Gateway is in std by mode
Gateway is in communication
There is a problem on the gateway
Power supply error. Check connection to the mains and connection
of the mains' adapter to the gate
The module is not logged in the network :
Defective SIM card (or the card is incorrectly inserted in its
compartment)
Obsolete 5V SIM card (the module supports cards for 3V and
lower voltage);
Logging in GSM with PIN has been set and the PIN has not
been set in the gate by the positioning routine;
GSM signal is too weak.
Unsuitable positioning of the aerial with respect to any of the
analogue telephone lines or an analogue telephone apparatus into
.
which GSM transmission is induced (identical as in case of a car
radio). It is necessary to test mutual position or totally relocate it.
Echo is automatically eliminated by electronic means in the gate. If
you hear a beep despite this measure, it could be caused by :
Too improper impedance adaptation of the BTS channel to
which either you or your counterpart are connected;
Mobile telephone, which you are calling (some older types,
some types of protective cases).
