sec.) at any time during the module switch-on. The two-minute counter will re-
set and start from the beginning.
Sending a request to log into the GSM network:
The icon in the upper left corner of the display indicates that the GSM module
has not yet acknowledged the request to log the module into the network.
Login to the GSM network:
If the radio part of the module is switched on, the display changes from "Star-
ting..." to "Registration...". The icon in the top left corner of the display also
changes and its new shape shows the GSM module switched on.
The time required to register the device to the GSM network depends on the
quality and intensity of the GSM field. Under good reception conditions, the mo-
dule registers to the network within 15 to 20 seconds. As the quality and inten-
sity of the GSM field deteriorates, this time increases and in extreme cases the
module will not register to the network even within one minute.
If this situation occurs, the GSM module is automatically switched off and a new
registration to the GSM network is attempted. The number of attempts is a con-
figurable parameter. If the last, usually the third, attempt to log in is unsuccess-
ful, the GSM module will remain switched off until the next request to log in to
the network (long press of the knob) or until the time preset for regular
transmission of measured data to the server.
Login to the GSM network:
After the device is logged into the GSM network, the display shows the name of
the operator and a numerical and graphical representation of the GSM field
strength at the antenna location. This intensity is expressed as a numerical value
from Q=1 to Q=31, with a higher number indicating a higher GSM field strength.
