M22 Setup:

  1. Unplug the curly cord from the base of the telephone and plug it into the back of the amp into the handset port (where there is a picture of the telephone handset)
  2. Insert the coiled (pigtail cord) cable from the M22 port in the back of the amp labeled with the full telephone symbol into the handset cord port on the telephone (where you disconnected the curly cord from)
  3. To connect your headset, put the 2 halves of the Quick Disconnect™ (QD) connector together. Your headset and M22 are both supplied with QD connectors. Plug the headset into the front of the amp where there is a picture of a headset
  4. Put the batteries in the amp
    Note: There is a power cord available, however it is not shipped out with the amp
