Operating the GSM Modem
7.4.3
PIN OK, no network, MAM not logged in
The MAM cannot be logged in if there is no network reception available for the provider con-
cerned, even if the PIN that has been entered in the project for the inserted SIM card is correct.
The Line LED will not flash and will remain off.
The Line LED will flash again, if the reception quality is sufficient, by using a stronger antenna for
example.
7.4.4
PIN incorrect, MAM not logged in
If the PIN that has been entered in the project for the inserted SIM is incorrect, the MAM will not
be able to log in, and will indicate this by causing the Process, Line and Mail-out LEDs to flash.
The same will happen if after initial commissioning or after a factory reset no project and there-
fore no PIN is loaded onto the MAM.
Ensure that a valid SIM card was inserted, that it is seated correctly and the PIN used is correct.
7.4.5
SIM Card disabled, entry of the SUPER PIN
If the PIN was entered incorrectly 3x,the SIM card will be disabled. The card can be unlocked
again by entering the SUPER PIN. To do this, insert the disabled SIM card into a mobile phone
and enter the SUPER PIN and PIN as described in the operating instructions. Once the mobile
phone has logged in properly with the SIM card, the unlocked SIM card can then be reinserted in
the Mitsubishi Alarm Modem.
7.4.6
SIM Card Service Center
Additionally, use a mobile phone to check if the SMSC (Short Message Service Center) number
ist stored on the SIM card. If not so, sending SMS from the Mitsubishi Alarm Modem will not be
possible. In that case, contact your mobile service provider for details on how to store this num-
ber on the SIM card.
7.4.7
Caution in Border Regions: Logging in abroad
Like a mobile phone, the MAM also searches for the strongest mobile network provider in the
area. In areas up to 10 kilometers from international borders, this may be a foreign mobile phone
provider. Considerably higher costs may be incurred if the MAM logs into one of these (roam-
ing). Moreover, problems may also occur with the sending of SMS messages and e-mails. You
can prevent the logging into "foreign" networks by allocating a "home network" to the SIM card.
