Operating Instructions
P7840 Deerchaser ™
Congratulations on your purchase of the
Deerchaser™. Please read the instructions fully
before use. Cared for properly, the Deerchaser™
will provide years of service.
Protect your home and family from intrusive deer
with the new Deerchaser™. This proprietary
technology, developed and field tested by a PhD
and author of several books, will gently ward off
deer – keeping them at a safe distance from
those expensive plants and shrubs.
Keeping deer at a safe distance from our
plantings is one of the more difficult obstacles that
Mother Nature has cast upon us. That, coupled
with the fact that deer carry disease-ridden ticks,
is the perfect reason for Deerchaser™.
WARNING
ã=Unit can be heavy with batteries installed. Mount unit
properly or injury may occur.
ã= When mounting use proper hardware. Do not over
tighten. Breakage may occur.
ã= Do not pierce any plumbing or electrical equipment
when you mount the unit. Damage or injury may occur.
ã= Be sure battery compartment door is securely
closed. Do not open battery compartment if the unit is
wet. Otherwise water may enter and damage the unit.
Injury may occur.
ã= Do not stare directly into the light source. Light is
very bright and may cause discomfort or injury.
ã= Do not place your ear directly to the sound source.
Sound can be very loud and may cause discomfort or
injury.
ã= Only use quality alkaline or lithium batteries in unit.
Other battery types may leak or explode causing injury.
Do not mix old and new batteries.
ã=Dispose of exhausted batteries properly.
ã= When not using the unit for an extended period,
remove the batteries. Stored batteries may leak and
cause damage or injury.
DEERCHASER™ (FRONT)
Parts Identification (see diagram):
a. LED lamp: Super-bright LED light source will
illuminate when the Deerchaser™ signal is
activated.
b. Loudspeaker: Powerful weatherproof speaker
will sound FM broadcast radio when the
Deerchaser™ signal is activated.
c. Passive Infra-red motion detector (PIR) lens.
The PIR features a range of approximately 25 feet
at an angle of 110°.

Control Legend (see diagram):
Remove thumbscrew on rear of unit to access
battery/control compartment.
1. Battery compartment: Insert 3X “D” cell alkaline or lithium
batteries. Be sure to follow the polarity diagram and insert
the batteries correctly. Do not mix old and new batteries.
2. SENS: Adjust the sensitivity of the PIR motion detector.
Typically leave it set at maximum (fully clockwise). To
reduce the coverage area rotate the control counter-
clockwise.
3. Time: Adjust the duration of the Deerchaser™ signal.
Adjust from a minimum of approximately 15 seconds to a
maximum of approximately 7 minutes. After the set time, the
Deerchaser™ will reset and await the next activation.
4. RESET: Restart automatic radio tuning from the lowest
FM frequency (88.3 MHz).
5. Volume: Rotate the knob down to increase the volume of
the Deerchaser™ signal. Typically leave it at maximum
volume to increase effectiveness. If necessary rotate the
knob up to reduce the volume. Rotate the knob all the way
up until it clicks to turn off the unit.
6. TUNNG: Advance automatic radio tuning to the next
received FM frequency. When you have reached the end of
the FM tuning band (107.9 MHz) you will note the received
signal will no longer change. Press the RESET button to
restart tuning at the lowest frequency.
Use:
Remove thumbscrew on rear of unit to access
battery/control compartment.
Insert 3X D cell batteries. Insure correct polarity by following
the diagram. Use only new high-quality alkaline or lithium
cells. Rechargeable batteries are not recommended.
Dispose of exhausted batteries properly.
Rotate the volume control (Volume) downwards to turn on
the unit.
If necessary, wave your hand in front of the PIR lens to
activate the unit.
Press the tuning button (TUNNG) to automatically scan the
FM tuning band to receive an appropriate strong FM
broadcast signal. Repeatedly press the tuning button to
choose your station. Press the reset button (RESET) to
reset the tuning to the lowest frequency. Test reception by
setting unit down and removing your hands. When the unit
is close to your body, tuning sensitivity can change.

BATTERY/CONTROL COMPARTMENT
Rotate the time duration control (Time) to the desired
setting. Shorter durations will extend battery life while
longer durations will have more effect on persistent pests.
Experiment with this setting for best results.
Rotate the sensitivity (SENS) control to the desired setting.
Typically leave it set at maximum (fully clockwise).
Re-install battery door and secure with thumbscrew. Insure
the battery door is fully seated around the entire panel.
Insure thumbscrew is tight to insure weather resistance. Do
not over tighten.

Mounting (see diagram):
A. Use the included screws or other hardware to mount the
base plate to a suitable mounting surface.
You can attach the plate to a fencepost, structure, tree, etc.
Be certain not to pierce any plumbing or electrical
equipment when you mount the base plate.
Mount the base plate with the screw holes vertical. The
Deerchaser™ unit is designed to mount to the base plate
vertically. We do not recommend mounting the unit
horizontally. The sensor will not work properly.
Choose your mounting location carefully. The base plate
allows you to adjust the angle of the Deerchaser™ up or
down. We suggest mounting the unit high enough that it is
out of the reach of children. You can adjust the angle of the
base plate down to protect the intended area.
B. Attach unit to base plate by sliding mounting clip into
matching slot on rear of unit. Then slide unit down on the
clip until it is fully engaged. Be sure clip is fully inserted in
slot.
C. Rotate unit up and down to reach desired mounting
angle. Base plate does not rotate from left to right, only up
and down. PIR motion sensor has a wide angle of
detection. Typically side to side adjustment is not
necessary.
Aim the Passive Infra-red motion detector (PIR) lens
towards the protected area. The PIR features a range of
approximately 25 feet at an angle of 110° (see diagram). If
possible, aim the sensor at an area with fewer branches
and/or vines. Branches moved by strong breezes may
trigger the motion detector circuit. This is normal but should
be minimized to extend battery life.
The Loudspeaker and LED lamp have a longer range than
the PIR. Once the signal is activated, the protected area will
be larger than the PIR range.

MOUNTING THE DEERCHASER™ (SIDE)
Advice:
Choose a strong local FM signal if possible. FM reception
conditions will vary with time of day and weather conditions.
When possible choose your FM signal during the day.
Typically reception is weaker during the day.
Choose an FM broadcast signal featuring “talk radio” or
news broadcasts if possible. Experiment with different FM
broadcasts and observe results.
Use the maximum volume level possible in your application.
Louder signals will be more effective.
When possible, mount the unit under cover. While the unit
is weather resistant, shield it from direct sunlight and rain
when possible.
If possible, aim the PIR motion sensor at an area with fewer
branches and/or vines. Branches moved by strong breezes
may trigger the motion detector circuit. This is normal but
should be minimized to extend battery life.
