5 Installation guide
5.1 Mounting and putting into operation
Disable PIN code request, voicemail
and “notification on missed calls”
services on the SIM card placed into the module.
Enable caller identification and caller ID sending services on the SIM card at
the GSM service provider
(a few types of SIM cards do not have these services
enabled by default).
Inserting the SIM card:
Unscrew the four screws on the back of the module using an appropriate
screwdriver. When unscrewing, hold the front cover and back cover together so as
not to fall apart, as this may damage the connecting cables.
Take apart carefully the front cover from the back cover. Take care not to strain the
connecting cables. The circuit board is fixed to the back cover.
The SIM card should be inserted in the SIM slot found on the middle of the circuit
board, near the display unit:
1. pull back (away from the display unit) the metal security lock of the SIM slot until
it clicks
2. reach under the metal security lock with your fingernail and open the slot
3. slide the SIM card into the opened part with the contacts facing down, as shown
in the figure above
Close back the opened part together with the SIM card
Press down carefully and pull forward (towards the display unit) the metal security
lock, until it clicks
Assemble the front and back cover so that the connecting cables (except the
flexible flat cable) should not lay under the spe
aker’s magnet
Hold the front and back cover together and screw back the four screws, but do not
overtighten them.
Test the GSM signal strength with your mobile phone. It may happen that the signal
strength is not sufficient in the desired mounting place. In this case the planned
installation place can be changed before mounting the device.
Do not mount the unit in places where it can be affected by strong electromagnetic
disturbances (e.g. in the vicinity of electric motors, etc.).
Do not mount the unit in wet places or places with high degree of humidity.
For appropriate RF range, the device should be mounted horizontally in
upright position, on the wall or other suitable surface, at least at 1 meter from
the ground level.
Avoid mounting the device in the close proximity of metal surfaces, because
these greatly reduce the RF transmitter’s operating range!
