What do the white boxes on my watch screen mean?

The following article explains what the white boxes mean on a V2 when in a game mode.

The boxes on the screen indicate what screen number is currently being viewed. Depending on which mode you are playing there are a different number of screens. The screen being viewed can be changed by pressing the menu button (the left middle button).

The most popular game mode, 'GPS + Track', has 5 screens:

1. GPS distances

2. Penalties

3. Manual PinCollect 0-3

4. Manual PinCollect 4

5. End Round

Below shows the GPS distances screen changing to the Penalties screen. You can see the white box has moved down a space.
