Anti-Theft and Startup Protections
Anti-Theft
Protection
Purpose
The SP60 integrates an anti-theft function to protect your
equipment while it is left operating unattended.
This protection is intended for a SP60 operated as a base.
The anti-theft protection will discourage the theft of an SP60
receiver by rendering it useless without the anti-theft
password.
Enabling/Disabling the Anti-Theft Protection
The anti-theft protection is enabled and disabled from the
data collector controlling the receiver. If you use the Spectra
Precision
Survey Pro or FAST Survey on your data collector, a
user-friendly interface will let you quickly enable or disable
the anti-theft protection (see
Using Anti-Theft and Startup
Protections in Survey Pro on page 32 and Using Anti-Theft
and Startup Protections in FAST Survey on page 34 ).
If you are using other software, please contact Technical
Support for more information.
How the Receiver Operates With the Anti-Theft On
With the anti-theft protection enabled, and as long as no theft
is detected, the receiver will operate normally.
What the Anti-Theft Protection Does Initially
At the time the anti-theft protection is enabled, the last valid
position computed by the receiver is saved in memory. This
position is saved as the
anti-theft position .
NOTE: You won’t be allowed to enable the anti-theft
protection until the receiver can compute a position solution
in standalone mode for its location.
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 .
