This operation involves the following: erase message memory, erase address book, reset SMS counters,
new presetting of default password.
To reset the SIM card proceed as follows:
- Cut off power supply
- Press the module key (S1)
- Power the device keeping the key pressed
- The module switches on
- After approximately 15 seconds, the red LED switches on with xed light (the key can be released)
- The red LED stays on for 2 about minutes. When it switches off, the operation is completed and the
message and address-book memory have been erased. The SMS counters have been reset and the
default password, which is 123456, has been restored.
- At this point, the module enters the normal operating mode.

The command signals are sent through a normal SMS message sent from a mobile phone to a number of
the SIM card placed in the CALL device. In its turn, for some commands, the device will reply with a SMS
message. The cost of these messages depends on the tariff and operator used.
The CALL device replies by default to the following:
- commands that require a reply:
status, numstatus, readbook, testtx, recstatus
- command messages:
modpsw, setrxpsw, resetrxpsw
- commands containing errors.
Moreover, the CALL device can send a SMS notice message also for the other command signals sent by
simply adding “?” before the command message.
The replies sent by the device vary according to the SMS sent and are described hereunder in the
description of command messages. The possible error replies, sent by the CALL device, change according
to the type of error made and are as follows:
POSSIBLE REPLIES OF ERROR:
“COMMAND MESSAGE NOT SET”
“PASSWORD NOT SET”
“COMMAND EXECUTION ERROR”
“COMMAND SYNTHAX ERROR”
“PASSWORD ERROR”
“ERRORE NON SUPPORTATO” ERROR NOT SET
“ERROR, MEMORY FULL”
“COMMAND UNKNOWN”
“PHONE NUMBER NOT PRESENT”
“ERROR, NO INTERNATIONAL DIALING CODE”
