Troubleshooting
Possible sources of problems with the SePem 01 GSM are:
Fault with the
GSM Logger
Quality of the network connection
The quality of the network connection may vary considerably. For
example, this can be affected by the weather and parked cars. In
practice, this means that a network connection may suddenly be
lost, even if it has previously been verified using a test SMS.
SEWERIN Service will be pleased to provide assistance in cases
where the tips in the following chapters do not help in identifying
the cause of a fault (Tel.: +49 5241 934-250).
