3/4 way down the left side of the logic board which is inside the front cover.>

The frequency must be inserted in six digits.  The decimal point must return
to be a valid frequency entry.  Also you must hold the function button while entering the frequency and
then press enter before releasing the function buttion.

>Function + 159357  (Enter program mode)

if the jumper has been removed a colon will now show up between the Ch and channel number
ex Ch 01  with jumper removed Ch:01.  You have only 30 seconds time between 
entries or the radio will time out and return to operation mode.
