Custom Programming

The Data I/O port allows
special channel programming
with the FP-75 programmer to
create new dedicated frequency
groups.  These frequencies can
then operate in sequence for
“roundabout” type channel
selection with the AST push
button.  A dedicated single
channel can also be programmed.

AutoSmart-Tuning

TM

  

Process

Plugging the earphone into the PR-75a receiver will automatically turn on
the receiver and initiate the AutoSmart-Tuning

TM

  process.  (The LED will

blink very rapidly during this process.)  The receiver will then tune itself to
the closest on-air transmitter in its vicinity.  Based on the first channel found,
the receiver will then determine the channel group to which it belongs for
multiple channel operation.
