TCU E60, E87, E90: Registering the snap-in adapter (only in Korea)

From March 2005 onwards, the telephone system in Korea is set up as follows: The connection between the TCU control unit and the Bluetooth-capable snap-in adapter is a radio connection with Bluetooth radio standard. The connection between the snap-in adapter and the mobile phone is a wire connection.

So that the Bluetooth connection between the control unit and the snap-in adapter works, the snap-in adapter has to be registered once at the TCU control unit.

Procedure with CCC/M-ASK

The snap-in adapter is registered without the DIS tester. For the entire duration of the registration, a switched-off mobile phone must be inserted in the snap-in adapter.

1. On the Control Display, select the following menu:
   Start menu --> menu ”Settings” (press the controller) --> menu item ”Communication settings” --> menu item ”Bluetooth” --> menu item ”Settings”
   Activate Bluetooth. When Bluetooth communication has been activated, ”Bluetooth communication active” is displayed with a check mark at the start of the line.
   
2. Exit from the ”Settings” menu. In the ”Bluetooth” menu, select the menu item ”Telephone”. ”Bluetooth can be connected in this menu” is displayed.
   
3. Enter the Bluetooth passkey of the snap-in adapter via the Controller. This 4-digit number is located:
   
   • on the label attached to the snap-in adapter,
     
   • and on the accompanying sheet delivered with the snap-in adapter.
     
4. The connection setup between the TCU control unit and the snap-in adapter is then automatic. The connection setup can take up to 2 minutes. When the connection has been set up, the name of the snap-in adapter is displayed on the Control Display.
   

Procedure with RAD2

The snap-in adapter is registered without the DIS tester. For the entire duration of the registration, a switched-off mobile phone must be inserted in the snap-in adapter.

1. On the radio, press the ”MENU” button.
   
2. On the Control Display, select the ”TEL” item.
   
3. On the Control Display, select the ”BT ” item. The list of Bluetooth devices connected to the TCU control unit is displayed. The TCU control unit can support a maximum of 4 Bluetooth control units at one time. In order to be able to register a snap-in adapter, the list of connected Bluetooth devices may have a maximum of 3 entries. If the list has too many entries, entries must be deleted using ”DELETE” until the list has 3 or fewer entries.
   
4. Insert a switched-off mobile phone in the snap-in adapter. The LED of the snap-in adapter should light up or flash.
   
5. On the Control Display, select the ”SEARCH” item. ”Bluetooth devices pairable...” appears on the Control Display.
   
6. Wait until the following message appears on the Control Display: ”Ext. Device Ready!”. The waiting period can last up to 2 minutes.
   
7. On the Control Display, select the ”ADD” item.
   
8. Enter the Bluetooth passkey of the snap-in adapter on the Control Display. This number is located:
   
   • on the label attached to the snap-in adapter,
     
   • and on the accompanying sheet delivered with the snap-in adapter.
     
9. On the Control Display, confirm the entry with ”OK”.
   
10. If the registration of the snap-in adapter was successful, the LED of the snap-in adapter is no longer lit. In addition, the name of the snap-in adapter appears in the list of connected Bluetooth devices.
    All snap-in adapters have the same name. The currently active snap-in adapter is marked in the list with a check mark in front of its name. To check whether the present snap-in adapter is currently active, the mobile phone should be disconnected. If the present snap-in adapter was active, the check mark in front of the name of the snap-in adapter is replaced by a number on the Control Display.
    
11. If registration of the snap-in adapter was unsuccessful, the message ”Bluetooth pairing failed” appears on the Control Display.
    Possible causes of this are:
    
    • The Bluetooth passkey was incorrectly entered and does not match the Bluetooth passkey of the snap-in adapter. In this case, repeat the registration
      
    • The TCU control unit attempts to connect to another Bluetooth device. This can occur is there is a vehicle nearby with another snap-in adapter. In this case, remove all Bluetooth devices in the immediate surroundings and then repeat the registration.
      

Appendix: procedure for checking the operability of the LED of the snap-in adapter

1. Switch on terminal 15.
   
2. Insert a mobile phone in the snap-in adapter.
   If the LED of the snap-in adapter lights up, it is working properly. If the LED of the snap-in adapter does not light up, it is damaged.
