Frequently asked questions

How does the Rader positioning technology function?

Radar, also known as "radio positioning," is fundamental in most radar systems for distance measurement. PetHey F900 wireless dog fence utilizes the latest radar technology to create a fence boundary centered around the transmitter. Once set up, pets can roam freely within this fenced area. If your pet crosses the boundary, the receiver collar emits a warning to remind them to return. This system eliminates the need for a physical fence, SIM card, or monthly fees, making life easier for you and giving your dog more freedom.

Is static stimulation safe to use?

Static stimulation is very safe, with intensity similar to a mild static shock, posing no harm to pets. If you or your pet are sensitive to static stimulation, you can opt for the vibration mode, which does not include static warnings.

What are the differences between test mode and working mode?

Test mode is primarily for checking signal stability and does not set up a fence boundary. During testing, the pet collar will only alert if the signal is lost. Before regular use, switch to working mode and set the fence boundary.

How accurate is the distance displayed on the main unit?

The main unit displays the straight-line distance, which may have a slight margin of error. Use test mode to accurately determine fence boundaries.

Do dogs need special training to use the fence feature?

Yes, appropriate training is required for dogs before using the fence mode. Detailed training guidance can be found in the training manual we provide.

Can this product be used with other animals such as cats, cows, or sheep?

This product is specifically designed for dogs due to their intelligence and adaptability. It is not recommended for use with cats or other livestock, as their behaviors and reactions may differ significantly from those of dogs.

What is the charging duration for the device?

Using a 5V2A charger, it takes about 6-7 hours to fully charge the main unit and 3-4 hours for the collar. It's recommended to charge when the battery is low to maintain battery life.

What is the operational duration of the device after being fully charged?

The duration of use depends on the frequency and mode of operation. For example, with continuous use of the fence test mode, the main unit can last for approximately 67 hours, while the collar can last for about 24 hours.

How many dogs can be simultaneously controlled with this system?

This product can control up to three dogs simultaneously. Additional collar receivers need to be purchased separately.

How waterproof is the product?

The collar receiver is waterproof, but the main control unit is not. Please keep the main unit away from water.

For what sizes of dogs is this product appropriate?

This product is suitable for medium to large breeds of dogs.

Mike Johnson
easy and straightforward

Setting up the F900 was incredibly easy and straightforward. Within just a couple of minutes, we had everything configured and were good to go. The clear and concise instructions made the installation process hassle-free. Our smart dog quickly learned to respect the boundaries set by the F900 within one week. This has significantly eased our worries, knowing that he stays within the safe zones we designated for him. This device has truly made a positive impact on our daily lives.

JJ White
Good Hiking Companion

The F900 is super portable and perfect for outdoor use. I often take my dogs on hikes, and this device makes it easy to keep them contained in a manageable area when we need to take a break. The battery life is impressive, lasting through several outings without needing a recharge. It's an excellent solution for any pet owner who enjoys outdoor activities and needs a reliable, long-lasting containment system.

Andrew S
Suitable for medium+ large dogs

I have been using the F900 for a few months now, and it works wonderfully for my dogs. But I have three large dogs and one small dog. The device supports all three large dogs with no issues, offering great features and reliability. The only downside is that it's not ideally suited for my small one, as the collar might be a bit bulky for it. However, for my large dogs, it has been perfect in every aspect.

Jason Scott
Worry-Free fence

What I absolutely love about the F900 is how incredibly hassle-free it is—no wires or SIM cards needed at all! Setting it up was a breeze, and we were up and running in no time. Our dog, Luna, took to it so quickly. Within just a few days, she understood her boundaries perfectly. Now, we can let her roam the yard without constantly worrying about her sneaking out. It's such a relief to have that peace of mind, knowing she's safe and secure. The whole process was seamless, and Luna is happier and more confident with her newfound freedom. For anyone looking for an easy and effective way to keep their dog safe, the F900 is a good solution.

Riley Clark
No need complicated setup

I love the simplicity of the F900. No need for complicated installations or subscriptions. Our dog, Molly, learned the boundaries quickly, and we've had no problems at all.
