Figure 1. IR-OptiFlex Focus
To operate with IR-OptiFlex focus in manual mode or to fine tune the focus,
turn the one-touch focus control in a clockwise or counterclockwise direction.
As you turn the focus control, you will see a live thermal image on the display
as it changes. When your target comes into focus, it shows a sharper image.
When the target moves out of focus, the image becomes blurry.
Primary and Secondary Triggers
The two-part trigger is located in the standard trigger position for a pistol-grip
device. The larger, green trigger is the primary trigger. The smaller, black
trigger is the secondary trigger.
In normal operation (video is off), the function of the primary trigger is to
capture a thermal image for possible storage to memory by the user. When
video is on, the primary trigger is the start/stop for video recording.
The secondary trigger operates the laser and torch. For information about how
to enable the laser and torch, see pages 31 and 32.
