How It Works
This remote training system is a safe and eective tool for correcting
dog's behavior, suitable for most dogs weighing over 6.8 kg (15 lbs).
The system communicates via wireless signals, allowing you to
guide your dog from a distance.
The system works in two ways:
1. Direct Remote Action: Pressing the Ultrasound or
Ultrasound+Strobe button activates features directly from the
remote.
2. Collar Response: Pressing the Sound, Vibration, or Static
Stimulation button on the remote transmits a signal to the collar,
activating the chosen feedback mode.
These cues help interrupt unwanted behavior and guide your dog to
follow commands.
Important Note: The maximum eective remote range of 300
meters is achieved under optimal, unobstructed conditions.
Obstacles, weather, and interference can reduce this range. For best
results, hold the remote horizontally away from your body. On the
other hand, ultrasound travels up to 7 meters only.

Troubleshooting
Q6: What is the lifespan of the batteries?
A: Under normal use, the lithium batteries support about 400 full
charge cycles. Actual lifespan depends on usage and charging
habits.
Q7: How long should a training session last?
A: We recommend short sessions of 10-15 minutes, 1-2 times per
day, combined with positive rewards for the best results.
Q8: Can I use a fast charger (9V/12V) to charge the devices?
A: No. Use only a standard 5V/1A (or 5V/0.5A) USB charger.
High-voltage chargers can damage the batteries and circuitry.
FCC Warning
This device complies with Part 15 of the FCC Rules. Operation is
subject to the following two conditions:
(1) This device may not cause harmful interference, and (2) this
device must accept any interference received, including interfer-
ence that may cause undesired operation.
NOTE 1: This equipment has been tested and found to comply with
the limits for a Class B digital device, pursuant to part 15 of the FCC
Rules. These limits are designed to provide reasonable protection
against harmful interference in a residential installation. This
equipment generates, uses and can radiate radio frequency energy
and, if not installed and used in accordance with the instructions,
may cause harmful interference to radio communications. However,
there is no guarantee that interference will not occur in a particular
installation. If this equipment does cause harmful interference to
radio or television reception, which can be determined by turning
the equipment o and on, the user is encouraged to try to correct
the interference by one or more of the following measures:
-Reorient or relocate the receiving antenna.
-Increase the separation between the equipment and receiver.
-Connect the equipment into an outlet on a circuit dierent from
that to which the receiver is connected.
-Consult the dealer or an experienced radio/TV technician for help.
NOTE 2: Any changes or modications to this unit not expressly
approved by the party responsible for compliance could void the
user's authority to operate the equipment.
The device has been evaluated to meet general RF exposure require-
ment. The device can be used in portable exposure condition
without restriction.
Frequently Asked Questions
Q1: Why did my remote and collar stop working suddenly?
A: First, check if both devices are powered on and not in sleep mode.
Second, check the battery levels and charge if low. If the issue
continues, re-pair the collar to the remote.
Q2: Will using the ultrasonic function of the remote aect other
animals?
A: Yes, it might aect other animals. While the ultrasonic mode
(emitting sound at 25 kHz) is designed for dogs, it may impact other
species (e.g. cats, rodents) within this frequency range.
Q3: Why is the ultrasonic function of the remote only suitable
for dogs aged 6 months to 8 years?
A: ● Puppies (<6 months): Auditory systems are underdeveloped;
ultrasonic exposure risks harm.
● Senior Dogs (>8 years): Age-related hearing loss may reduce
eectiveness.
● Eectiveness: Studies show success in 85–90% of dogs within the
recommended age range.
Q4: Does my dog need to wear the collar all the time after
training?
A: No. Once your dog learns the desired behavior, occasional use is
sucient to reinforce training. Continuous wear is not recommended.
Q5: Is the collar waterproof? Can my dog swim with it?
A: The collar is IPX6 waterproof, meaning it can withstand daily
splashing and spraying. However, it is not designed for submersion.
Do not allow your dog to swim or bathe while wearing the collar.
Training Guidelines
● Timing is Key: Correct your dog as they misbehaves, not after.
● Be Consistent: All family members should use the same
commands and correction methods to avoid confusing the dog.
● Gradual progression: Always begin with the lowest intensity
level and only increase if necessary.
● Mode selection: Prioritize Ultrasound or Sound modes rst. If
ineective, consider Vibration mode. Use static only as a last resort.
● Reward reinforcement: Immediately reward your dog with treats
or positive interaction (e.g. petting, praise) when it stops unwanted
behavior and responds correctly.
● Training duration: Limit focused training sessions to 10-15 minutes
at a time.
Daily Maintenance & Care
● Cleaning: Wipe the remote and collar with a soft, slightly damp
cloth. Ensure the collar's charging port seal is closed tightly.
● Battery care: If not used for a long time, recharge both devices
fully at least every 60 days to maintain battery health.
● Storage: Store in a cool, dry place away from direct sunlight and
extreme temperatures.

B.Charging the Collar:
1. Open the waterproof rubber seal on the side of the collar.
2. Connect the included Type-C cable to a 5V/1A power source.
Step 2: Power On & Pairing
1. Turn On the Collar: Briey press the collar’s power button " ".
The indicator will glow solid green for 2 seconds, then blink
intermittently, indicating it is on.
Notes:
1. Once paired, the devices will automatically reconnect when
turned on.
2. If pairing fails (timeout after 10 minutes), repeat Step 3-4.
3. For Multiple Dogs: Use the Channel button " " on the remote
to select an unused channel (DOG2, DOG3, or DOG4). Then repeat
the pairing steps for each additional collar.
Step 3: Fitting the Collar
1. Select and Install Contact Points:
The package includes long and short contact points.
● Long-haired dogs: Use long contact points.
● Short-haired dogs: Use short contact points.
Note: For very dense fur or to reduce friction, attach the included
silicone caps over the metal contact points.
Step 4: Begin Training
1. Basic Operation: Correct your dog at the exact moment of
misbehavior (e.g. barking, jumping) by pressing the appropriate
function button.
2. Recommended Usage Priority:
● Ultrasound: First choice for daily training. A high-frequency sound
(inaudible to humans) that interrupts behavior without physical
contact.
● Sound/Vibration: Use if ultrasound is ineective. Provides a
clearer, gentle reminder.
● Static Stimulation (Shock): Use only for emergency situations or
dangerous behaviors (e.g. chasing cars) when other modes fail.
ALWAYS start at the lowest level 1.
● Ultrasound+Strobe: Designed to deter external threats
(e.g. o-leash dogs approaching). Use to warn and distract.
3. Positive Reinforcement: Immediately after correction, reward
your dog with a treat or verbal praise (e.g. "Good dog!" with gentle
petting). This creates a positive association and improves training
eectiveness.
Testing the Static Stimulation Function
Use the included test light to ensure the function is working correctly
without testing on your dog.
1. Screw the contact points rmly onto the collar.
2. Press both metal probes of the test light against the two contact
points simultaneously.
3. Press the " " button on the remote. If the test light illuminates,
the function is working.
2. Adjust and Secure the Collar:
● Adjust the collar strap to t snugly around your dog's neck.
● After fastening, you should be able to t one nger comfortably
between the collar and your dog's neck (A).
● Position the contact points so they touch the skin on the underside
of the neck (B).
3. Check Comfort: Observe your dog for the rst 5-10 minutes. If
they scratch or paw at the collar excessively, readjust the tightness or
try dierent contact points.
