                             Icom U16 Programming
---------------------------------------------------------------------------
The U16 is made programmable by moving a jumper inside the unit, then try
holding [FUNC] down and entering 159357. You're now in programming mode.
Exit program mode with [FUNC] + [CLR].

Function + 159357  Enter programming mode (Function = [FUNC] key)

Offset Freq:     Hold [FUNC], Press [4], use [#] for up offset, [*] for
                 down offset, then enter freq to offset by (ie: [#] [0] [0]
                 [0] [0] [0] for no offset, [#] [0] [5] [0] [0] [0] for the
                 standard +5MHz UHF offset), [ENTER], Release [FUNC]
