Connection Pins
These pins are for connecting with the charging or data transfer pins of the watch.
There are four connections pins. The two center pins are connected to the charging
or data transfer pins of the watch, while the two outside pins are connected to the
watch case.
Locking Tab
This tab is for holding and locking the watch to the connection pins.
Battery Cover
The battery cover is opened to install the batteries. Two batteries are installed in the
communication unit body and two batteries are installed inside the battery cover.
Leg (Removable)
The leg can be removed when attaching watch models having a metal band to the
communication unit.
2. 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 international 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°, 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°C to +35°C (50°F to 95°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.
