To measure a temperature

[1] Press the 

↵

 button to display the menu system.

[2] Go to the 

Spot

 function in the menu tree by moving the joystick to the left or

the right. The 

Spot

 function is located in the 

Analysis

 menu. Press the 

↵

 button

when 

Spot

 is highlighted. The spot meter crosshair will now appear in the

image and the measured temperature will be shown in the upper right corner
of the display. If the multiple spots option is selected in the setup menu (

Set-

up

Multiple spots

→

On

), the 

Analysis

 menu will display 

Spot 1,

Spot 2 

and 

Spot 3

 instead of 

Spot

.

[3] To move the spot meter crosshair on the screen the function has to be high-

lighted in the 

Analysis

 menu. It can then be moved with the joystick. When the

spot is correctly located, press 

↵

 to go back to the normal function of the joy-

stick (i.e. controlling focus and zoom). To be able to move the spot meter after
the joystick has resumed its normal function, it has to be highlighted and con-
firmed in the 

Analysis

 menu again.

4.2.4

To save an image

[1] Press the 

A

 button and focus the image.

[2] Press the 

S

 button to freeze the image.

[3] To save, hold down the 

S

 button for one second or until the filename (e.g.

E123232

) of the image appears.

Press the 

S

 button briefly to go to live mode.

4.2.5

To add a voice comment to an image

[1] Connect the headset to the headset connector and place it on your head. See

also “Connections” on page 7.

[2] Press the 

A

 button and focus the image.

[3] Freeze the image by pressing the 

S

 button for a short while. 

↵

[4] Press the 

↵

 to get the menu system and go to 

Voice comment... 

in the 

File

menu by using the joystick. Select

 Voice comment... 

by pressing 

↵

. This will

make the control panel for voice comments appear.

[5] Hold down the 

S

 button while recording. The length of the comment is indi-

cated by * signs in the control bar.

[6] Playback in the headphone indicates that the recording is working.
[7] When the voice recording is complete press the 

↵

 button to save both the

image and the voice comment.

[8] To listen to the comment keep down the 

A

 button.

4.2.6

To add text comments to an image

This function is only possible if a file containing user-defined text comments is
stored on the PC-card. These text comments can be created and edited in
