Idect Carrera Combo Phone No Power?

"Idect carrera combo phone"- there is the main handset and a cordless handset; the manual says to plug in 3 cables into the "corded" base station (phone, handset & mains) and to put batteries into the "cordless" handset; but in reality it is the opposite; the cordless handset has no slot to put batteries into and comes with the mains power cable already hardwired into it; it is plugged in and charging; but the Main Corded station is without power, and there is nowhere to put batteries in it or a 2nd mains cable in the box to plug into it? so The 2 units are reversed to what the manual says they should be?
