: Diving Function
This indicates whether or not the watch can be used for diving.
•The 
display means that the watch is insufficiently charged for use during diving. Although the dive mode continues to operate even in this state, if diving is performed while in
this state, the watch may become insufficiently charged during diving. Sufficient charge the watch prior to diving to ensure safety.
•When "NG" is displayed, the watch will not switch to the dive mode. The watch can therefore not be used for diving in this state.
Ir: Infrared Communication Function
This indicates whether or not the infrared communication function can be used for data transfer with a personal computer or between watches.
C. Flash Memory Status Display
This display provides a general indication of the amount of flash memory available. In addition, garbage collection can also be performed during this display by pressing one of the buttons.

D.Garbage Collection Operating Procedure
Garbage collection begins when the upper left button (C) is pressed for at least 2 seconds and then released during the flash memory status display.
•During the garbage collection operation, an alarm sounds and "G.C." is displayed on the display. When garbage collection is completed, "Done" is displayed on the display.
•Garbage collection cannot be performed when "G.C." has changed to "NG" on the charge level indicator. "Fail" is displayed on the display at this time.
<General Reference for Performing Garbage Collection>
Try to perform garbage collection when the black segment on the flash memory status display is larger than the white segment (available memory). Garbage collection consumes considerable power. For this reason as well, in order to ensure that flash memory is used efficiently, it is recommended to perform garbage collection whenever the watch is charged (fully charged).
