What Events Will Trigger a Theft Alarm?
From the moment the anti-theft protection is enabled (and an
anti-theft position has been saved in the receiver), a theft
condition will be detected, and an alert will be issued:
• If the receiver has unexpectedly been unable to deliver a
valid position for the last 20 seconds or so.
• Whenever the protected receiver computes a valid position
that is distant by more than 100 meters (around 330 feet)
from the anti-theft position.
What Will Happen When a Theft is Detected?
The protected receiver will switch to “theft mode”, that is:
• The buzzer will regularly emit a sound alarm in quick
succession, and for an indefinite period of time.
• The front panel display will read: “ ANTI-THEFT ALARM”.
• All output messages will be stopped (the protected base
receiver will no longer generate and transmit corrections,
or any other NMEA or raw data messages).
• If the internal GSM modem is used, a text message (SMS)
and/or an email will be sent every 1 minute to,
respectively, the phone number(s) and/or email
recipient(s) you indicated when programming the anti-
theft protection. Both the text message and email will
contain the base’s last computed position to help you
track the thief.
• The three front panel buttons of the protected receiver will
be made inactive, which means no one can:
– Power off the receiver
– Reset the receiver
– Upgrade the receiver.
What if the Thief Removes the Batteries?
If the thief removes the batteries before vanishing into thin
air with your receiver, be sure the theft will be detected
sooner or later. Next time the receiver is powered back on,
because the protection is still active, the theft alarm will be
set as soon as a valid position is computed and found distant
by more than 100 meters from the memorized anti-theft
position, or no valid position is delivered for 20 seconds or so.
