Trails

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.

To change the Trails setting:

1. Using the ARROW KEYPAD, highlight the desired setting.

2. Press the ENTER key to accept the change.

Trails - Off

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.
