6.2 Insert the SIM card holder inside the device
The DISCO-B4 device is equipped with a GSM modem. To use it, you must insert a
SIM card in the appropriate holder inside the device. There is no SIM card shipped
with the unit. The customers must provide their own SIM card for use. The unit has
altogether 12 screw holes. Because the SIM card must be inserted by the customers
only 2 screws are screwed on.
Attention
: The opening and closing of the housing must be performed by
qualified electricians.
The SIM card is obtained from your mobile provider and must be activated for GSM
data services before using it. Together with the SIM card, you receive a 4-digit PIN
number. Entering of the PIN allows your device to access the mobile network.
To insert the SIM card into the SIM card holder inside the device, follow the steps
below:
1)
Remove the power supply and any other connections from the device, then
place the device on the back. The housing has been screwed down by only 2
screws for quick opening and inserting the SIM card. These are located opposite
to each other on the housing ring. Unscrew these 2 screws
(1),
(2)
by using a Torx
T6 Screwdriver. In the delivered package there are also 10 other screws which
should be used to assemble the housing after inserting the SIM card.
2)
After unscrewing both screws, carefully open the housing cover
(3)
by using your
fingernails and then pull them apart using your finger. If you cannot open the
case with your fingernails, then use a flat non-metal object. The case has a black
rubber ring around the lower case of the housing which is advertised to make the
device whether proof. Improper handling of this rubber ring can lose the whether
proof capability of the the device housing.
Attention
: Do not remove any of the cable connectors inside the device case!
3) Locate the SIM card holder
