Installation/De-installation
4.1
Inserting a SIM-card
Insert a SIM-card in the communication unit as follows:
1.
If present, remove a previously installed SIM-card by releasing it
(pushing it in) and withdrawing it.
2.
Insert the SIM-card into the slot as shown below and gently push it in
until it engages. Once the SIM-card is properly inserted, it should not
extend beyond the side of the device.

Correct insertion of the SIM-card
Keep SIM-card contacts clean
SIM-cards have electrical contacts that may come into contact with the user
during normal use. The presence of oils and dirt on these contacts may
cause corrosion on these contacts that are not apparent during the instal-
lation or shortly thereafter. Such corrosion may cause the contacts to
become unreliable and affect the option of the communication unit. It is
recommended that the user clean the contacts with a suitable solution or
perform the installation in a controlled clean environment to maximize the
operating life of the modem.
SIM with roaming disabled
It is possible to get SIM cards from Mobile Network Operators where
roaming is disabled. This is recommended in order to avoid higher service
charges when installing meters near the border of countries. There are
initialization commands that can also be added to the CU that can cause
the CU to select a pre-defined operator. This is the less preferred solution
and may cause GSM LED behaviour to change.
4.2
Fitting in meter
No voltage to meter when fitting
In order to avoid hazardous electric shocks, ensure there is no voltage
applied to the meter when fitting the communication unit. Contact with live
parts is dangerous to life. Disconnect the meter from the power supply as
described in the meter user manual.
