Description
The above picture shows the arrangement of the user operating features.

►This manual assumes the camera is loaded with the latest firmware available at the time
of writing. Functionality may vary with earlier or later firmware versions.

Cards
You should always use micro SDHC or Micro SDXC cards with an UHS speed class rating
of U3 and/or a video speed class rating of V30, V60 or V90. Both FAT32 and exFAT are
supported, but it is recommended to always format cards with a capacity above 32GB in
exFAT. In-Camera Formatting (see below) will do this automatically.
Although it is recommended to use cards with a capacity of 64G or 128GB, cards with a
capacity of up to 1TB have been tested.
Clips recorded on cards formatted in exFAT can be recorded as max. 60GB clips. Clips
recorded on cards formatted in FAT32 can be recorded as max. 4GB clips.
If a specific card does not work correctly after it has been freshly formatted you should no
longer use the card with the camera. A different card, even an identical card, will most
likely work perfectly.
►If the Video clip length is set to Max. there will always by a 2-3 second gap between
clips.
►If the clip length would exceed the 4GB boundary on a card formatted to FAT32 (for
example, 4K resolution and Video Quality set to High) the clip will be recorded as a 4GB
clip and there will be 2-3 second gap between the next clip.
►Important: If the firmware detects that the card is too slow (class rating too low), the clip
will be saved and the camera will return to standby mode.

Formatting Standard formatting tools provided by the operating system are not always reliable and should not be used. In addition, they do not optimize the SD card's performance. For optimal card performance it is recommended to either use the Windows setup program (mSetup, see below) or use the camera's built-in formatter. - Page 3 The TV Out function does NOT have any sound, so only the video (Yellow) connector needs to be connected to the monitor video input. The other pigtail (red/black wires) is for external +5V Power IN, which is optional for when the camera’s internal battery cannot power the camera long enough.
