About the BLUETOOTH wireless technology
The BLUETOOTH wireless technology operates within a range of about 30 m (about 98 ft).
Supported version and profiles of the BLUETOOTH standard
A profile is a set of functions standardized for every characteristic of BLUETOOTH devices. The transmitter supports the following version and profiles of the BLUETOOTH standard.
Supported BLUETOOTH version: BLUETOOTH standard, version 5.0
Supported BLUETOOTH profile:
- A2DP (Advanced Audio Distribution Profile): Enables transmission and reception of high-quality music contents.
Maximum communication range
Use the BLUETOOTH wireless technology between the transmitter and a device that are located within about 30 m (about 98 ft) from each other.
Maximum communication range may shorten under the following conditions.
- There is an obstacle such as a person, metal, or wall between the transmitter and BLUETOOTH device.
- A wireless LAN device is in use near the transmitter.
- A microwave oven is in use near the transmitter.
- A device that generates electromagnetic radiation is in use near the transmitter.
Interference from other devices
Because BLUETOOTH devices and wireless LAN (IEEE802.11b/g) use the same frequency (2.4 GHz), microwave interference may occur and result in communication speed deterioration, noise, or invalid connection if the transmitter is used near a wireless LAN device.
Interference to other devices
Microwaves emitted from a BLUETOOTH device may affect the operation of electronic medical devices. Turn off the transmitter and other BLUETOOTH devices in the following locations, as it may cause an accident.
- Where inflammable gas is present, in a hospital, train, airplane, or a gas station
- Near automatic doors or a fire alarm
Note
- To be able to use the BLUETOOTH function, the BLUETOOTH device to be connected requires the same profile as the transmitter's. Note also that even if the same profile exists, devices may vary in function depending on their specifications.
- Due to the characteristics of BLUETOOTH wireless technology, there is a slight delay in playback on the BLUETOOTH device receiving audio or music in comparison to the one sending it.
- The transmitter supports security capabilities that comply with the BLUETOOTH standard to provide a secure connection when the BLUETOOTH wireless technology is used, but security may not be enough depending on the setting. Be careful when communicating using BLUETOOTH wireless technology.
- We do not take any responsibility for the leakage of information during BLUETOOTH communication.
- BLUETOOTH devices to connect with the transmitter must comply with the BLUETOOTH standards prescribed by Bluetooth SIG, Inc., and must be certified as compliant. While they comply with the BLUETOOTH standards, however, there may be cases that connection attempts fail; or operations on the device, contents displayed on the device, or behaviors of the device vary depending on the characteristics or specifications of the BLUETOOTH device.
- Noise or sound interruption may occur depending on the BLUETOOTH device connected with the transmitter, the communication environment or the usage environment.
- Establishing a BLUETOOTH connection between the transmitter and a device with a built-in radio or tuner may cause noise in audio from the device. The transmitter should not be used with such a device via BLUETOOTH connection.
- Keep the transmitter away from a device, such as a radio or a tuner. Use of the transmitter in the vicinity of such a device may cause noise in audio from the device.
