Wireless Communication Technology
Bluetooth wireless communication technology allows communication between various Bluetooth devices without
using cables. Devices that can use this technology include computers, computer peripheral devices and
smartphones.
The receiver and the microphone of this unit are factory-set to communicate with each other. Therefore, operations
usually needed for Bluetooth devices such as pairing and passkey entry are not necessary. With any Bluetooth
device other than the receiver and the microphone of this unit, on the other hand, communication is not possible.
Note
The communication sensitivity of this unit may be affected by the following conditions:
When there are obstacles such as people, metallic objects, walls, or reflective surfaces between the front of the receiver and
the microphone.
When used in a wireless LAN system environment, near multiple Bluetooth devices that are operating, near a working
microwave oven, or where there are electromagnetic waves.
If the microphone is placed in close proximity to the camera, noises may also be included in the audio of video recordings due to
RF interference. Keep the microphone at least 1 m (3 ft.) from the camera during use.
Check the LINK lamps on the receiver and the microphone for the communication state.
Due to some surrounding factors, including poor radio conditions and a high number of obstacles between the receiver and the
microphone, the communication state between the two devices may deteriorate, causing audio interruptions or noises. If this is
the case, the LINK lamps blink in blue. Make sure that the two devices are located appropriately apart from each other, there are
no obstacles between them, and the LINK lamps are steadily lit in blue before you use the receiver and the microphone.
