Power Levels

 

You can get an idea of the watch’s power level by

 

observing the movement of the x Second Hand in the

 

Timekeeping Mode.

 

ξ If the x Second Hand is moving normally at one-second

 

intervals, power is at Level 1.



ξ If the x Second Hand is moving at two-second intervals,

 

power is at Level 2, which is quite low. Expose the watch

 

to light as soon as possible so it can charge.

 

 

Moves at two-second intervals.

ξWhen power drops to Level 3, all functions will be disabled but the watch will continue to keep time internally for about one week. If you recharge the battery sufficiently during this period, the analog hands will move automatically to the correct setting and regular timekeeping will resume. After one week, all settings (including timekeeping) will be cleared. Recharging the battery will reset all settings to their initial factory defaults.

Power Recovery Mode

The watch is designed to go into a power recovery mode that stops hand operation temporarily whenever power suddenly drops below a certain level due to overuse of the alarm tone over a short period. Note that all operations are disabled while the watch is in the power recovery mode.

The hands will move to the correct positions and the watch will resume normal operation after power recovers (in about 15 minutes). Putting the watch in a location where it is exposed to light will help power to recover sooner.

Power Saving

Power Saving enters a sleep state automatically whenever the watch is left for a certain period in an area where it is dark. The table below shows how watch functions are affected by Power Saving.

ξThere actually are two sleep state levels: “second hand sleep” and “function sleep”.

ξ Internal timekeeping maintained

 

 

To recover from the sleep state

Move the watch to a well-lit area or press any button.

ξThe watch will not enter a sleep state between 6:00 AM and 9:59 PM. If the watch is already in a sleep state when 6:00 AM arrives, however, it will remain in the sleep state.

ξThe watch will not enter a sleep state while it is in the Stopwatch Mode.

Mode Reference Guide

Your watch has four “modes”. The mode you should select depends on what you want to do.

Selecting a Mode

With this watch, everything starts from the Timekeeping Mode.

To determine the watch’s current mode

Check the position of the v Left Dial Hand as shown under “To select a mode” (page E-19).

 To return to the Timekeeping Mode from any other mode

Hold down C for at least two seconds.

To select a mode

Press C to cycle between the modes as shown below. The v Left Dial Hand indicates the currently selected mode.

The v Left Dial Hand rotates so the indicator for the current mode (TM, ST, WT, AL) is aligned with the pointer .
