4.1.1 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
Notes
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.
