NOTES
1) Audio signal will not be available in UCM-93/2.
2) If the UCM-93/2 has to be used with RTU-modules the PIN code must be disabled before use. Can be done with
a normal mobile GSM cellular phone or with a PC with a terminal program and the AT command AT+CPIN=XXXX.
Note also that the account must be ordered specially for supporting data at your provider.
3) IMPORTANT NOTE: The power supply MUST be capable of deliver the peak current required by the GSM modem,
otherwise you might have problems during power up or the communication will fail occasionally.
