3.5.26 ZONe seNsITIvITY BOOsT
Individually adjusting the sensitivity of the detector's zones helps establish an optimal
detection field. The PD 6500i contains a total of 33 zones: eleven zones from top to bottom and
three zones from left to right. However, for the sake of simplicity in making individual zone
adjustments, these 33 zones are consolidated into six adjustable areas from top to bottom.
These six adjustable areas are displayed on the walk-through's LCD as Zones 1–6. The 33
zones and their corresponding zone lights are shown in Figure 3-2 on the next page.
Each adjustment is based on a percentage of the base sensitivity. The user may
increase or decrease the percentage of the base sensitivity level in 1% increments by press-
ing the + (to increase) or - (to decrease) touchpads. An adjustment of zero percent means
the sensitivity of that area is equal to the base sensitivity.
The zones lights on the detector will light up to indicate the area being adjusted.
The following are a few examples of adjustments for a base sensitivity setting of 150.
ZONE 1= 150+0%
ZONE 3= 150+15% (Zone 3 sensitivity is 15% greater than the base sensitivity)
ZONE 5= 150-15% (Zone 5 sensitivity is 15% less than the base sensitivity)
The adjustment ranges for the zones are as follows:
