2.9 CALIBRATION After prolonged use, or after transitions from one temperature extreme to another, a degradation of the thermal image may be noticed. In these instances, and during initial startup, the WTM should be calibrated to optimize the viewed thermal image. Calibration is accomplished by simultaneously pressing (and holding) the UP / DOWN buttons, or via the system menu (see section 2.16, Calibration (CAL)). Regardless of which method is used, the objective lens cover must first be placed over the objective lens. Failure to do so may result in a distorted picture or the presence of ghost images in the eyepiece display. The WTM is equipped with an internal sensor that detects significant changes in temperature. When this condition occurs, the message “RECAL” will appear in the eyepiece display indicating that the operator should calibrate the WTM as described above. 2.10 DIOPTER ADJUSTMENT The eyepiece may be focused to accommodate differences in individual operators’ eyesight. Diopter adjustments may be made as follows: 1. With the system powered on, press the PWR button to

call up the Main Menu. 2. While looking through the eyepiece display, rotate the

diopter adjuster until the menu text appears sharp and clear.
