Connection with any kind of accessory not possible

Accessory set

If the communicator does not connect to any kind of accessory it can be possible that the flash D353 has been changed or the
EEPROM has been erased without making an Accessory Set. Open under WinTesla menu Software/ Set Factory values/ and set
Accessory than try to connect the phone again.
Note! Sometimes it is possible that the connection takes a while.

MMC not formatable

If the communicator hangs up while formating the MMC, it is necessary to flash the phone with newes sw 4.13.
Note! When updating the phone sw, it is also necessary to update the MMC with the newes image. (See SB-023)
For a faster MMC-image update it is a good solution to use ext. drive for MMC. (See SB-018)
