Using the SIM card
Before using the SIM card, we recommend that you test it in a mobile
phone to see if it’s working.
Particularly:
- Check that no PIN code has been set. If so, exclude it.
- Check the remaining credit
- Send a SMS message and check if it arrives.
Switching on
censione
After switching the device on, SMS messages not yet delivered or
sent during the first instants of operation will be cancelled without
being performed.
Standby
In Standby status, CT3MA is recorded in the GSM network and it is
ready to send and to receive SMS messages.
Synchronisation with the GSM network is obtained through short and
continuous transmissions.
CT3MA consumption in this status depends on whether the network
is avai-lable or not.
Sending an alarm
When input contacts are closed, the corresponding LEDs (G and H)
will turn on and CT3MA will send to stored numbers the following
message: “Input1 ON!” or “Input2 ON!”.
Alarm sending condition can however be set as follows:
Send alarm at contact closing
Send alarm at contact opening
Send alarm at both contact opening and closing
NOTE: Alarm is only sent if there is at least one mobile phone num-
ber stored, to which the alarm message can be sent. To cancel a
stored phone number, to customize the alarm message or to select
the alarm sending condition, follow the procedure described in para-
graph “ Alarm commands” on page 22.
