Hot Button 2 – Freeze/Save
Hot button 2 freezes the live thermal image. It is possible to edit the image in freeze mode before saving it.
Pressing hot button 2 again saves the image as an image.iri file to the SD card, while pressing hot button 1
instead rejects the image. The file saving takes a few seconds, and the file name is given a sequential number.
See Section 5.3.1.1.4 for how to save an image direct to a PC via the USB cable.

Hot Button 3 - Direction Buttons Control.
Hot button 3 selects either the SP+ or SPX temperature measurement cursor, or either B-C (thermal image
brightness & contrast) when in auto mode or L-S (temperature level and span) when in manual mode. The 4
direction buttons are then used to adjust the position of the selected cursor, the level & span, or the brightness
& contrast depending on which mode is selected. Note that SPX must be enabled in the Measurement Settings
menu, and that the B-C control is an advanced user function that must be enabled before use in the Camera
Settings menu.
3.4.4.4
Hot Button 4 – Auto / Manual
This hot button toggles between auto and manual mode. In auto mode, the imager continually adjusts the level
and span to achieve the optimum image. In manual mode it is possible to manually control the level and span
to produce the image to your requirements. See Section 3.4.6.1 for definitions of level and span, and Section
3.4.9.1 for definitions of brightness & contrast. The preset brightness and contrast of the auto mode can be
adjusted to suit your preferences. (See Section 3.4.9.1).
