5.2.1 Notes for Bluetooth

• The 2.4 GHz band used in the BHT travels in a straight line and has a trouble passing through human
bodies and other objects. Pointing the BHT directly at the other Bluetooth
avoid communication failure.
• Using the BHT near microwave ovens, industrial heaters, high-frequency medical equipment, and other
sources using the 2.4 GHz band may interfere with Bluetooth
• Electromagnetic noise from personal computers, refrigerators, and other home appliances may also
interfere with Bluetooth
• Environmental factors that can also interfere with Bluetooth
・Near large metallic objects or metallic dust
・Places surrounded by metallic walls
・Places subject to strong vibration
− Point −
Make sure that the environment is free of said interference factors and capable of Bluetooth

communication before developing the application.
Use the program that resends data when communication failure occurs.

Make sure that the BHT communicates properly with all equipment in the environment where

other equipment using the 2.4 GHz band is already operated or newly added to the existing
system.
If the environment changes (e.g., newly installed household appliances and movement/addition of

shelves or objects), make sure that the BHT communicates properly with all equipment again
before actual use.
