8. SIM Card*
A Mini-SIM card must be inserted in the Series ULTM to allow use of the cellular
feature. Never insert or take out a SIM card when Series ULTM power is on. Follow
these instructions regarding your SIM card:
8.1 The SIM card must support SMS services with your local cellular operator. You
do not need any voice or browser capabilities in your cellular service.
Depending on your cellular operator – you might be required to use a USIM
card.
8.2 Deactivate the SIM PIN code if the PIN code is active before inserting in the
ULTM. Deactivation is preformed by inserting the SIM card into a cellular phone
and following the instructions of the phone manufacturer. PIN code
configuration is usually found in your phone Settings – Security Settings – PIN
Code Request or similar.
8.3 Always test your SIM card before inserting into Series ULTM. Test the SIM card
by inserting the card into a cellular phone and sending an SMS. Verify that no
PIN code is required, that the proper operator serves the cellular link and that
the SMS reaches its destination.
8.4 Turn off Series ULTM. Turn the Series ULTM top cap counter-clockwise and
expose the electrical connections board. Insert the SIM card into the proper slot
as described in the following figure. The SIM may be pulled out by pressing it
downward again. Insert as shown in Figure 9 below.
8.5 Aim Series ULTM to proper target (e.g. floor), turn on Series ULTM and closely
observe the lower status line on the display (status lines are explained in the
Operating Instructions Chapter 3- Measurement Screen sub-chapter).
You should observe the report “GSM Initializing” for 30 to 60 seconds. Then you
should observe several additional status reports including “GSM Active”. This
indicates proper SIM card operation.
*Series ULTM only supports AT&T and T-Mobile mini-SIM cards. Make sure unit will
work with carrier.
