Okay I am a receptionsit and my boss wants me to reprogram our million year old Toshiba EKT6520-H phone, to update the auto dial. The problem is that I have no manual to do so just a quick reference guide. It isn't very helpful and gives little info. It tells me buttons to push in order to program but as far as I can see, these buttons do not exist! Help, I don't know what else to do.
