If the Remote is in an “Alarm” state, the unit may still be operational and
associated. Look for the association state in the Wireless Network Status
screen to determine if the unit is associated. If it is, then look at the Error
Log for possible clues.
If the unit is in an “Alarm” state and not able to associate with an Access
Point unit, then there may be problem with the wireless network layer.
Call in a radio technician to deal with wireless issues. Refer the techni-
cian to the RADIO MEASUREMENTS on Page 91 for information on
antenna system checks.

This screen provides detailed information on data exchanges between
the unit being viewed and the network through the wireless and the
Ethernet (data) layers. These include:
The most significant fields are the Packets Dropped, Retries, Retry
Errors, Receive Errors and Lost Carrier Detected. If the data values are
more than 10% of their sent and received counterparts, or the Lost Car-
rier Detected value is greater than a few dozen, there may be trouble
with radio-frequency interference or a radio link of marginal strength.
