returns multiple successes.
Note: The cellular radio is on while the Em50G Cellular Test di-
alog window is open. Be sure to close the window when you are done
testing to preserve battery power.
If the Em50G Cellular connection quality is poor, try moving your
logger a short distance to improve the signal strength. Also, consider
elevating the antenna by elevating the logger or using an antenna
extension cable to improve signal strength. In some cases it is nec-
essary to use directional antennas to obtain a sufficient cellular sig-
nal. Please contact Decagon or your Decagon representative for help
choosing the correct antenna for cellular frequencies at your location.
The Communication Test is checking both the cellular signal strength
and the connection to the Decagon Data Service. If the Data Service
is temporarily unavailable due to Internet problems, the connection
quality reports a failure even if you have strong cellular signal. If your
cellular signal strength is good (above '12'), then it is reasonable to
expect good connection quality once the Em50G can re-connect to
the Decagon Data Service.
Note: The measurement data collected by your Em50G is automati-
cally queued for the next successful connection to the Decagon Data
Service. Short term cellular or Internet outages do not impact the
integrity and continuity of your data.

Like all Em50 loggers, the Em50G stores more than 36,800 sensor
readings for each of the five sensor ports. You can use any ECH O
system software to directly connect to the logger for data down-
load. Your data are always safely stored in non-volatile memory as
