(b) When the cable is disconnected from the negative (-) auxiliary battery terminal and the security lock setting has been enabled, multi-display operations will be disabled upon next startup unless the password is entered. Be sure to check the security lock setting before disconnecting the cable from the negative (-) auxiliary battery terminal.

SITUATIONS WHEN "BLUETOOTH" HANDS-FREE FUNCTION CANNOT BE USED

(a) In the following situations, the hands-free function cannot be used:

  • When outside of a reception area
  • When communication is being limited, such as when the line is overloaded
  • When there is an urgent communication from HELPNET or manual maintenance is being performed.
  • When phonebook data is being transferred from a cellular phone
  • When there is a dial lock on the cellular phone
  • When the cellular phone is malfunctioning
  • When the cellular phone is not connected
  • When the cellular phone battery charge is low
  • When the cellular phone is off
  • When the cellular phone is being used (connected to the Internet, an application is open, etc.)
  • In other situations when the cellular phone cannot be used.

(b) When there is a contract for three-way calling, it may be necessary to turn off the function.

(c) When there is a contract for HELPNET, the hands-free function cannot be used when HELPNET is being used. Furthermore, when a HELPNET operation is being performed, the call cannot be terminated by the usual termination method. When automatically waiting for an incoming connection, hands-free can be used.

PRECAUTIONS WHEN USING "BLUETOOTH"

(a) If the device has not been confirmed as a compatible device, it may not operate correctly.

(b) If the operating system and software of the "Bluetooth" device are not the latest versions, it may not operate correctly.

(c) If another radio wave transmitting device (Wi-Fi communication device, etc.) is transmitting within proximity to the "Bluetooth" device, it may not operate correctly due to mutual interference.

(d) As "Bluetooth" and "Wi-Fi" use the same 2.4 GHz frequency band, if the "Wi-Fi" setting or "Bluetooth" device is on, "Bluetooth" hands-free function may not operate correctly.

HINT:

When a "Bluetooth" connection is already established, interference with another radio wave transmitting device can be reduced. If there are any registered "Bluetooth" devices, establish the "Bluetooth" connection and then operate another radio wave transmitting device such as a Wi-Fi communication device.
