Narrative:

Oakland airport has recently received new r-acd tower radar displays, ARTS 3-E, new landline communication system, all of which went on line at once. My training for the system was much less than FAA standard. This added stress, caused excessive 'head down' time resulting in a separation not ensured situation.
