1.2.1. Battery Management

 
 
After the batteries are installed or replaced, the Battery management menu appears when the camera first starts up. This menu can also be displayed by pressing and holding down the F2 button when the camera is powered ON.
I
n the Battery management menu, the function buttons perform the following:
F1 confirms the information entered, closes the window, and initializes the settings.
F2 edits and confirms entry of the selected item.
F3 cancels an entry or closes the window without resetting the battery
options.
The Battery management menu can operate in one of two modes:
A
dvanced Off (Default) is display-only; you cannot change any settings in this mode. In default mode, the
battery icon only appears when battery power is low. When this icon appears, the camera will operate for approximately 30 minutes and then shut down automatically.
Ad
vanced On allows more precise tracking of battery energy consumption, including the type of batteries used
and their estimated capacity. In Advanced mode, the battery icon indicates how much charge is left in the batteries. Initially this icon is green: 30 minutes of charge remains, this icon appears as .
. When the remaining charge is low this icon appears yellow: . When
T
o change mode, ensure the Advanced icon is selected. If not, use the arrow buttons to select it. Press to edit
the setting, and use the up and down buttons to change the setting to the desired option. Then press to confirm the change.
Ty
pe of batteries: The camera is delivered with low-self-discharge NiMH rechargeable batteries with a capacity of
approximately 2500mAh. These are the default parameters.
If you consistently use the same set of rechargeable batteries, we recommend operating the camera until it automatically switches OFF due to low batteries. This automatically recalculates and adjusts the estimated capacity of the batteries. The new capacity is displayed by default the next time the Battery management menu is displayed.

1.3. Micro SD Memory Card Installation

Camera files (images, audio, and setup) are stored in the micro SD memory card located on the left side of the head (see photo to the left). If this card is not installed, an error message appears when the camera attempts to access it. This card is provided with the camera.
efore installation, the memory card must be formatted in one of the

o insert the current date and time into the name. The name can be up to 20 characters long.
6. When the directory name is complete, save it by pressing F1
We recommend creating a directory in the root of the micro SD card to store images. For FAT16 formatting, if long names are used, only 256 entries are available in the root (any combination of 256 files and directories). The card will therefore very quickly be considered full, even though its full capacity has not been reached.

1.5.8. Color Palettes

The camera has three color palettes that can be selected for displaying thermograms. To select a new palette:
1. Press F
2. Select to display a list of available palettes. Choices are Steel (black, purple, yellow to white), Grayscale (black to white), and Rainbow (blue, green, yellow, to red). Steel is the default.
