Automatic recognition of the speed sensor ID
The speed sensor has its own ID, and the wristwatch measures in synchronization
with the ID. Two speed sensor IDs can be registered to one wristwatch, which can
automatically identify the 2 speed sensors once their IDs are registered in advance.
As a tire circumference is set to the speed sensor ID, wheel selection by manual op-
eration is no longer required, which was necessary with conventional units.
The speed sensor currently recognized is indicated with a sensor icon ( * or )
on the screen.
Procedure of automatic recognition
When the wristwatch changes to the Clock mode by its power-saving function, and
then returns to the Sports mode, automatic recognition of the speed sensor ID is
performed through the following procedure.
The wristwatch searches a sensor signal from the speed sensor ID-1. 1.
When the wristwatch receives a sensor signal from ID-1, it displays sensor icon 2.
on the screen, and starts measurement.
When the wristwatch cannot receive any sensor signal from ID-1, it searches a
sensor signal from ID-2.
When the wristwatch receives a sensor signal from ID-2, it displays sensor icon
3.
on the screen, and starts measurement.
When the wristwatch cannot receive any sensor signal from ID-2, it searches a
sensor signal from ID-1 again.
The wristwatch repeats synchronization through the procedure described above
even if it fails in synchronization for some reason, such as communication failure;
in such cases however, it takes time for recognition.
When the wristwatch cannot receive any signal from the speed sensor in 5 *
minutes, the power-saving mode is activated, and the wristwatch changes to the
Clock mode.
Switching the ID by manual operation
The speed sensor ID can be forcibly switched by manual operation from “Setting the
tire circumference” in the Setup mode. Use this operation in the following cases.
When the wristwatch cannot recognize the intended sensor signal, since the 2 •
registered speed sensors are nearby and both are sending a sensor signal.
When you want to switch the speed sensor ID immediately.
•
Once you switch the speed sensor ID by manual operation, the wristwatch *
continues to search only the speed sensor ID you switched when returning to
the Sports mode. When the wristwatch cannot receive any sensor signal in 5
minutes, the power-saving mode is activated, and the wristwatch changes to the
Clock mode. The wristwatch searches through the procedure of automatic rec-
ognition when it returns to the Sports mode.
