respond.

-volt (yellow) fuse on regulator may have blown.
Verify that the communication type is set to
Wireless
.
Connect directly with the monitor using a USB Serial
Interface cable (ADS p/n
8000-
0337). Verify the monitor
responds. If it does, the modem might be faulty. If it
does not, remove the monitor from the hazardous area
(at least 20 feet away from the manhole), disconnect
the battery pack, wait at least 1 minute, and then
reconnect
the monitor battery pack. If remote
communication resumes, try to connect several times to
ensure communication is reliable.
