When the modem has been connected to the
operator’s network, the light diode
Relay
stops
flashing and the light diode
Signal Strength
starts
flashing to reflect the Power of the signal being
received. The light diode is pulsing, and the quantity
of pulses refers to the Power of the signal.
One pulse refers to the lowest signal, 7 pulses refer
o the highest signal.
When the device reaches the last stage specified in the table, it is ready for use.

The device is able to receive 3 types of command messages:
1.
Recording a number in the data base of numbers
2.
Recording the time of the delayed switching-on-the-relay signal
3.
Recording the status of receiving an external switching-off-the-relay signal
SMS message containing a command for recording a number is as follows:
P
#nnn=xxxxxxx;
The symbol “
P
” should be in the first position, instead of
nnn
there must be a number
to be recorded in the device memory,
xxxxxxx
means a recorded phone number which the
device would respond to.

Note
: the device will not respond to SMS that contains configuration commands, unless
senders phone number is entered to 0th position in internal database of phone numbers
