Please, check following points if you are having problems with data transfer via computer's serial port:

• The current state of your heart rate monitor may be wrong. Check the User's Manual on how to set the heart rate monitor to the data transmission state.
• The selected heart rate monitor type may be wrong. Check the selection from the software settings.

• The selected interface unit type may be wrong. Check the selection from the software settings.
• The selected serial port may be wrong. The software's automatic serial port identification fails to identify free serial ports in some computers.

• A transmitter belt must NOT be worn since it may disturb data transmission.
• The distance between the heart rate monitor and the interface unit may not be too big (data transmission problems may occur if the bracelet passes under the heart rate monitor).
• The interface unit or its cable may be too close to an interference source (a computer, a video display unit, a cellular phone, etc.)
• Data transmission may be affected by another peripheral device (a mouse, a modem, etc.)
• The serial port may have been reserved by another program (a modem, a digital camera, etc.)
• The serial port may be directed to an internal infra red port (especially when using laptops)
• When using Macintosh computers, the interface unit must be provided with a separate battery.
• Data transmission problems may occur if the heart rate monitor battery is low.

• Check if data transmission works when the heart rate monitor is turned through 180 degrees on the interface unit. If it does, then one of the two receive coils in the interface unit may be faulty.
• Check if data transmission works with another computer.
• Check if serial port works with another device (a digital camera, a mouse, etc.).
• Check the serial port settings from the computer's BIOS settings.
• Check the operating system's serial port settings from the Windows' control panel.
