E-1

•The watch continues to operate, even when it is not exposed to light. Leaving the watch in the dark can cause the battery to run down, which will result in some watch functions to be disabled. If the battery goes dead, you will have to re-configure watch settings after recharging. To ensure normal watch operation, be sure to keep it exposed to light as much as possible.

• When you are not wearing the watch on your wrist,

position the face so it is pointed at a source of bright

light.

• You should try to keep the watch outside of your sleeve

as much as possible. Charging is reduced significantly if

the face is covered only partially.
