Reference

This section contains more detailed and technical information about watch operation. It also contains important precautions and notes about the various features and functions of this watch.

Auto Return Features

•The watch returns to the Timekeeping Mode automatically if you do not perform any button operation for two or three minutes in the Data Recall, Alarm, or Barometer/Thermometer Mode.

•If you do not perform any button operation while in the Altimeter Mode, the watch returns to the Timekeeping Mode automatically after nine or 10 hours (altitude measurement type : LONG) or after one hour (altitude measurement type : SHORT).

•If you leave a screen with flashing digits on the display for two or three minutes without performing any operation, the watch exits the setting screen automatically.

Scrolling

The B and D buttons are used on the setting screen to scroll through data on the display. In most cases, holding down these buttons during a scroll operation scrolls through the data at high speed.

•Even if battery power is at Level 1 or Level 2, the Barometer/Thermometer Mode or Altimeter Mode sensor may be disabled if there is not enough

voltage available to power it sufficiently. In this case, will appear on the display. This does not indicate malfunction, and sensor operation should resume once battery voltage returns to its normal level.

•If keeps appearing during measurement, it could mean there is a problem with the applicable sensor.

To turn the button operation tone on and off

In any mode (except when a setting screen is on the display), hold down C to toggle the button operation tone on ( not displayed) and off ( displayed).

•Since the C button also is the mode change button, holding it down to turn the button operation on or off also causes the watch’s current mode to

change.

• The indicator is displayed in all modes when the button operation tone is turned off.

Power Saving

When turned on, 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.

• There actually are two sleep state levels: “display sleep” and “function sleep”.

Elapsed Time in	Display	Operation
Dark
60 to 70 minutes	Blank, with	Display is off, but all functions are
(Display Sleep)	PS flashing	enabled.
6 or 7 days	Blank, with	All functions are disabled, but
(Function Sleep)	PS not flashing	timekeeping is maintained.

•Wearing the watch inside the sleeve of clothing can cause it to enter the sleep state.

•The watch will not enter the sleep state while the digital time is between 6:00 AM and 9:59 PM. If the watch is in the sleep state already when the digital time reaches 6:00 AM, however, it will remain in the sleep state.

•The watch will not enter the sleep state while it is in the Altimeter, Countdown Timer, or Stopwatch Mode.
