Fig. 17. Assignment of alphanumeric characters to telephone keypad.
In order to send an SMS message:
1. Lift the receiver of the telephone connected to the telephone line output.
2. Dial the pager station number programmed in the module (see: "PAGER station tel. no."
p. 18), and then the telephone number to which the SMS message is to be sent. The
number should be dialed as soon as possible, without time gaps between the successive
digits (the country prefix should be entered depending on whether it has been
programmed by means of the "Prefix for SMS" function).
3. Two beeps will be generated by the module to acknowledge the number, if correctly
received. No acknowledgement or a busy signal mean a dialing error and the necessity to
restart the procedure (to make it easier, you can use the "Redial" key).
4. Enter the message according to the above described rules (the time of module waiting for
entering the next characters is not limited).
The SMS message sent from a landline telephone set can contain up to 62
alphanumeric characters.
Hanging-up when the text is being entered will terminate the SMS message sending
process.

command to start the module firmware update (the
"SMS initiating update” function,
"Firmware update" tab).
The module will establish connection to the firmware update server
whose address is programmed in the module.
