The d-mute no-bark collar is a safe and eective tool, which will help you to eliminate your
dog’s excessive or nuisance barking. The no-bark collar is a convenient solution in cases, when
your dog starts barking after a merest impulse, or keeps barking the whole day after you leave
to work, which can be annoying to your neighbours. The collar is activated by your dog’s vocal
cords vibrations only. This system prevents the risk that the collar would activate itself because
of other dogs’ barking. It is easy to adjust and set both the reaction of the collar to the vocal
cords vibrations and the stimulation intensity. There are ve modes of barking correction and
one mode for testing the device. You can choose from an audible beep tone, three levels of
stimulation and a special type of stimulation with growing intensity that has ve levels.
There are four models available that are suitable for dogs of all sizes. The models d-mute and
d-mute light are intended for medium-sized and large dogs, the models d-mute small and
d-mute small light are suitable for medium-sized and small dogs. No-bark collars have an
ergonomic and compact design are waterproof and very easy to use.

Battery insertion and replacement
1. Screw out 4 screws from the battery cover using a cross-head screwdriver and remove
the lid.
2. Insert a lithium battery CR2 3V into the battery compartment with a correct polarity
(according to the polarity indicated with the “+” symbol in the battery compartment).
Wrong polarity may damage the unit.When is the battery inserted correctly, the device
should make a sound.
3. Make sure that the rubber seal is clean and correctly seated in its groove.
4. Put the battery cover back and screw in the 4 screws adequately.
Checking the battery status
● When the battery is inserted the device is set into the standby or active mode.
● If the product begins to make a continuous beep tone, the battery is low. Insert a new
lithium battery CR2 3V in the device.
● If you are not using the device for longer period, take the battery out.
Choice of the contact points
The stimulation is transferred on your dog‘s skin through the steel contact points of the
electronic device. Each set contains 2 types of contact points with the at base, which
enable the vocal cords vibration transmission. Sucient length of the contact points has
to have a contact with the dog‘s skin, enabling the device to operate correctly. If you have
a short-haired dog use the 10 mm contact points, if you have a long-haired dog replace
them with the longer 17 mm contact points supplied in the kit. Screw the contact points
Device preparation

Fitting the collar
The device has to be positioned so that the contact points are placed on the neck where
the vocal cords are. The strap with the device must be tightened enough so that the con-
tact points are in contact with the skin of the dog. We recommend you to t the collar on
the standing dog.When you can t two ngers between the collar and your dog‘s neck, the
collar is tightened enough. We recommend to move the device up and down on the neck
to enable the contact points to get through the dogs hair onto the skin. If a dog has long or
thick hair, it is suitable to trim the hair in the area of the contact points.
TIP: When your dog has a dry skin in the area where the contact points are, it is good
to lubricate the dog‘s skin with a vaseline, hand cream, or baby oil - which enables a
correct transfer of stimulation impulses.
Warning: If the collar is too loose, the receiver is likely to move and repeating friction
can irritate the skin of your dog. Furthermore, in this case it is not ensured a reliable
contact of contact points with the skin and a proper function of the collar. We do not
recommend to leave the collar positioned at the same place for more than several
hours, because it could irritate the skin. If it is necessary to wear the collar for long
periods, change regularly the position on the neck of your dog. A collar with a receiver
that is overly tight, can cause pressure sores on the skin in the contact area of the
contact points. If this happens, do not use the training collar until all traces of irritation
are gone.
onto the screws of the device - see the picture Receiver in the chapter Product description,
page 7. Tighten them manually carefully (do not use a pliers – this could damage the
product).

d-mute is activated automatically when the dog starts barking (sometimes even with
howling and growling). The collar does not operate on the principle of sound, but it
responds to vibrations of the vocal cords. This system thus prevents the risk of a false start
caused by another dog barking.
● Device with inserted batteries is in standby or active mode. (The device can be turned
o only by removing the battery.)
● In standby mode, the device is waiting for a dogs bark - vibration of the vocal cords.
● First bark activates the device and it emits an acoustic beep tone or beep tone with the
stimulation impulse. Intensity of stimulation depends on the selected mode.
● The collar has 5 modes for barking correction. You can choose between an acoustic
beep tone, three levels of stimulation pulses and pacing mode with increasing intensity
in ve steps see table on page 12.
● If your dog keeps barking, the device will beep or will beep together with stimulation
impulse. Collar beeps 4times and then the process stops automatically.
● When the dog gets quiet for 10-20 seconds, the system will switch back into standby
mode. Another barking will be accompanied by an acoustic beep signal or the acoustic
signal with stimulation impulse.
● Once the dog gets used to the collar and how it works, then he will stop barking after
the acoustic signal. When this happens it is possible to switch to the mode 1 (if the dog
starts barking again, short change of the mode will remind him of collar function).
The basics of use

11
The collar is preset to factory default to mode ”1“ – correction with acoustic beep tone
only.
Correction modes can be set to the acoustic beep tone only or acoustic beep tone with
dierent levels of stimulation impulse. We recommend to start the training with the collar
set to the beep tone with no stimulation impulse. This way, the dog can realize the
connection between the device and its barking. The beep tone may not be enough for
the dog to stop him barking at rst, but it may help him to understand that it comes
straight after his barking.
When you are happy with the dogs response to the collar, you can set it according the
table of correction modes on next page. The correction mode can be set according to
your needs.

*The choosen mode can be found out by number of beeps, when you put the magnet
shortly to the target on the device (see pic. on page 11). To change the mode put the
magnet to the target for longer period and wait until you hear desired number of beeps
(1 - 6).
* * The 5th mode with ve increasing levels essentially replicates the functionality of
previous modes. After activation follows an acoustic beep tone and low stimulation
impulse in the event that the dog is not deterred and still barks, it is followed by another
and higher stimulation impulse, so the process is repeated until the highest pacing
impulse. By the 5th impulse this mode ends, even if the dog is still barking, for security
reasons impulses stop for 15 seconds and then it re-enters standby mode. Upon further
activation is the process repeated again from the lowest impulse, when the dog stops
barking, collar goes into standby mode.
Attention: 4th and 5th stimulation impulse at the 5th mode is stronger than in mode
4 (high).

13
*** Operation test is a mode, which is used to verify proper operation of sound and
stimulation impulse. Connect each wire of the test discharge lamp to the one contact point
(loosen the contact points, put the wires under the lamp outlets and tighten again). When
selecting the mode, no. 6 (operation test) you should hear the acoustic signal + electro-
nic impulse comes ON (test lamp lights up), then the software switches itself to a mode 1
(acoustic beep tone). If you don´t hear a long acoustic signal or if it does not light up send
to the service.
Setting reaction to vibration (vibration detection sensitivity) with a trimmer
The reaction to the vibration means that the device is activated by vibrations of the dogs
vocal cords. If your device only reacts to a signicant or contrariwise on bland vibration of
vocal cords, which are scanned by the contact points, you can adjust the sensitivity of the
collar so it starts working only at the right moment. This (sensitivity) setting is important
for the proper function of the device.

Using the ne adjustment trimmer, you can decrease or increase the sensitivity of the
collar to vocal cords vibrations (see pic. on page 13). It is set to a medium value by factory
default. By turning the trimmer anti-clockwise, the sensitivity is decreased and by turning
it clockwise, it is increased.
Attention: trimmer is prone to tearing down!
● This electronic device d–mute is waterproof only on condition of the good state of the
seal.
● Do not allow water into the device if it is open.
● We recommend you to replace the rubber seal, which is placed under the cover of the
battery compartment of the transmitter and the receiver, once a year.
● If the device is not used for a longer time, take out the batteries from the battery
compartment.
● Do not leave old battery in the device, it can damage the device.
● Before xing the collar check that the contact points are tight.
● Do not leave the collar on the neck longer than 12 hours a day.
Using the d-mute in winter
When using d-mute in winter, please keep in mind:
● Low humidity – causes less skin conductivity. It is necessary to provide better
conductivity between the contact points of the receiver and the dog‘s skin. This can be
achieved by lubricating the dog’s skin in the touching points of the contact points with
vaseline, baby oil, hand lotion, etc.
For the best results

15
● Thicker fur dog – it is necessary to tighten the collar so that the permanent contact
with the dog‘s skin is ensured. If the fur is too thick, it is recommended to cut the hair
or choose a longer type of contact points.
● Battery properties change – temperatures below 0 °C slow down chemical reactions
in batteries. To ensure a performance of repetitive stimulation impulses (especially of
higher levels), it is recommended to insert a new battery into the receiver for the
winter time. During the training, observe continuously dog‘s reactions and increase the
stimulation level as needed.
1. Read again this user guide and make sure the problem is not caused by a at battery
or incorrect use.
2. Make sure the batteries are inserted with the correct polarity.
3. If it seems, that the dog does not respond to the stimulation impulse:
 ● Check again, if the battery is not low.
 ● Test the device´s function with the test discharge lamp. (See the Operation test on
the page 13).
 ● Check whether you have choosen correct length of the contact points (See the
chapter: Choice of the contact points) and ensure contact points are well tightened
(see the chapter: Fitting the collar).
 ● If the dog has dry skin, moisten the skin.
4. Check the correct function of the stimulation impulse. By using the test discharge
lamp you can easily check correct function of the stimulaiton impulse. Follow the
instructions on the page 13.
5. If the problem still persists, contact your dealer.
Troubleshooting

16
It is important to keep the device clean. Never use volatile substances eg.: thinner,
gasoline or other cleaners. To clean your Dogtrace d-control use a soft, damp cloth and, if
necessary, neutral detergent.
d-mute is waterproof only on condition of the good state of the seal. We recommend
you to replace the rubber seal, which is placed under the cover of the battery
compartment of the transmitter and the receiver, once a year. Clean the rubber seal
and make sure that the rubber seal is correctly seated in its groove every time you change
the batteries; tighten the screws using adequate power.
If the device is not used for a longer time, take out the batteries from the battery
