Q: "Are the pet chime paws (transmitters) weatherproof and hence suitable for outside use?"
Answer: According to Koolatron, the manufacturer, the paw is essentially weatherproof/water resistant.
- The paw shelters the electronic components.
- Seal the paw in a baggie placing it where it may be flooded or doused by torrential rains.
- Or mount the paw outdoors on a wall or under a protective overhang.
- Use an additional paw for the dog to signal that it wants to go outside.
