Charging & Power
How do I charge the device properly?
Use a standard 5V charger (not a fast charger). The light turns red while charging and green when fully charged.
How long should I charge before first use?
Charge for about 4 hours before your first use to ensure full battery performance.
Why doesn’t it work while charging?
All functions stop automatically during charging. Unplug the cable before use.
How do I know if the battery is low?
If the device seems less effective or the light indicator is dim, it’s time to recharge.
Can I overcharge the device?
No worries — it has built-in overcharge protection. Still, unplug it once the indicator turns green to extend battery life.
Operation & Usage
The device doesn’t seem to work — what should I do?
1.Check the power level.
2.Make sure there are no obstacles.
3.Try switching the waveform mode.
4.Fully recharge and test again.
5.Some dogs with hearing loss may not respond.
Can it operate continuously?
No. The device works for up to 10 seconds per press. Press again to reactivate.
Can I use it while it’s raining?
No. The device is not waterproof, so avoid exposure to rain or moisture.
Does it work through walls or windows?
No. Ultrasonic waves cannot penetrate walls, glass, or thick objects. It works best in open spaces.
How should I aim it for best results?
Point the device directly toward the dog’s direction, keeping a clear line of sight for maximum effectiveness.
Technology & Safety
How does the ultrasonic repeller work?
It emits high-frequency sound waves (20,000–45,000Hz) using an imported M6 transmitter, which irritates dogs without harming them.
Is ultrasonic sound safe for humans and pets?
Yes. It’s completely safe for humans and other pets like cats, as the energy level is very low.
What’s the difference between Linear and Curved waves?
·Linear wave: Travels farther in open areas.
·Curved wave: Reflects and concentrates energy in smaller areas.
Choose based on your environment.
What’s the effective range?
Up to 25–30 feet (8–10 meters) in open space, depending on the dog’s sensitivity and surrounding environment.
Can it be used as a training tool?
Yes, it can be used to correct unwanted behaviors like barking or approaching aggressively, but should not replace proper dog training.
Light & Control Features
How do I turn on the flashlight?
Press the flashlight button once to activate. Press again to turn it off.
Why isn’t the strobe light working?
The high-frequency strobe light only activates in Linear Wave mode.
Can I use the flashlight and ultrasonic function together?
Yes, both functions can be used simultaneously for better deterrence.
What is the purpose of the strobe light?
It provides a visual deterrent that works together with ultrasonic waves, especially effective in dark environments.
Does the light drain the battery faster?
Yes, continuous flashlight or strobe use will consume more power. Turn off when not needed.
Effectiveness & Maintenance
Does it work on all types of dogs?
It’s effective on most dogs regardless of size or breed, except for some with hearing impairments.
What can affect performance?
Battery level, obstacles, ambient noise, and dog distance can all impact effectiveness.
Is it harmful to dogs?
No. It only creates temporary discomfort without causing any physical harm.
How should I store the device?
Keep it in a cool, dry place, away from direct sunlight or moisture.
How long does the device last?
With proper use and care, the device can last for 2–3 years or longer, depending on frequency of use.
