Closely observe your dog when determining the right
training method to use with your Dogtra product.

Nick/Constant Button
There are three buttons each on the front and left side
of the transmitter. The Nick/Constant button is the
top button on each side of the transmitter. When the
button is pressed quickly, the Nick function is activated
and the receiver emits a single rapid pulse of electrical
stimulation. When the button is pressed more than two
seconds, the Constant function is activated and the
receiver emits a continuous stimulation as long as the
button is pressed, for up to 12 seconds. If the button
is not released after 12 seconds, the stimulation will
automatically turn off as a safety feature. The receiver
will be ready to be reactivated once the button has been
released.

The Antenna Hinge is an accessory that
extends the original range that can be
lost from touching the user's body or
interference from surroundings. This
accessory also bends in a 180 degree
direction in order to prevent antenna
breakage from high physical activity or
from bending over.
3. Antenna Hinge
1) Remove the antenna from the transmitter by turning it
counterclockwise.
2) Place the Antenna Hinge in the antenna base and turn
clockwise.
3) Insert the antenna into the Antenna Hinge and turn
clockwise.

15
Proper Fit
The receiver should be fitted so that the surgical
stainless steel contact points press firmly against
the dog’s skin. You should be able to fit two fingers
underneath the collar strap. The best location is on
either side of the dog’s windpipe.
Improper Fit
A loose fit can allow the receiver to move around on the
dog’s neck. When this happens, the contact points may
rub against the skin and cause irritation. If the receiver
is too loose, the contact will not be consistent and cause
the corrections to be inconsistent. Dogtra uses surgical
stainless steel contact points and anti-microbial plastic
to protect the dog’s skin.
4. Receiver Fitting

16
Attention!
Leaving the receiver in the same location on the
dog’s neck for an extended period of time can cause
skin irritation. If the dog is to wear the e-collar for
long periods, occasionally reposition the receiver
so that the contact points are moved to a different
location on the dog’s neck. Make sure you check for
skin irritation each time you use the unit.
Intensity Selection
The 3500X has a Selector Dial on the top of the
transmitter (1 is the lowest and 8 is the highest).
Remember that you will need to adjust the setting
(upward or downward) depending on your dog’s
temperament and threshold for stimulation. Always
start at the lowest level and work your way up. The
appropriate level can be found when the dog responds
to the stimulation with a mild reaction. Also, as the dog’s
attitude changes, especially during times of increased
excitement or distraction, you may need to adjust the
intensity level.
Note: The stimulation intensity can be adjusted even
when the stimulation is in use.
5. Finding the Right Stimulation

17
The 3500X has a 1.5-mile range. Depending on the way
you use your transmitter, the transmitter range may vary.
To get the greatest range, hold the transmitter away
from your body and avoid touching the antenna. Keep
your unit properly charged for maximum signal strength.
Typical range
Maximum range Minimum range
6. Maximizing the Distance

18
The LED indicator flashes every 4 seconds when the
receiver is on and ready for use. The LED indicator will
blink on both the transmitter and the receiver when the
transmitter buttons are pressed.
The LED indicator color indicates the battery life level.
Green = Full charge
Amber = Medium charge
Red = Needs charge
If the unit is used while the LED indicator is red, it may
shut down automatically.
Receiver Indicator Light
When the Constant button on the transmitter is pushed,
the receiver indicator light will glow steadily (either
green, amber, or red based on the remaining battery
life), as long as you hold the button down, for up to
12 seconds. When the Nick button is pushed, the light
comes on for a fraction of a second.
7. LED Indicator

19
The Dogtra 3500X uses a lithium polymer battery.
Recharge the unit if the indicator light is red or does not
come on, the transmitter LCD shows only 1 bar on the
indicator, or the system will not stay on when any button
is pressed.
NOTE 1: Only use Dogtra-approved batteries, chargers,
and accessories for your Dogtra e-collars. This will
prevent any damage that can be incurred from
attempting to use a different charger.
NOTE 2: The unit has a partial charge when it leaves
the Dogtra facility. Upon receipt of the system, be sure
to give it a full 2-hour initial charge before the first use
away from any flammable substances.
NOTE 3: When a charger is not in use, disconnect it from
the power source. Fully charge the batteries if the unit
is to be stored without use for a period of 3 months or
more.
8. Charging the Battery

20
Follow the steps below to charge your system:
1. Open the rubber plugs on the battery charging
receptacles and plug in the charging cable.
2. Plug the charger into a 120-volt wall outlet or, if using
the auto charger, plug into a cigarette lighter only for
lithium polymer batteries (use a 220 volt European
charger for Europe). All indicator lights should glow
red when properly plugged in and the unit will
automatically shut off during the charging process.
You will need to turn the unit on again before use
once the unit is fully charged and unplugged from the
battery cable.
3. The lithium polymer battery is fully charged within
2 hours. The lights will stay red during the charging
process and turn green once the unit is fully charged.
4. After charging, cover the battery charging receptacles
with the rubber plugs.
