 General
Q. What is the difference between USB communication and infrared communication?
A. USB communication refers to communication using a USB cable connected between the USB terminal of a personal computer and the communication unit. Infrared communication refers to wireless communication using an infrared terminal of a personal computer and the infrared terminal of the watch. Cyber Aqualand Nx is compatible with both types of communication.


Q. Can I use a USB hub?
A. Yes, you can. But because it is up to HUB that you use, some types of USB hub may not be used.


Q. Something wrong with USB communication system. What happened?
A. Please check the following matters.
=> Isn't watch in Low power mode?
> Take out the watch from the communication unit then press A and D button simultaneously for more than 2 seconds. After the watch is switched to standard mode, attach the watch to the communication unit.
Please try transferring data after the watch face turns to the USB communication display.
=> Is the USB cable connected to PC and the communication unit?
> Connect the USB cable correctly.
=> Is a USB driver installed?
> If not, install PgmUSB Device.
=> Does PgmUSB Device have the "x" mark under Control panel - System - Device manager?
> If the "x" mark is checked, delete PgmUSB Device, then install it again.
=> Does your PC have OHCI (Open Host Controller Interface) type?
> With OHCI type USB controller, some communication errors occur because of the combination problem. In this case, use a USB controller of UHCI (Universal Host Controller Interface) type or infrared communication. (You can check the type of the controller with the System Property.)

If you cannot solve your problem even after reading above answers, please consult CITIZEN SERVICE CENTER.


Q. How long is the possible communication distance of the infrared communication function?
A. The maximum distance is 15cm with directivity margin of about +/-15 degree.


Q. What is the transmission rate of infrared communication and USB communication?
A. The maximum trasmission rate of both infrared communication and USB communication is 57.6kbps.


Q. Is the communication unit compatible with USB 2.0?
A. Yes, the communication unit can operate with the USB 2.0 interface, but the transfer rate is the same as that of USB 1.1.

=> The watch is not in the Infrared communication mode.
> Press and hold the D button for at least 2 seconds in any mode, and the watch is set in the infrared communication mode. Then, push the C button to select "toPC".
=>The infrared port is disabled in Device Manager in the Controla Panel of your computer.
> Enable the infrared port.
=>The communication speed is set faster than 57.6kbps.
> Set the communication speed less than 57.6kbps with infrared device driver. Please refer to the instruction manual of your perosnal computer or infrared adapter for information.
