I have recently been asked to take over a fairly new electra elite 48. im looking for which manual would cover it.it has (1)b48-u10ksu with a co18-u10 inslot s3,an identifiable card in s6 that has a flash card mounted on it, and last a r-u1 etu inslot s7. Any direction he list can give me to get up on board quickly would be appreciated. My customer needs sveral more extensions added and some others reprogrammed. thanks in advance
