All text messages sent to the CX36 are considered valid and executed only if they start with the correct 4-digit pass-
word. The device return the invalid received SMS to the phone user number 1 (User1). This is convenient for receiv-
ing SMS messages sent by the operator relating to the lapse of the SIM and the related tax credit. The Echo func-

For example: if we send the CX36 an SMS with the text ABCDE, User1 will receive the following SMS: SMS ECHO:
ABCDE. If the Echo function is disabled, by sending an SMS with invalid password, the CX36 does not send SMS
but the green LED flashes 3 times outside.
