When the Power is supplied, the device checks the whole internal data base of numbers
and operation of the memory chip.
If there is a memory error, the device would not switch to operation mode and 2 pulses
would be emitted by alternately by the light diode Signal Strength.
If the GSM modem is not functioning, the device would not switch to operation mode
and uninterrupted swift short pulses would be emitted by the light diode Signal Strength.
In the device, the whole internal data base of numbers is being checked by checking
the control counting (CRC). If the control counting does not match, the device would rewrite
all settings back to manufacturer’s values:
•
The setting of switching off the signal is replaced by “switching off on receiving an
external signal”.
•
The time for switching off the relay is set at 5 sec. However, it is not being used.
•
The data base of numbers is deleted.
When the device is operating, it is possible to connect a personal computer and do the
configuration. In addition, when data is being transmitted from the device to the personal
computer and vice versa, it does not respond to calls and SMS messages.

After purchasing the device it needs to be configured, i. e. the list of numbers which the
device would respond to must be recorded in the memory as well as the parameters of the
switching-on signal of the operating device.
When the device is switched on for the first time, its data base of numbers is empty.
The device must be configured by a personal computer and a programme since the
configuration command by SMS messages may be received only from numbers which are
already available in the data base.
The device is fixed onto DIN board and connected as shown in the labelling on the
body.
Before using the device, insert a SIM card with an unlocked PIN code check. PIN code
check may be unlocked by any mobile phone or other appropriate device. For more
comprehensive information, please refer to the internet service provider, the owner of the
SIM card.
