Once the transmitter is switched on, it generates a signal from this wire. This activates the dog's receiver whenever the dog comes close to the boundary wire. The transmitter is a rugged design. It is resistant to damage from external elements such as moisture, insects, lightning and hailstones. It incorporates a visual and audio indicator to show that the boundary wire is activated properly.
Power is provided by an in-built solar panel.
No external power connection is needed. Simplicity and Reliability A solar powered transmitter is installed outside where it is needed and is therefore very quick to install. This is a favourable point when compared with mains powered transmitters that must be located indoors. These require extra installation time cutting holes in walls or window frames in order to connect the boundary wire to the mains powered transmitter. Another problem with mains powered transmitters are they will likely cease to operate during a power failure.
