Remove the monitor from the hazardous area (at least
20 feet away from the manhole), disconnect the battery
pack, wait at least 1 minute, reconnect the battery pack,
and then attempt to communicate. If the monitor still will
not communicate, replace the 3.3-volt yellow fuse (when
replaceable) on the regulator.
