errors you see. See below for troubleshooting tips. If you are
successful, please reattach the PCB into the Em50G case.

Troubleshooting

Use this quick guide to troubleshoot cellular connection issues with
the Em50G logger. Performing these steps before contacting Decagon
or your cellular carrier will result in the quickest possible resolution
of the problem.
Consider the simple causes first. Is the Em50G antenna connected?
Is the logger installed where there is cellular service? Did you con-
figure the APN setting correctly?
Use the Communication Test feature of ECH2O Utility (in the Ac-
tion menu) to test the cellular connection at the location where the
Em50G is deployed. Important messages appear in the "Test Sta-
tus:" field above the progress bar. Carefully note the error message
and match with the messages below. Always perform the Em50G
Communication Test several times to make sure the error (or suc-
cess) is not intermittent. It is normal for the Em50G to take longer
to connect to the cellular network when it is first used in a new area.
"SIM failed (with error code)" go to issue 1
"GPRS network registration timeout error" go to issue 2
"GPRS network registration denied or failed" go to issue 2
"failed to start internet connection" go to issue 3
Issue 1. The SIM card in the Em50G enables cellular communica-
tions. A SIM failed error indicates the SIM is not operating correctly
or is not inserted in the logger correctly. If the SIM is installed cor-
rectly, contact your cellular provider for suggestions.
Issue 2. GPRS network registration errors indicate the Em50G
is not able to connect to the local cellular network. The reason for
this failure could be as simple as there is no cellular coverage at the
install location. Try the following troubleshooting steps:
