Inserting the SIM card (only GM series)
To insert the SIM card in the modem, open the SIM card holder on the Mitsubishi Alarm Modem
by pressing the small button on the right of the holder with a pen or a pointed object.
You can now carefully pull out the card holder and insert your SIM card. Then push the SIM card
holder back into the modem until it snaps into position.
NOTES
If you are not using a new and unused SIM card, use a mobile phone to ensure first of all that
the SIM card does not contain any saved SMS messages (read or unread) as this may other-
wise cause malfunctions.
Avoid touching the contacts of the SIM card as electrostatic discharge may otherwise dam-
age it.
E
ATTENTION:
The SIM card should only be removed when the modem is in power-off state.
The SIM card may become unusable if this warning is not observed.
