Important Safety Instructions
Warning – failure to follow these warnings and the usage instructions could result in
serious injury or death.
DO NOT use the static stimulus feature of the collar on dogs with an aggressive temperament.
This may cause them to inflict injuries to the dog owner or others. If you are unsure whether
this product is appropriate for your dog, please consult your veterinarian or certified trainer.
DO ensure that you comply with the fitting instructions in this manual for the collar. Skin
damage (such as redness or bed sores) may develop when a collar has been worn for too long

1. How does the DDOG® YARDMASTER 202S work?
The DDOG® YARDMASTER 202S Training Collar System offers a simple and effective way
for home users to train their dogs. By pairing a remote transmitter with a receiver collar, a
user can control the exact moment when a dog will receive a tone, vibration or static
response on the receiver collar. The level of intensity is adjustable for static stimulation (8
levels) and fixed for tone and vibration signals (1 level each). The end result is a training
system that allows users to teach basic obedience commands or thwart unwanted behaviors
using one or a mix of different signals that can be triggered at such time and at such level of
intensity as the users themselves determine as appropriate.

7. Using the YARDMASTER 202S for the First Time
When using the DDOG® YARDMASTER 202S Training Collar System for the first time, you
should make sure that the receiver collar has been properly paired with the remote
transmitter.
Test for proper pairing
1. To test whether the pairing between the two devices has been properly configured,
switch on the receiver collar by pressing the blue “On/Off” button at the front of the
collar.

2. Next, adjust the function dial on the remote transmitter to a position other than OFF and
press the toggle button (if required) until the LED light next to the number “1” is switched
on to indicate that the remote transmitter will operate at the transmission frequency of
the first paired receiver collar (which by default is the receiver collar that is shipped
alongside the remote transmitter).
3. Next, press the sound button on the remote transmitter and see whether the receiver
collar responds with an audible tone signal.
Press
If an audible tone signal is detected, it means that the two devices have been properly paired.
Otherwise, please go through the pairing instructions on page 11 to pair the receiver collar
with the remote transmitter.
8. Testing the Static Stimulus Function
A test light tool is included with the packaging box for the purpose of testing the static
stimulus function of the collar.
1. To begin testing, place the test light on top of the metal probes as shown below.

2. Then rotate the function dial to a level higher than 2 (otherwise the light emitted will be
too weak to notice) and press the static button on the remote transmitter to trigger a
static stimulus on the receiver collar. If the static stimulus function is working properly,
the test light will start flashing.
Press
9. Fitting and Powering On the Collar
The receiver collar should be fitted snuggly across the top of the dog’s neck (as opposed to
hanging it loosely at the bottom of the neck), yet loose enough to allow the user to slide one
finger inside the strap. The collar casing should be positioned at the front and center of the
neck and not rotated to either side. Both of the metal probes underneath the collar unit
should be in good contact with the skin as shown below. For dogs with thick coats, it may be
necessary to trim the hair underneath the collar unit to ensure that the probes are in good
contact with the skin. Once the collar unit has been fitted, trim down the excess strap to a
suitable length, if required.

The plastic collar strap can be removed and replaced with the spare nylon strap that comes
with the packaging. See page 13 for detailed instructions on how this is done.
Press the blue “On/Off” button at the front of the collar. If a solid green light stays on after
momentarily flashing in green and red color, it indicates that the collar is ready for use.
10.Sound/Tone Function
The sound button on the remote transmitter is the trigger for a tone signal on the receiver
collar. Each time the sound button is pressed, provided that the collar and the remote
transmitter are both switched on, a single tone signal will be generated. The collar is pre-set
with only one level of tone signal, so unless the function dial has been parked at the OFF
position, all other positions on the function dial will generate the same identical tone signal
when the sound button has been pressed. If the sound button has been held down, a
continuous stream of tone signals will be generated with a short time gap between each tone
signal.
Press
11. Vibration Function
The vibration button on the remote transmitter is the trigger for a vibration response on the
receiver collar. Each time the vibration button is pressed, provided that the collar and the
remote transmitter are both switched on, a single vibration response will be triggered. The
collar is pre-set with only one level of vibration response, so unless the function dial has been
parked at the OFF position, all other positions on the function dial will generate the same
identical vibration response when the vibration button has been pressed. If the vibration
button has been held down, a continuous stream of vibration responses will be generated
with a short time gap between each vibration response.

12. Static Stimulus Function
The static stimulus button on the remote transmitter is the trigger for a short static stimulus on
the receiver collar. The static stimulus is delivered to your dog via the metal prongs attached
to the receiver collar.
The strength of the static stimulus is adjustable and can be varied from level 1 to level 8 on
the function dial, but no static stimulus will be delivered if the function dial is in the OFF or No
Shock mode . The No Shock mode on the function dial is a safety mechanism designed
for users who only want to train their dogs using tone or vibration signals. Once the function
dial has been parked at the No Shock mode, no static stimulation will be delivered by the
receiver collar when the static button has been pressed.
Each time the static stimulus button is pressed, a single static pulse will be triggered that
lasts for a fraction of a second. If the static stimulus button has been held down, a
continuous stream of static pulses will be triggered. For safety reasons, the steam of static
pulses will be automatically cut off if the static stimulus button has been held down for more
than 10 seconds. The user will need to release the static stimulus button to reset the device
and press the button again to trigger another static stimulus response.

1. 2. 3.
To begin pairing a receiver collar with a remote transmitter, switch on the remote transmitter
and press the toggle button until the LED light for the collar number that you wish to
designate for the pairing has been switched on (e.g. if you want the receiver collar to be
paired as collar number one, then toggle the remote transmitter until the LED light for “1” is
switched on). Once the desired collar number has been selected, press and hold down onto
the toggle button until the collar number LED starts flashing. Next, with the receiver collar
already in the OFF mode, press and hold down onto the power button of the receiver collar
(i.e. turning it on) until you hear an audible tone. This will indicate that the pairing is
successful. The toggle button of the remote transmitter and the power button of the receiver
collar must be held down at the same time for the pairing to be successful.
To test whether or not the pairing is successful, try using the tone and vibration modes and
see whether the collar responds. If not, then please go through the pairing instructions again
to make sure all the steps have been followed.
14.Charging the receiver collar and the remote transmitter
The charging cable (see diagram below) that is shipped with the packaging box has three
end points: one draws power from the power adapter; one provides a charge to the receiver
collar and one provides a charge to the remote transmitter. The three end points allow the
receiver collar and the remote transmitter to draw a charge simultaneously.
(a) Remote Transmitter
If the indicator light on the remote transmitter starts flashing, it means that the battery of the
remote transmitter is running low and needs to be charged up. When charging the remote
transmitter, switch off its power and attach the cable end point that has a narrow body to the
Sound Activated Sensor
On/OffButton

13
charging pin at the side of the remote transmitter. The time to fully charge the remote
transmitter is approximately 1.5 - 2 hours, and the indicator light will turn into a solid green to
indicate that the battery is fully charged. The remote transmitter should remain operational
for approximately 2 to 3 weeks on a full charge (assuming frequent usage).
(b) Receiver Collar
If the indicator light on the receiver collar starts flashing, it means that the battery of the collar
unit is running low and needs to be charged up. When charging the collar unit, switch off its
power and attach the cable end point that has a fat hollow body and a metal spike at the top
to the charger port of the receiver collar. The hollow body of the cable end point needs to
envelope the left metal probe of the receiver collar while the small metal spike at the top of
the cable end point should be in contact with the charger port of the receiver collar, otherwise
the collar unit won’t receive a charge. The time to fully charge the collar unit is approximately
1.5 - 2 hours, and the indicator light will turn into a solid green to indicate that the battery is
fully charged. The collar unit should remain operational for approximately 1 week on a full
charge (assuming frequent usage).
15.Replacing the plastic collar strap with the spare nylon strap
A set of spare nylon straps is included with the box packaging that can be used to replace the
standard plastic straps that are fitted on the receiver collar by default. The instructions for
replacing the plastic straps of the receiver collar with the spare nylon straps are set out
below:
1 Use a screwdriver to remove the two screws on the backside of the main collar
casing that are used to secure the plastic straps to the main collar casing.
2 Locate the holes at both ends of the nylon straps. Place one nylon strap harness
(see diagram below) over the hole at one end of the nylon strap and line them up
on top of one of the screw holes (as mentioned in step 1) at the backside of the
main collar casing so that the hole of the harness, the hole at the end of the nylon
strap and the screw hole are all in alignment.
Make sure that the nylon strap harness is rotated to an angle that will allow it to be
properly fitted to the cavity space at the backside of the main collar casing where
the screw hole is situated.
3 Use a screwdriver to fix the harness and the nylon strap onto the main collar
casing using one of the screws that had been retrieved from step 1.
4 Repeat steps 2-3 on the other end of the nylon strap to fix it to the main collar
casing.
