Characters are not displayed. Charts are difficult to move.	Adjust the font size or set the mobile device to horizontal screen from your mobile device settings. Holding down on the screen will enlarge the data section, so it will be easier to see.
The date in the name of the HST file does not match the date and time of the last data in the file.	The name of the HST file is set to the date and time when the SAVE (save) button is pressed by default, but the contents (data) actually saved as an HST file are the operating data up to the point when the name was fixed. Therefore, the date and time in the name of the HST file may not match the date and time of the final data in the actual HST file.
