Data Communication Functions

Data is transferred between watches or between the watch and personal computer using the data communication functions. There are two ways for transferring data: the first involves using the infrared communication interface, and the second involves using the communication unit (USB communication interface) function.

1.Infrared Communication

The infrared communication function of this watch uses an infrared (Ir) beam for communication in the same manner as the remote controllers of television sets and VCRs. Communication is performed between watches or between the watch and a personal computer by transmission and reception of this infrared beam by their respective infrared transmission/reception units.
*	The infrared communication function of this watch complies with the wrist watch infrared communication standard IrWW (IrDA for Wrist Watches).

A. Communication Range

The maximum distance infrared communication can be performed with this watch is 15 cm (5.9 inch) in the vertical direction to the infrared transmission/reception unit. Although directivity has a margin of about +15 deg. to -15 deg., the communication distance becomes shorter as the angle becomes wider.

* Remove any obstacles between the watches or between the watch and the personal computer during infrared communication. * Data may not be able to be transferred or an error may occur if other infrared communication devices are nearby during infrared communication. * Avoid moving the watch as much as possible during infrared communication. * Perform infrared communication within a temperature range of +10 deg. C to +35 deg. C (50 deg. F to 95 deg. F). Data may not be able to be transferred if outside this range. * Data may not be able to be transferred or an error may occur if infrared communication is performed directly beneath a fluorescent lamp or in direct sunlight. * When transferring data between the watch and a personal computer using infrared communication, the personal computer also must be set to be able to use infrared communication. Refer to the instruction manual of the personal computer for information on setting the personal computer for infrared communication.

B. Infrared Communication Mode Operating Procedure
The procedure for data transfer is performed with the "Infrared Communication Mode" of the watch.
	(1) The watch enters the infrared communication mode initial display when the lower left button (D) is pressed for at least 2 seconds and then released in any mode. (2) The menu changes each time the upper left button (C) is pressed once, and the menu of the selected menu is displayed when either the upper right button (B) or the EL light button is pressed once. (The menu indicated with an the * mark is the selected menu.) (3) The selected communication menu is activated when the upper right button (B) or the EL light button is pressed once when the lowermost menu is displayed.
