See the Programming Multicell section for various modes of charging.
a) Charging signal not generated at all.
Multicell generates a 12/16 KHz or Polarity reversal charging signal when the conversation starts and sends it to
the telephone or to the exchange.If the GSM network sends the 12/16 KHz charging information to the device
Multicell repeats that to the telephone (or to the external line of the PBX).But if the 12/16KHz charging
information is not sent by the GSM network Multicell generates the 12/16 Khz or Polarity Reversal according to
the following programming modes:
7. 12/16 KHz or POLARITY REVERSAL CHARGING SIGNAL
6.1
It is possible to increase the receiving voice level during the conversation just for that call.If you press digit 9
for longer than 1 second the received voice level is increased one level.Pressing digit 9 each time increases the
voice level one unit.The received voice level may be increased up to level 7 and when the telephone is hooked-
on the level returns back to the programmed value.
5.1
When the power is up the GSM network signal level LEDs will lit on randomly until the connection is
established with the network.Then the signal level LEDs will be lit on according to the network signal level
detected by the device.
5. START UP THE DEVICE
. If the telephone HOOK OFF LED is on (the bottom LED) it means the telephone or

properly.
If the received GSM signal level is weak only LED1 will lit on. However the device still may work
If the received GSM signal level is medium LED1 and 2 lit on.
Level 2 signal
If the received GSM signal level is maximum LED1 to 3 lit on.
4.1 Antenna Connector
The device antenna is screwed to the antenna connector.
4.2 Adapter Socket
220 VAC /9VDC adapter is connected to the device.
4.3 Serial Interface Connector (optional)
It is possible to make connection between the device and PC through this connector in order to send
SMS messages from PC.
4.4 Telephone or Exchange(PBX) Connector
The device may be connected to a telephone or to an external line of a PBX (FXO) with the line cord
provided (Fig.3).

4. CONNECTIONS AND MEANINGS OF LEDs ON MULTIcell
3.5
Connect the one side of the line cord to the device and the other to the telephone or PBX external line.
3.6
Insert the adapter jack to the device power socket and than connect the adapter to the 220 VAC line.
Multicell will start operating in 5 seconds and it will search to establish the operator connection.
When the connection is established the signal level LEDs will be lit according to the signal level.

If LED1 does not lit on it means the device can not receive the GSM signal at all and keeps searching
the signal as when the first power is on. During the search of the signal LEDs will be on and off.When
the connection is established the LEDs will be stable on.If the signal is very weak so that the device do
not work properly it may be necessary to change the location of the device or use an external roof
antenna.
PBX external line connected to the device is hooked- off.
. If only LED3 is blinking it means SIM card is not inserted to the device.
. If only LED2 and LED3 are blinking it means the pin code of the SIM card inserted
to the device is not canceled.
5.2
If the dial tone is received when the telephone or the external line of the PBX is hooked- off it means the
device is ready to operate.
If a continuous dial tone is not heard it means the device has not established the connection to the network.
5.3
To dial a number,hook-off the phone or seize the external line of a PBX . The dial tone of the device is
heard.The number is dialed.The ringing tone is heard and when the called party answers the talk starts.
If the called number is busy you hear the busy tone.
5.4
If there is
an external call to the device the telephone or the external line connected to the device rings.
Hook-off the phone and the conversation starts.
6. ADJUSTMENT OF THE VOICE LEVEL
6.2
It is also possible to adjust the received voice level by programming the device for all calls.The received
voice level is adjusted in 7 levels (default level is 4).Please see the “8. Programming Multicell”section for more
details.
6.3
The transmitting voice level is only adjusted by programming the Multicell device.The transmitting voice
level is adjusted in 7 levels (default level is 4). Please see the “8. Programming Multicell” section for more
details.
b) Charging signal generated only once at the begining of the conversation.
c) Charging signal generated when the conversation starts and keep generated according to the intervals
entered by the user.
Default : 12 KHz is generated at the beginning of the conversation and in each 6 seconds during
conversation.
