You cannot establish a Bluetooth connection.
-
Your IC recorder is turned off. Turn on the IC recorder and the smartphone, and then make sure that the Bluetooth function is turned on.
-
The battery of your IC recorder is running low or almost out of power. Charge the battery with a running computer.
-
The Bluetooth pairing information on your IC recorder or the smartphone is deleted due to initialization (settings, built-in memory, etc.). Establish a Bluetooth pairing all over again.
-
Your IC recorder and the smartphone are too apart from each other. Bring them closer. When the IC recorder and the smartphone are separated by a long distance, an attempt to establish a Bluetooth connection may fail or the established Bluetooth connection may be disconnected.
