## Questions & Answers

**Q: Is this compatible with the Pawz Away collars?**
A: Per Petsafe  they operate at 18 khz radio frequencies. So if your Pawz away is 18 khz than it will work. They state all Petsafes are compatible.

**Q: why doesn't this work?**
A: If both lights are out, there is no power to the unit.   If you are sure that you have power to the unit, it may be defective & needs replacement.
If the "Loop" light is out, there is a break in the under-ground  boundary wire.  This is more difficult top find, but if you walk-it, you might find where an animal has dug it up.  

Hop this helps..

**Q: will this work with my RFA-561 collaes?**

## Customer Reviews

### ⭐⭐⭐⭐⭐ Works well but
*by A***R on August 19, 2024*

This is my third one. The others went bad over year or two. Called service several time and finally figured out it was set up too close to electric box and heavy metal objects. So just install it away from everything possible!!!

### ⭐⭐⭐⭐⭐ Petsafe is perfect for 4 dogs
*by S***H on September 1, 2024*

The system works perfectly with my existing system. The dogs are safe and contained to my yard & away from the road.

### ⭐⭐⭐⭐⭐ Our cat loves it.
*by S***E on December 17, 2023*

Our existing system started to alarm. Usually this is when the line/wire breaks. I replaced the entire loop and it still was alarming. I replaced the main unit with this model, and it's working fine again. Just an FYI that these transmitters don't last forever. Ours was 4 years old.
