Skipping GPS positioning
If you want to start measuring immediately, or if GPS
positioning is taking too long, select
Skip
during GPS
positioning and start measuring.
GPS positioning continues while measuring, and when
positioning is complete the device starts recording
positional information. The routes before GPS
positioning is complete and while using indoor mode
are not recorded. Distance and pace data can still be
measured. The device will use the stride sensor until a
GPS connection is made.
U
Indoor mode
This function allows you to measure without
performing GPS positioning. Use this when GPS
positioning cannot be performed because you are
indoors and so on.
The route and so on is not recorded in indoor mode.
Also, measurement items are limited in indoor mode.
