Error code GSM or modem:
Red LED flashes n times? This implies an ERROR:
1 x = Internal modem does not respond.
2 x = No SIM card detected inside the modem.
3 x = PIN invalid (PUK entry necessary, therefore insert
the SIM card into a mobile phone).
4 x = Credit is empty.
5 x = No / Bad reception (additional antenna?).
6 x = SIM card is not registered / activated.
7 x = Other modem error.
Registration was not successful, if necessary try to reset.
8 x = Interlock active!
In case of lots of failed network dial-up trials the device will
retry the dial-up only once a day. This mode operates for
255 days. By pushing the [Enter] button the device does
one logon trial to mobile network again. In case of success-
fully sending an SMS the interlock is removed.
9 x = No destination mobile number has been set up.
#T command has not been sent or OilView connection has
not yet been linked.
Device is not sending.
Probably internal interlock is active!

Query device via smartphone: Send #r as SMS to the device
and wait for device replying (3 Min.).
