h ow do you use with asphalt entrance?

The probe is shallow buried parallel and just off the edge of the asphalt, with the cable running also shallow underground out to a nearby tree upon which the transmitter box is hung.

Do you HAVE to bury the cable also all the way to wherever you hang the transmitter?

I have found the sensor to be particularly sensitive to voltage gradients from lightning strikes even a few miles away. The gradients are near the surface, so there are less false trips with the wire buried even a few inches. Bury the wire, and don't use any more than you need to. Cut off the excess and try to keep the wire short.

Can one dcpt-4000 transmit to 2 4k plus receivers?

Yes. We keep one in our house and one much further away in our shop.

I presume the sensor is battery operated? it says 4 cr 123, how long does the battery last? does it signal when getting low?

YMMV. The batteries can last 1-3 years depending on how many times the sensor was triggered. If you hear a second alert 30 seconds after the first alert, and nothing has activated the transmitter again, the batteries in the transmitter box are low and should be replaced.
