There is a second set of factory / service menu functions F01 to F59. WARNING: 
changing these may reset all the memories. If you intend to make any changes, record all 
the original values first. Most of these settings are unique to each radio and are 
determined by using alignment procedures described in the FT100 Service Manual.  
Do not change these values unless you are sure of what you are doing. To activate them 
put the transceiver in VFO mode and turn it off. Press and hold the A,B,C keys; while 
holding them in, press and hold in the [PWR] switch for 1/2 second to turn the transceiver 
on. Now let go of all keys. Then press and hold the FUNC key for 1/2 second to get to the 
menu and then rotate the select knob to get to a second menu (F01 to F59) after #66 or 
before #01. When you turn the rig off and back on it returns to the normal menu.
