This menu gathers all the software setup/management utilities.
Those utilities will set or check the parameters for the watch, other than the usual date and time (available in ADJUST, from MENU 2).
Key
Two touch screen keys appear on this screen, allowing to toggle on/off both the key-pressed "beep" and the extended japanese keyboard.
Turning "jpn" off turns the input keyboard into alphabetic-only mode, whereas "jpn on" will add the japanese Katakana set.
Capacity
No touch-screen key on this display, only the indication of the free memory amount.
Contrast
use the UP/DOWN key to adjust the contrast. The actual time display is an indication of the current contrast setting, and is actually active while setting the contrast
