NOTE: POWER OFF is a low power state. Connect the USB cable
(with power source) to wake up the watch. The initial setup wizard
starts. However, prior values are not erased, so you just need to
confirm each step.
NOTE: The watch switches to power saving mode when it is
static for 10 minutes. The watch re-activates when moved.
NOTE: Service menu content is subject to change without notice
during updates.

3. Press [Start Stop] to confirm GPS reset, or press [Light Lock] to
