2. LIMITATIONS
Since cellular telephones are designed having in view the best possible transmission of the
voice signals, it is reasonable that the data compression systems, which are used in cellular
communication, introduce distortions into the audio signals transmitted. For this reason,
transmission of modem signals (downloading) through a simulated telephone line may be
difficult.
Cellular telephones make limitation in using the remote control function by DTMF signals. Not
every type of cellular telephone can generate the proper form of these signals. Some models
of cellular telephone have a special function permitting the DTMF control - in such case, this
special function is to be activated.
The function of remote control by DTMF signals are always available from a traditional,
stationary telephone set. The only limitations in this case can result from the quality of
telephone cables and the telephone signal level, which reaches the module.

The module has the built in LCD display which is used for reading the information on
the current status of the module, and for programming the data required during normal
operation.
In the first line of LCD display (during normal operation), the following information is
displayed: the telephone line status, the SIM300C telephone status, power level of the signal
received by antenna (0-4) and the status of the inputs and the outputs of the module. The
status of receiving / sending modem data is indicated (R and W symbols). The antenna
symbol flashes during the communication of the SIM300C telephone with GSM base station
(during telephone connection as well). In the second line, the information about the current
status of the module is displayed (e. g. dialing, loss of telephone line, telephone number at
dialing and others).
Notes:
•The "Phone line loss" message is displayed when cable telephone line (subscriber’s line)
is not connected to TIP and RING terminals or to LINE socket - this is a normal operation
condition in case of the loss of such line. It is possible to disable the function of displaying
this message – just deselect the „Show T l.failure" option in the main menu.
•The SIM300C telephone will not start dialing if the antenna signal level is equal to zero.
The status of inputs and outputs are displayed alternately (2s/2s) at last four characters of
top line on LCD display (counting from the left to the right) in a form of the following symbols:
SYMBOL MEANING
i normal status
t normal status
I violated
T violated

Simultaneous pressing and holding for one second both push–buttons, ESC and OK., makes
the restart of the module, with program version being displayed on LCD display. The restart
of the module does not change the status of inputs and outputs. In case of the loss, and then
the restoration of power supply of the module, its inputs and outputs are restored to the
status before the disconnection of power supply.
The cables of telephone lines: public exchange line (subscriber’s) and extension line (to the
alarm control panel and telephone set) can be connected to the terminal strip or to the
telephone jacks located on the board.
4. OPERATING INSTRUCTION FOR THE SIM300C CELLULAR TELEPHONE
The SIM300C industrial cellular telephone, similar as any other cellular telephone, can be
operated by SIM activation card. The user of the GSM-4S module and the SIM300C
telephone has to obtain such card. The SIM card is inserted into a special socket provided at
the bottom of the printed circuit board.
PIN code, if necessary, is entered in the module’s memory by the service function from the
sub-menu "GSM options". The change of PIN code or entering PUK code, if needed, is only
possible after putting the SIM card into an ordinary cellular telephone.
While making connection, the telephone transmits its own identifier (ID), unless this function
is reserved at GSM operator (change of option is available via normal telephone set).
The SIM300C cellular telephone set is delivered with special cable fitted, having a connector
for external antenna (see fig. 2).
5. INSTALLATION
It should be remembered during installation that the GSM-4S module must not be located in
the vicinity of electrical installations, since this may involve a risk of malfunctioning. Pay
special attention to how the cable is laid between the module and the telephone jack of the
alarm control panel.
CAUTION: Never turn on power supply of the module and SIM300C telephone
without external antenna connected.

User Manual GSM-4S

The following sequence must be strictly observed while putting the module into operation:
1. make complete wiring.,
2. turn on power supply of the module without SIM card inserted into the socket on the
electronics board - "Set the PIN code" message will be displayed by the module.
3. activate the service mode of the module and, where the module may have been
preprogrammed before, call the "Delete all" service function (which will restore default
settings),
4. enter the PIN code,
5. switch off power supply,
6. insert SIM card into the
module (see Fig. 4),
7. turn on the power supply
again and program the
module as required.
Notes:
•If the SIM card fails to
accept the PIN code, a
"Bad PIN, go on?
ESC=Stop" message will
appear. The module will
wait 60 seconds for user
reaction, then it will repeat
the attempt to send the PIN
code. Sending a wrong PIN code three times will disable the SIM card. During the
countdown you can press the OK key to immediately resend the code to the card, or press
the ESC key to stop the countdown to make possible a change of the PIN code for the
right one.
•The "GSM phone trbl." message is shown on the display until the SIM300C telephone logs
in the cellular network. This state may last up to several minutes from the module power
supply being turned on.
•The main reasons why the telephone is unable to log in are:
−missing SIM card, SIM card inactive or defective
−insufficient range (antenna signal level = 0)
−antenna not matched to the network range (900/1800MHz) or faulty
−wrong PIN
−SIM300C telephone trouble
The module power supply should have sufficient current capacity. The recommended power
supply (for example, the SATEL manufactured APS-15 or APS-30) should be equipped with
its own battery.
It is recommended that the power supply unit be situated within 3m distance from the
module.
If the supply voltage is lower than 9.8V, restart of the module will follow. Therefore, be sure
that the module supply voltage never drops during operation below 9.8V at the maximum
current consumption.

6. OPERATION OF THE MODULE WITH ALARM CONTROL PANEL AND STATIONARY
TELEPHONE
As shown in Figure 1, the module is to be connected in series between the telephone line (if
it is available) and the remaining devices which use the same line. Where a selection option
is provided, then, using the appropriate service function, determine which output line
(GSM/cable) will be the basic one. The module will test availability of the selected line and in
case of troubles the calls will be routed through a parallel line.
It is possible to disable the function of automatic switchover of the cable telephone line to
GSM by deselecting the "Trouble - switch line" option.
The telephone line simulation mode, in which the GSM-4S module takes over the task of
handling the devices connected to the T-1 and R-1 terminals, consists in providing across
these terminals impedance and voltage required for proper operation of the telephone. From
the point of view of the equipment connected, the module is considered as a typical
telephone exchange providing the cable telephone line.
When the control panel is "off-hook", or when a user lifts the handset of a telephone
connected to the T-1 and R-1 terminals, the module will generate the continuous dialing tone
and receive the tone or pulse dialing signals (similarly as the telephone exchange). If the first
four digits of the dialed number correspond to the pre-programmed "pager station number",
the module goes over to the procedure of receiving the alphanumeric message and sending
it as an SMS text message (see section "Sending SMS messages"). Checking of the first
four digits is always performed.
In case the telephone line is lost or when the GSM telephone has been chosen as the basic
connection mode, the module, after receiving the whole telephone number for outgoing
connection, makes appropriate corrections to this telephone number, and then initiates
dialing and getting connection via the SIM300C telephone. The corrections are necessary,
since the module gets the dialed telephone number as when connecting via the cable
telephone network, while the connection through a cellular telephone requires area codes to
be given. The principles of conversion are described in one of following sections. When the
cellular telephone gets connected, the module transmits L.F. audio signals between the
extension line T-1 and R-1 terminals and the cellular telephone. If the antenna signal level
drops to zero during the communication, the connection will be terminated by the module .
In case the telephone cable line is operative and has been chosen as the basic one, signals
from the telephone set (T-1, R-1) are directly transmitted to the telephone line terminals (TIP,
RING).
The voice messaging initiated by the alarm control panel is effected in a manner selected as
the basic one (if this is impossible, the module selects a substitute way).
When making a call from the telephone connected to the GSM-4S module, the user has the
option to select the connection route: via cable or via GSM. Lifting the handset makes
the basic line available for getting connections. Pressing the FLASH key on the telephone
will change the output line from the basic one to the substitute one (GSM to cable or cable to
GSM). This function of the module is set up by means of the "FLASH – GSM/TL" service
function.
After the handset is lifted by the subscriber the connection is made with, the module changes
the direct voltage polarization across the T-1, R-1 extension line terminals. This function
makes it possible to keep individual tariffication of telephone calls.
Since the SIM300C cellular telephone, has its own number (SIM card number), there is the
possibility of calling to this number. The incoming calls to the SIM300C cellular telephone
are transferred to T-1 and R-1 terminals of extension line, and the ringing tone will be
generated - similar as during making connection via cable telephone line. It is then possible
to answer the incoming call by a telephone set connected to this extension telephone line. To

User Manual GSM-4S
10
enable this function, the option for answering calls has to be selected by the service function
having the same designation. The number of incoming call will be shown on the display.
The capability of answering the calls is utilized for remote controlling the status of outputs
and for bypassing and unbypassing the inputs of the module. The possibility of receiving and
sending SMS text messages via the SIM300C cellular telephone is used for the some
purposes. The function of remote control is described in one of following sections.
The module also uses the CLIP type information for messaging as well as for controlling the
outputs.
7. GSM-4S WITH MONITORING STATION
The GSM-4S module enables monitoring of sites by means of SMS short text messages.
This function is offered by the STAM-1 monitoring station program, version 4.07 or later, and
the STAM-2 program. Connection of the module to station is shown in Fig 5.
Figure 5.
8. DESCRIPTION OF OUTPUTS AND INPUTS OF THE MODULE
The GSM-4S module is equipped with three outputs and four inputs of the technical features
similar to those of inputs and outputs of the alarm control panel. The attendance of the
outputs consists in controlling their operation (switching on for a programmed time period or
Base receiver card
STAM-1 P
PROGRAM
STAM-1 / STAM-2

GSM-4S SATEL 11
permanently), while attending the inputs is connected with supervising their status and with
monitoring the changes of any status. The supervision of inputs can be bypassed. The
attendance of outputs and inputs is performed by the module irrespective of attending the
telephone line.
8.1 OUTPUTS
Outputs (OC – open collector type) are intended for connecting the voltage controlled
equipment. The configuration of the output and the way of connecting the load are shown in
Fig. 6.
It is possible to connect the load resistance R(e. g. Relay) directly to the output, provided
that the load current is not greater than 50 mA.
The output can have one of the two logic status:
"0" – output is OFF: normal status (contact OTn cut off from ground; n=1,2,3),
"1" – output is ON: active status (contact OTn shorted to ground; n= 1,2,3).
The GSM-4S module has 3 outputs, which can be used for controlling the electrical
equipment. The control of the output’s status can be done remotely by telephone (traditional
or cellular), or manually by using the module’s push–buttons. The change of the output’s
status can be also initiated by the violation of the input or CLIP type information.
The remote control can be implemented by DTMF telephone signals or by SMS text
messages.
The control by DTMF signals is possible after getting connection with the number of
SIM300C telephone and entering (from telephone keypad) the password for controlling the
output’s status.
The control by SMS messages consists in sending, to the number of SIM300C cellular
telephone, the SMS text message which contains an appropriate password. The text
message can be sent from a cellular telephone, or by means of computer and INTERNET.
The status of outputs may be changed in the following way:
•enabling output – if inactive, the output will be switched on; if active, the output status will
not change. If a cut-off time has been programmed for the output, it will be disabled after
the time expires. When the output is active, further commands of the „switch on output”
type will start the cut-off time countdown again.
•disabling output – if active, the output will be disabled, no matter whether it is permanently
enabled or its cut-off time has been programmed. If inactive, the output will not change its
status.

•simultaneous disabling of all outputs – all outputs will be deactivated, irrespective of their
previous status,
•simultaneous enabling of all outputs – all outputs will be activated, irrespective of their
previous status.
The control of outputs is possible upon programming the appropriate service functions
(submenu: SMS control, DTMF control).
8.2 INPUTS
The detectors of both types, NC and NO, can be connected to the module. The type of
detectors is to be entered in the service function. The wires from the detector are to be
connected between the input terminal IN and ground (GND), as shown in Fig. 7.
The first parameter, the sensitivity of the input is programmed for each input. The sensitivity
of the input is defined as a minimum time which must elapse from the moment of the status
change at the input (open for NC input, closed for NO input), in order to classify such change
as violation of the input. This time delay can have the values within the range from 20 ms to
1275 ms.
"The time to restore the input" is the next parameter to be programmed for each input.
Time to restore the input is defined as a time delay which must expire from the termination of
the input violation to the moment in which the module changes the symbol displayed on LCD
display (from Ito ior from Tto t) and re-enables the supervision of input status (4 seconds or
4 minutes).
Controlling the operation of inputs consists in bypassing and unbypassing their operation.
This control can be performed manually or remotely. The manual bypassing option can be
disabled by deselecting the INn bypassed manually option. The remote control is
implemented similarly to the remote control of the module outputs status. The input can be
automatically bypassed after one violation or after three violations of such input (set by the
service function), or after violating another input (designated as the bypassing input).
In case of 1 or 3 violations, the input will be automatically bypassed after termination of the
first or the third violation of the given input (i.e. after normal status of the given input is
restored).
The bypassed status of the inputs as a result of violating the Bypassing input will last as long
as the given input is violated.

9. DESCRIPTION OF METHODS OF CONTROLLING THE STATUS OF THE OUTPUTS AND
BYPASSING THE INPUTS
9.1 REMOTE CONTROLLING BY DTMF SIGNALS FROM TOUCH –TONE TELEPHONE KEYPAD
To have the remote control by dual tone phone push-button, it is necessary to properly
program the module by using the service functions, as follows:
•mark option "Answering calls" as allowable
•set the required "Time of ringing"
•program the password (4 digits) for controlling the status of outputs and for the bypass of
inputs. The contents of the controlling password are loaded into the module’s memory by
the service functions contained in the submenu of the service mode "DTMF control". The
password can not recur. To erase to password completely (to disable a given function),
simultaneously press push-buttons CHANGE and NEXT.
For remote controlling the status of the outputs or bypassing/unbypassing the inputs follows
the sequence:
•dial the SIM300C telephone number from any telephone having DTMF features
•wait until "Time of ringing" is completed after which the module will answer a call and
generate three short sounds (beeps) acknowledging that the module is ready to have the
DTMF controlling enabled.

User Manual GSM-4S
14
Note: When receiving a call, the module applies ringing tone to extension line for the
duration equal to "Time of ringing". Answering a call from this extension line makes it
impossible to use the functions for controlling the outputs.
•Enter from dual tone phone keypad the required control passwords (utilizing DTMF tone
signals). After recognizing the password by the module, the respective action will be taken,
depending on the password loaded. For example, recognizing the password loaded in the
module by the function "DTMF OT2 on" will switch on the OUT2 output , while recognizing
the password programmed by the service function "DTMF bypass IN4" will bypass the
supervision of input 4.
•The module acoustically acknowledges the execution of the function by audible indication
as follows:
àthree short beeps – switching OFF the output (disconnecting the ground), the signal
will also acknowledge execution of the function “DTMF OT123 off” (disabling all
outputs simultaneously),
àfour short and one long beeps – switching ON the output (short circuit to ground),
such signal also acknowledges the execution function "DTMF OT123 on" (switching
ON all outputs)
àafter implementing the function for bypassing/unbypassing the input , the module
automatically checks the status of the inputs and generates four sounds
corresponding to the status of consecutive inputs (1 – 4)
−short beep – input unbypassed
−long beep – input bypassed
(for instance: the sequence of signals – short, long, short, long indicate that
inputs 1 and 3 are unbypassed, and inputs 2 and 4 are bypassed)
àtwo long beeps – the password is unknown to the module
•Enter the next control password or hang up.
The additional feature of the DTMF control function is the capability of checking the status
of the outputs without necessity of switching these outputs. To obtain such possibility, enter
from a telephone keypad the password programmed by the service function "DTMF check
outs." After reading the password, the module generates the sound signals indicating only
these outputs, which are ON (with the exception of situation when all three outputs are OFF):
àone short beep – output OT1
àtwo short beeps – output OT2
àthree short beeps – output OT3
àfour short and one long beeps – all three outputs are OFF
For example: if, after entering the password, one beep is heard in a telephone receiver, and
then after a while three beeps are heard, it means that the first and the third output (OT1 and
OT3) are ON, and the second output (OT2) is OFF.
Note:
•During checking the status of the output which was switched in monostable mode, the
module informs about the normal state (stable) of the output before switching over –
irrespective of switching time.
9.2 REMOTE CONTROL BY SMS MESSAGES
The remote control by SMS text messages is enabled by entering appropriate password in
the module’s memory. The contents of the control passwords are loaded in the module’s
memory by the service functions contained in the submenu of service mode "SMS control".

GSM-4S SATEL 15
The passwords can not recur. To erase to password completely, simultaneously press push-
buttons CHANGE and NEXT.
To have this control feature enabled, send to a text message containing the required control
password (6 characters) to the SIM300C telephone number. After decoding the password by
the module, an appropriate action will be initiated, depending on the password transmitted.
E. G.: Recognizing the password entered into the module memory by the function „SMS OT3
on” will enable the OT3 output for the time entered into the module memory with the function
„OT3 cut-off t.”, or permanently, if the time is zero. Recognizing the password entered in the
module’s memory by the function "SMS unbypass all" will result in unbypassing all module’s
inputs which were bypassed.
It is possible to send to the module a message containing the password only, but it is also
permitted that the contents of the message can be longer than just the password (the
password can be a part of a longer word). It is important that the password be inserted at the
initial part of the text message (32 first characters). This feature enables the user to load the
description of the operation in words into the memory of the telephone, from which the
controlling is to be executed (SMS to be sent). This capability will keep the user free from the
necessity of remembering the passwords or the functions, which these passwords execute.
Only one control password can be sent in one message. Transmitting SMS message not
containing the password will make no response of the module. The control function is
executed directly after receiving the message and recognizing the control password. The
message received will be then cancelled, and the telephone is ready for receiving the next
text message.
9.3 ACKNOWLEDGEMENT OF EXECUTING THE SMS CONTROL
If the number to be used for acknowledging the SMS control and SMS centre number are
pre-programmed in the module’s memory (service functions: "SMS acknowl. No.", "SMS
centre No."), then after executing the control of individual output by SMS message, the
GSM-4S module sends the message confirming the type of control and the present status of
outputs. The acknowledgement can also be sent to another telephone number. For the
module to forward an SMS to a different number than that programmed in the module, it is
necessary to insert this number after the control message in the following way: „xxxx=yyyy.",
where „xxxx" denotes the control code, and „yyyy" - the telephone number to which the
message is to be sent by the module. Put the equality sign before the telephone number, and
the dot after the telephone number.
Controlling all outputs simultaneously or bypassing/unbypassing the inputs is confirmed by
the message on the present status of all inputs and outputs of the module as well as the
telephone line status, test transmission period and current telephone numbers to be notified.
The message transmitted by the module can have one of the following forms:
•OUT [n] switched ON (status: OT1 = ? OT2 = ? OT3 = ?)
•OUT [n] switched OFF (status: OT1 = ? OT2 = ? OT3 = ?)
•Status: IN1 =?, IN2 =?, IN3 =?, IN4 =?, outputs: OT1 =?, OT2 =?, OT3 =?, LT=?, test:
??d??h??m Tel1=?...? Tel2=?...? Tel3=?...? Tel4=?...?
when character „[n]" is replaced with the output’s number: 1, 2 or 3.
For designation of the output, character "?" is replaced with the logic state (i. e. the status) of
the output:
0 - output switched OFF (inactive)
1 - output switched ON (active).

User Manual GSM-4S
16
For designation of inputs, character "?" is replaced with the letter:
ior t- input in normal status unbypassed (non-violated),
Ior T- input unbypassed violated,
b- input bypassed.
For the telephone line designation, the "?" character is replaced with the following ones:
ok - the telephone line in good working order,
?? - the telephone line out of order.
In the test field, the module will send the currently programmed number of days, hours and
minutes of the test transmission period.
In the telephone number description, the ?...? characters are replaced by the programmed
telephone number to be notified.
Notes:
•The module always acknowledges the stable status, in which the output remains after
completing the control (for the monostable switched output – the status in which the output
will go after the switching time expires).
9.4 CONTROLLING THE OUTPUTS BY THE VIOLATION OF INPUTS
The violation of input, besides the telephone messaging, can also result in activating any
output or several outputs simultaneously. To initiate such control it is necessary to program
relevant functions from submenu "Inputs/Outputs" (see section "Description of functions for
programming the module").
This control can result in:
•Enabling output – if a cut-off time has been programmed for the output, it will switch on
for the time specified.
•Disabling output.
9.5 CONTROLLING OUTPUTS BY MEANS OF CLIP FUNCTION
The module allows you to control the outputs by using the CLIP feature. To this end you
should call the module number from a corresponding telephone number. The module will
decode the number from which the connection is initiated, count the "calling time", reset the
connection and perform control. If the module user answers the call earlier from the
extension line (T-1, R-1), or if the calling party hangs up, the function will be interrupted and
the control will not be performed.
An option is provided to save 4 telephone numbers in the module memory and assign to
these numbers suitable control of one output or some outputs simultaneously. Operating
mode of the outputs is much the same as for control of the zone violation.
In order to start the CLIP control function, you should:
•select the "call answering" option
•program the "calling time"
•program the functions from the "CLIP control" submenu (telephone numbers, way to
control the outputs)
Notes:
•In some GSM networks the unanswered calls are, after elapse of a certain time delay,
automatically transferred to the voice mailbox. If the "calling time" is longer than the call
transfer time, the control will not be performed. If this is the case, you should limit the
"calling time" so that the module can reset the connection by itself and perform the control.

GSM-4S SATEL 17
•In order to fully utilize the CLIP control idea and to control the outputs without paying the
charges for telephone connections, you should disable the voice mail function. Rejection
of a call with enabled voice mail service will divert it to the voice mailbox, the call being
counted as realized. The call charge is borne by the calling party.
9.6 MANUAL CONTROL
9.6.1 Outputs
During normal operation, pressing and holding one of the module’s push-buttons for the
duration of 1 second will result in enabling/disabling the output, the number of which
corresponds to the push-button’s number. The message on the output’s status is
displayed on the LCD display and the module simultaneously generates the sound
signal identical to that during remote control by DTMF signals. If the output is enabled
permanently, it is indicated on the LCD display by the „O” character, and if disabled - by
the „o” character. If the output is enabled for a specified time, the „O” character is
blinking.
The following push–buttons are used for controlling the status of outputs or for
bypassing/ unbypassing the inputs:
1. ESC - controlling OT1; bypassing IN1
2. CHANGE - controlling OT2; bypassing IN2
3. NEXT - controlling OT3; bypassing IN3
4. OK - switching OFF all outputs; bypassing IN4
9.6.2 Inputs
The manual bypassing/unbypassing the inputs is also implemented by the GSM-4S
module’s push–buttons. Pressing one of these push–buttons three time will cause
bypassing the input of the number corresponding to the number of a given push–button
(see: description of module’s push–button). The bypass of this input will be confirmed
on LCD display by displaying character "b" in the field indicating the status of a given
input, and by displaying the "Inp. n bypassed" message, where "n" = 1,2,3,4
corresponds to the input’s number. At the same time three short beeps are generated. If
this input has been already bypassed, the execution of this operational sequence will
result in unbypassing this input. Unbypassing should be acknowledged by changing the
indication of the input’s status, by displaying the message "Inp. n unbypassed" and by
audible signals (four short and one long beeps).
The function of manually bypassing particular inputs can be disabled. To do so,
deselect the "Inp.n bypassed manually" option, where n denotes the input number. The
inputs can be manually bypassed at all times.
10.MESSAGING
This function is related to the attendance of module’s inputs, and is activated by violation or
restoration to normal status (termination of violation) of the input, which is not bypassed.
Activation of output OT4 or its restoration to normal status, can also initiate messaging,
similar as for input.
Another form of messaging is the „test transmission”. In order to inform the user of its
operability, the module will send an SMS with suitable contents, or call selected telephone
numbers within the programmed time period. Information on the status of outputs, inputs, and
telephone line availability can be attached to the SMS message.

User Manual GSM-4S
18
The messages can be sent maximally to four telephone numbers. The messaging can have a
form of SMS message, the sound information or CLIP type information. For the voice
messaging, it is possible to initiate the function of calling a given number twice (two phone
connections with replaying the message each time)
It is possible to disable the function of messaging individually for each input, if the cable
telephone line is operative: messages will only be sent by module if the cable line is
damaged. In order to do so, deselect the "TL ok, mess.Input n" option for the selected input,
where n means the number of input. The status of such inputs will be indicated with "t" or "T"
letter on LCD display and in SMS messages, provided that the telephone line is OK.
However, when the analog telephone line is out of order, these symbols will change into "i" or
"I", which means that messaging from those inputs will be effected.
The telephone numbers to be notified and the test transmission period can be remotely
changed by sending SMS messages to the module. Such messages must contain the proper
password and the programmable parameter (see: Description of functions for programming
the module).
10.1 SMS MESSAGES
The SMS messages to be transmitted can have standard contents or can be modified by the
user. The user's own message can be entered by using the module’s push–buttons or by
utilizing the SMS message sent from another telephone to the SIM300C telephone number.
The contents of messages are entered by special service mode functions (submenu
MESSAGING).
To change the contents of a standard message, it is necessary to follow the steps:
•Initiate the service mode.
•Go to submenu MESSAGING.
•Select appropriate function for programming the contents of SMS message.
•Read the present contents of the message, after recalling the selected functions. By using
push–buttons NEXT and CHANGE it is possible to enter your own contents of SMS
message regarding the event which corresponds with the function’s description.
•Accept the introduced changes by pressing push-button OK, and proceed with
programming the next message, or abort the operation of service mode.
To enter the contents of the message by means of another cellular telephone, it is necessary
to follow the sequence:
•After recalling the function for programming the contents of a message, simultaneously
press and hold push-buttons NEXT and CHANGE .
•If the contents of present message are standard, the information "Read-out from SMS"
will be displayed on LCD display, and the module will go into "awaiting for SMS message
mode" for the duration of approx. 110 seconds.
•Send SMS message (previously prepared) from another cellular telephone to the SIM300C
telephone number. The message to be sent should be of a special format. The contents of
the message, which is to be loaded into the module’s memory should be put into brackets
and closed by asterisks, as follows: (¼Contents of message¼).
Notes:
•If, after recalling the function, the contents of the displayed message is not standard,
pressing and holding the push-button NEXT and CHANGE will cancel this message, the
next pressing will result in displaying the standard message and only the successive
pressing will make it possible to load the message by means of SMS message.
