Trails are history trails that show movement of a target. When Trails 

is On, all returns on the display leave a history trail. The Trails setting 

determines the length of the trail. The Trails setting has four presets: 

Off, Short, Medium, and Long. 

1.   Using the 

ARROW KEYPAD, highlight the desired setting.

2.  Press the 

ENTER key to accept the change.

To clear the Trails, select Clear Trails on the Adjustment Menu or 

press the Clear Trails Soft Key.

A Guard Zone is a user defined area of protection. If a target enters 

the defined Guard Zone, an alarm is sounded. Two Guard Zones can 

be defined at any given time.
The Guard Zone Menu has two areas, “Guard Zone 1” and “Guard 

Zone 2.” Each area has two settings, a setting to Show/Hide the 

Guard Zone, and Adjust.
