2. Beacon mode (coordinates by timer)
Vehicle’s location is sent via SMS to master-phone
number at a certain time or within certain intervals set
by the user. At all other times the beacon is sleeping to
reduce power consumption and not to be discovered by
radio scanners.

The exact time and frequency of SMS requests for car
coordinates can be set in 2 timers.
By default,
Timer №1
is set to wake up every hour and
wait for 10 minutes to receive user’s SMS commands
sent before.
By default, the
Timer №2
is set to wake up every day at
12:00 (UTC+0), to send SMS message with current car
GPS-coordinates to master-phone number and to wait
for 10 minutes to receive user’s SMS commands sent
before.
If the signal from satellites at wake-up time is weak or
lost the location will be determined via GSM network.
You can change the timers’ configuration by sending
SMS-commands, see p.21.
