. Remove the back cover from
your device. It should snap o just like a lid. The Frequency
dial is located in the top middle. It is the largest dial (Fig. 3).
You will see a variety of ranges indicated around the dial. These ranges are identied
by the animals they ideally repel. Choose a range that best reects the type of animal
you are trying to repel. Insects and large animals are repelled by lower frequencies
(counter-clockwise). Rodents are repelled by higher frequencies (clockwise).
Fig. 3

Fig. 4
Ultrasonic signals travel in a forward direction. You will need to point the device towards
the area where you are having the pest problem. The signal will range 170 degrees
horizontally and 60 degrees vertically from the unit (Fig 4).
Note: If you have a cat or a dog you may have to turn the device o when they are in the
yard. This depends on the frequency you are using because cats and dogs can have very
dierent levels of hearing depending on age or size. Other types of pets such as rodents
or insects may be more sensitive. Ultrasonic waves cannot penetrate surfaces, so put
them in a box or leave them behind and out of range of the device.
Sonic:
In addition to the inaudible ultrasonic signal, your device
is equipped with a sonic signal. This helps to scare o any
people or pests lurking around your property or large
animals such as bears, coyotes, racoons, skunks and birds.
At full volume, the sound can be heard up to 300 ft (91m)
away. It can also act as a security alarm for your yard.
How to use: The sonic signal is controlled by the Sonic
Volume dial. To turn it up, turn the dial all the way
clockwise. If you nd the sonic noise bothers you or your
neighbours, you can turn it o by turning the volume dial
all the way down (counter clockwise) or simply lower the
volume at your discretion. Adjusting the Sonic Volume will not
aect the ultrasonic signal which emits at a xed rate.
Infrared Motion Sensor:
Your device can be set to activate only when animals come into
range. Set the mode switch to“Motion Sensor”to select this feature.
When an animal or human enters the range of the device within
45 ft (14 m), a red light will go on and the device will activate both
the ultrasonic and sonic. The range of the sensor may vary due to
ambient temperature.
The Motion Sensor is equipped with a dial that controls its sensitivity (Fig. 5). Turn it all the
way up to ensure it works as well as possible (30). If you nd the device activates when
there are no animals in the yard, turn it down to about 25.
Note: You can test your device to see if it is working by switching the mode to “Motion
Sensor” and walking or waving your hand in front. If you see the red light, you will know
the movement has been detected. If the Sonic Volume is turned up, you will also hear the
alarm/harassment noise. The ultrasonic signal may also be slightly audible to some people.
