Important!

• The watch’s Altimeter Mode calculates and displays relative altitude based on barometric pressure

readings produced by its pressure sensor. This means that readings taken at different times at the

same location may produce different altitude values due to changes in barometric pressure. Also note

that the value displayed by the watch may be different from the actual elevation and/or sea level

elevation indicated for the area where you are located.

• When using the watch’s altimeter while mountain climbing, be sure to perform regular calibration in

accordance with the local altitude (elevation) indications. For more information, see “To specify a

reference altitude value” (page E-56).

• Whenever you use the digital compass of this watch for serious trekking, mountain climbing, or other

activities, be sure always to take along another compass to confi rm readings. If the readings produced

by the digital compass of this watch are different from those of the other compass, perform bidirectional

calibration of the digital compass to ensure more accurate readings.

• Direction readings and digital compass calibration will not be possible if the watch is in the vicinity of a

permanent magnet (magnetic accessory, etc.), metal objects, high-voltage wires, aerial wires, or

electrical household appliances (TV, computer, cellphone, etc.)

High-speed Movement

You can use either of the crown operations described below to move watch hands or indicators at high

speed.

HS1: Can be used to move both hands and display indicators.

HS2: Can be used when setting the hour and minute manually to move the hands at high speed.

To start HS1 high-speed movement

While the crown is pulled out, rotate it rapidly three turns away from you (for

forward movement) or towards you (for reverse movement). High-speed

movement will continue even if you release the crown.

To start HS2 high-speed movement

While HS1 high-speed movement is in progress, again rotate the crown rapidly

three turns in the same direction as the current HS1 movement (away from you

for forward movement or towards you for reverse movement).

E-5

To stop high-speed movement

Rotate the crown in the direction that is opposite that of the current high-speed

movement or press any button.

Note

• If you do not perform any operation for more than two minutes after pulling out the crown, the indicator

shown below will appear and crown operations will become disabled. If this happens, push the crown

back in and then pull it out again to re-enable crown operations.

• Pulling out the crown while the watch is in a mode that does not allow confi guration of any settings will

cause the indicator shown below to appear. If this happens, push the crown back in and lock it.

• The indicator shown below also appears when performing hand home position adjustment. See “Hand

Home Position Adjustment” (page E-39) for more information.

• You can use high-speed movement in the following cases: when changing the time and/or date setting

in the Timekeeping Mode, World Time Mode, Countdown Timer Mode, or Alarm Mode, or when

performing magnetic declination angle calibration, altitude calibration, barometric pressure calibration,

or temperature calibration operations.
