To load the SIM card: 
1.  Locate the SIM card slot on the right hand side panel 
2.  Slide the plastic locking tab to the left, if required, to expose the full width of the slot 
3.  Position the SIM card so the edge with the diagonally cut corner is facing inward and the gold contacts are 
facing up. Slide the SIM into the slot until it clicks into place 
4.  Slide the locking tab to the right to lock the SIM in place. The SIM will not be recognised unless this is done. 
To remove the SIM card: 
1.  Slide the locking tab to the left 
2.  Press the SIM in slightly (you may need a fingernail or small screwdriver), until it pops out. 
Warning: Be sure that you are aware of the risks and restrictions for operating a radio transmitting device such as the DT80 modem. 
See 
Safety Information (P414) for more details. 
Configuring the Integrated Modem 
Automatic Configuration 
By default, the DT80 will attempt to automatically configure the following settings: 
•  Access point name (APN), and account name/password if required 
•  Email (SMTP) server name, and account name/password if required 
The DT80 auto-configuration feature works by looking up pre-defined settings based on the mobile carrier that issued the 
SIM. Be aware that automatic configuration might not be possible if: 
•  the DT80 does not recognise the mobile carrier that issued the SIM card. In this case fixed default settings will 
be used. Internet access will not
 be available, because no valid APN will have been set; you will need to 
configure this manually, as discussed below 
•  the carrier is recognised, but the SIM is not set up to use the "standard" plan from that carrier. Internet access 
may
 be available but some features might not be available. For example, the actual SIM plan might not include 
access to an SMTP server, in which case the SMTP server will need to be reconfigured to use a third party 
email provider 
Manual Configuration 
In order to manually configure the integrated modem, it will be necessary to connect to the DT80 using an alternative 
communications medium, e.g. Ethernet or USB. You can then either: 
•  directly enter the profile commands described here, or 
•  use the dEX Configuration Builder to generate a configuration that contains the required commands, then save 
it to the logger 
In dEX, most of the required modem configuration is done on the Modem page. To reach this page, click on the logger 
model name at the top left, then select Modem from the list of categories. See Figure 83.
