Bluetooth

See the RF Troubleshooting chapter for Bluetooth troubleshooting information. When
the flash D450 or UEME have been replaced the ESN has to be reprogrammed. This
automatically includes reprogramming the BT address.

SIM

The hardware of the SIM interface from the UEME (D2200) to the SIM connector (X2700)
can be tested without a SIM card. When the power is switched on, the mobile terminal
checks for a 1.8V SIM card and then a 3V SIM card. The mobile terminal attempts this
four times, whereafter it displays "Insert SIM card".
